Mitre box comparison 2026
The best mitre boxes, compared.
Top pick: EUIOOVM three-blade set Best value: Draper 48677 mini mitre block – About £5.12 for a 120 g block with 45° and 90° slots and 4.3 from 5,022 reviews, for small trim rather than skirting. Updated October 2026.
A mitre box is a slotted guide for a hand saw, used in the UK for skirting, architrave, dado, beading, frames, trunking, and coving. It is not a powered mitre saw, even when amazon.co.uk files a hand set under Mitre. Judge it by the internal channel, the moulded angles, whether you can fix it down, and whether the saw is a tenon saw or a short hacksaw. A higher price does not mean a higher star line. A 100 mm skirting board needs a larger throat. What to measure first is in the [mitre box buying guide](/hub/saw-accessories/mitre-box/sub/mitre-box-buying-guide). A 135° slot is not a sprung-coving bevel. The internal channel decides the job, not the printed length.

The EUIOOVM set is a high-impact polystyrene box, 10 x 6 x 30 cm and 429 g, with slots at 45°, 90°, and 135° and three pull-saw blades, at £19.78. Amazon files it under Mitre Saws and shows 5.0 from 2 reviews. Both UK reviews are positive, and one says a finger screw locks the pronged blade in the handle. Neither review describes a fault, so a complaint list is not available. A bag is included. The table says pneumatic, which conflicts with a hand pull-saw. Two reviews at £19.78 do not show how the polystyrene holds up, and capacity is not stated.
Pros
- Three pull-saw blades; one review says a finger screw locks the blade
- Both of the two UK reviews are positive
- 45°, 90°, and 135° on a 429 g polystyrene box
- A bag is included
Cons
- 5.0 from only 2 reviews
- Capacity is not stated
- The table says pneumatic, which conflicts with a hand pull-saw
- No review describes how the slots wear
Best for: You want a first pull-saw set for small frames and you accept two reviews as the whole record.
Less suitable: You are cutting skirting of unknown fit, or you want a score backed by hundreds of reviews.

Common questions
Is this a powered mitre saw?
No. Amazon files it under Mitre Saws. The bullets are a hand pull-saw set. The table says pneumatic, which conflicts with that.
How many reviews support the 5.0 score?
Two UK reviews. Both are positive. Neither describes a fault, so a complaint list is not available.
How do the blades change?
One review says a finger screw locks the pronged end in the handle. The box is high-impact polystyrene, 429 g, 10 x 6 x 30 cm.

The Draper 48677 is the best value in this set: a 120 g recycled-plastic mini block at £5.12, with 45° and 90° slots and two countersunk holes so you can screw it down. Across 5,022 amazon.co.uk reviews it sits at 4.3, and it is rank 2 in Mitre Boxes. It does not include a saw, so the cut depends on a blade you already own. The listing disagrees with itself on size, giving 200 x 35 x 50 mm in one place and 190 x 28 x 30 mm in another, and there is no 22.5° slot. Reviewers treat it as a small-trim block, which fits a 120 g body. At this price the limit is the size of the work, not the star line.
Pros
- 4.3 from 5,022 amazon.co.uk reviews, rank 2 in Mitre Boxes
- Two countersunk holes so you can screw the block down
- £5.12 for a 120 g block with 45° and 90° slots
- No saw in the box, so you use a blade you already own
Cons
- No 22.5° slot
- Listing size lines conflict: 200 x 35 x 50 mm and 190 x 28 x 30 mm
- Reviewers treat it as a small-trim block, not a skirting box
Best for: You already own a fine saw and you are cutting small beading or craft pieces at 45° or 90°.
Less suitable: You need a 22.5° slot, or the trim is skirting that will not sit in a mini block.

Common questions
Does it include a saw?
No. The listing is one mini mitre box. UK reviews use it with a saw the buyer already owns.
Which angles does it cut?
45° and 90° only. It does not state a 22.5° slot.
How big is it?
The listing disagrees with itself: 200 x 35 x 50 mm, 190 x 28 x 30 mm, and other centimetre lines. Weight is 120 g. Reviews treat it as a small-trim block.

The Rolson 58262 is a plastic mitre box with a 300 mm, 12 TPI tenon saw at £9.70, and it is rank 1 in Mitre Boxes. The slots are 22.5°, 45°, and 90°, the outside is given as 300 x 130 x 80 mm, and the set weighs 668 g. Amazon shows 4.3 from 907 reviews. One UK review puts the inside at about 6.5 cm and says 98 mm skirting did not fit. Some reviewers call the supplied saw blunt and buy another. The specification table also lists corded-electric, 4,500 rpm, and an AAAA battery, which conflicts with a hand tenon saw. The angles are the useful part; the channel and the blade are the limits.
Pros
- Rank 1 in Mitre Boxes, 4.3 from 907 reviews
- 22.5°, 45°, and 90° in one set at £9.70
- A 300 mm, 12 TPI tenon saw with a soft-grip handle is included
- Outside given as 300 x 130 x 80 mm, weight 668 g
Cons
- One UK review puts the inside at about 6.5 cm and says 98 mm skirting did not fit
- Some reviewers call the supplied saw blunt and buy another
- The spec table lists corded-electric, 4,500 rpm, and an AAAA battery, which conflicts with a hand saw
- No bench-fixing holes are stated
Best for: You are cutting architrave and small trim at 22.5°, 45°, or 90°, and you can use the supplied saw or swap it.
Less suitable: You need 98 mm skirting to pass through the channel, or you read the electrical table as a powered saw.

Common questions
Is it electric?
No. The title is a tenon saw and plastic box. The specification table also says corded-electric, 4,500 rpm, and an AAAA battery. Those lines conflict with the bullets.
Will it take 98 mm skirting?
The bullets give the outside as 300 x 130 x 80 mm. One UK review says the inside is about 6.5 cm and 98 mm skirting did not fit.
What saw is included?
A 300 mm tenon saw stated at 12 TPI, with a soft-grip handle. Some UK reviews call that saw blunt and buy another.

The Viganoc V014 is a 150 g junior set at £9.99: a 150 mm bi-metal hacksaw and a small block with 45° and 90° only. Amazon shows 4.3 from 157 reviews, and the rank is 3 in Hacksaws, not in Mitre Boxes. UK reviews use it for small mitre cuts, tile trim, and crafting. No skirting size is stated. One review says the bracket cannot be secured and slides. Another says the blade and the retaining piece were missing, even though the bullets include a bi-metal blade. The table says 32 teeth on a 15 cm blade, which makes this a craft saw rather than a skirting box.
Pros
- 4.3 from 157 reviews
- A 150 mm bi-metal blade is listed, with a 45° and 90° block
- UK reviews use it for tile trim and small mitres
- 150 g, so it packs into a small kit
Cons
- No skirting size is stated; reviews keep it to small cuts
- One review says the bracket cannot be secured and slides
- One review says the blade and the retaining piece were missing
- Ranked 3 in Hacksaws, not in Mitre Boxes
Best for: You are cutting tile trim, models, or other small pieces at 45° or 90°.
Less suitable: You need skirting capacity, a block you can screw down, or a 22.5° joint.

Can you fix the block down?
The listing does not state screw holes. One UK review says the bracket cannot be secured and slides.
Does a blade always arrive?
One UK review says the blade and the retaining piece were missing. The bullets do include a bi-metal blade.

The Stanley 1-20-600 is a clamping mitre box and saw at £19.29, with slots at 90°, 45°, and 22.5° and a stated blade length of 350 mm. A quick cam lock is listed, and UK reviews describe twist pegs plus a front lip so you can clamp the box to the bench. It weighs 1.05 kg, and Amazon shows 4.2 from 2,604 reviews, rank 4 in Mitre Boxes, with a 1 year manufacturer warranty. Several reviews keep the box and call the supplied saw coarse or blunt. They also say the saw eventually cuts into the plastic base. Width is not stated. The specification table lists AC power, 4,500 rpm, a round blade, and a lithium battery, which conflicts with this hand tool, so the clamp is why the review count is high and the saw is the part many buyers replace.
Pros
- Cam lock and pegs hold the work; reviews describe a front lip for clamping to the bench
- 4.2 from 2,604 reviews, rank 4 in Mitre Boxes
- Slots at 90°, 45°, and 22.5°, with a 350 mm blade length stated
- 1.05 kg, with a 1 year manufacturer warranty
Cons
- Several UK reviews call the supplied saw coarse or blunt
- Reviewers say the saw eventually cuts into the plastic base
- Width is not stated
- The spec table lists AC power, 4,500 rpm, a round blade, and a lithium battery, which conflicts with a hand box
Best for: You will clamp the box for repeat 22.5°, 45°, and 90° cuts, and you may fit your own saw.
Less suitable: You need a stated internal width, or you read the electrical table as a powered mitre saw.

No. The bullets are a clamping box and a saw. The table also lists AC power, 4,500 rpm, a round blade, and a lithium battery. Those fields conflict with the product.
How does it hold the timber?
The listing states a quick cam lock. UK reviews describe twist pegs and a front lip so the box can be clamped to the bench.
What do reviewers say about the saw?
Several UK reviews keep the box and call the supplied saw coarse or blunt. They also say the saw eventually cuts into the plastic base.

The Tolsen 31017 is the top pick in this set: a high-impact plastic box with a 100 mm internal channel, slots at 22.5°, 45°, and 90°, and a 300 mm, 13 TPI, 0.9 mm 65Mn back saw, at £15.90. The outside is 30 x 14 x 7 cm, and two countersunk holes plus a non-slip front lip let you screw it to the bench. Amazon shows 4.2 from 1,356 reviews, rank 5 in Mitre Boxes. Some reviews prefer the box to the saw. One order arrived without the box. One review found the set awkward until it was screwed down. Weight is not stated. The channel and the fixing are why it leads; the saw is the part reviewers are quicker to replace.
Pros
- 100 mm internal channel, the clearest capacity in this set
- 22.5°, 45°, and 90°, plus a 300 mm, 13 TPI, 0.9 mm saw
- Two countersunk holes and a non-slip front lip
- 4.2 from 1,356 reviews, rank 5 in Mitre Boxes
Cons
- Some reviews prefer the box to the supplied saw
- One order arrived without the box
- One review found it awkward until it was screwed down
- Weight is not stated
Best for: You are cutting skirting or architrave up to the 100 mm channel and you will screw the box to a bench.
Less suitable: You want the saw to be the strong half of the set, or you want a pocket-size block.

The Hanpex X017-UK is a 300 mm ABS box at £13.99 with no saw. Slots are 45°, 90°, and 135°, and the bullets cap the work at 100 mm wide and 53 mm thick, with a maximum blade thickness of 2 mm. It weighs 320 g. Amazon shows 4.2 from 179 reviews, rank 17 in Mitre Boxes. UK reviews say the teeth wear the plastic and that it is not a long-life tool. One buyer screwed it to the bench and used their own tenon saw. The table’s 12 inch blade length matches the 12 inch box claim, not a supplied saw, so you need a fine saw of your own and you should expect the slots to open up.
Pros
- Stated capacity 100 mm wide and 53 mm thick
- Slots at 45°, 90°, and 135°
- 4.2 from 179 reviews
- 320 g ABS box; one reviewer screwed it down and used their own tenon saw
Cons
- No saw is included
- UK reviews say the teeth wear the plastic
- Reviewers do not treat it as a long-life tool
- No 22.5° slot
Best for: You already own a tenon saw and the trim is within the stated 100 mm width and 53 mm thickness.
Less suitable: You need a saw in the box, a 22.5° slot, or daily use of the same slots.

The GARTOL JDJ-UK2025 is a polystyrene box with slots at 45°, 90°, and 135°, sold with pull-saw blades stated at 10, 17, and 25 TPI, at £15.99 and 490 g. Amazon shows 4.2 from 58 reviews, rank 7 in Mitre Boxes. UK reviews praise the saw and say the polystyrene box flexes. One review says heavy clamping distorts it. Another says 3 inch dado did not fit, and that the set suits beading and small frames. Overall capacity is not stated, and the table says 9 teeth, which conflicts with the TPI bullets. The handle is thermoplastic rubber, so the blades are the reason to buy it and the box is the part that moves.
Pros
- Three pull-saw blades stated at 10, 17, and 25 TPI
- 4.2 from 58 reviews, and reviewers praise the saw
- Slots at 45°, 90°, and 135°
- 490 g, with a thermoplastic-rubber handle
Cons
- UK reviews say the polystyrene box flexes, and heavy clamping can distort it
- One review says 3 inch dado did not fit
- Overall capacity is not stated
- The table says 9 teeth, which conflicts with the TPI bullets
Best for: You are cutting beading or small frames and you want a choice of pull-saw blades.
Less suitable: You are cutting 3 inch dado, or you need to clamp the box hard.

The HAUTMEC HT0034 pairs a 150 mm, 24 TPI bi-metal hacksaw with an aluminium mitre box of 13.5 x 3.2 x 4.8 cm, at £10.99 and 166 g. Amazon shows 3.9 from 1,714 reviews. Reviews use it for trunking, edging, and small beading, and say it is too small for a lot of beading. More than one UK review says the first cut enters the aluminium slot and leaves it offset. The blade is reported to blunt quickly, so a spare is worth having. A short bench tab appears in one review, and a case is included. The angles are 45° and 90° only.
Pros
- 3.9 from 1,714 reviews, a large sample for a mini set
- A 150 mm, 24 TPI bi-metal blade and a case are listed
- Aluminium box, 13.5 x 3.2 x 4.8 cm, used for trunking and small edging
- One review mentions a short bench tab
Cons
- More than one UK review says the saw cuts into the aluminium slot and leaves it offset
- Reviews say the blade blunts quickly
- Too small for a lot of beading, and there is no 22.5° slot
- Rank 22 in Hacksaws
Best for: You are cutting plastic trunking or narrow edging, and you keep a spare 150 mm blade.
Less suitable: Your beading is wider than the 3.2 cm box, or you need the slot to stay unworn.

The Novastream XJCLQ is an adjustable block stated from 85° to 180°, in ABS and stainless steel, at £8.99 and 310 g. The bullets say it takes baseboards up to 1.2 inches and that a gear lock holds the angle. There is no saw. Amazon shows 3.7 from 7 reviews and rank 29 in Mitre Boxes. The listing has no review text, so neither praise nor a fault can be quoted. The included-components line says carpet fitting tools, which conflicts with the title. Seven reviews and a 1.2 inch claim are not enough to treat this as a skirting box.
Pros
- Stated range 85° to 180° with a gear lock
- Bullets say baseboards up to 1.2 inches
- ABS and stainless steel, listed at 310 g
Cons
- 3.7 from only 7 reviews, and the listing has no review text
- No saw is included
- The included-components line says carpet fitting tools, which conflicts with the title
Best for: You want an adjustable block for narrow baseboard and you accept that seven reviews, with no written comments, are the whole record.
Less suitable: You need a 22.5° slot, or you want other buyers to have described the cut.

The Magicbox set is three SK5 pull-saw blades in a push-button handle, with a box slotted at 45°, 90°, and 135°, at £21.99 and 430 g. Amazon shows 3.5 from 17 reviews, and the rank is 2 in Mitre Saws rather than Mitre Boxes. The bullets also say four guide positions. Reviews split: one buyer made four picture frames, and another says the slots are too wide, the saws wobble, and they cut the plastic. Overall capacity is not stated. A case is included, and the dimensions are 30 x 9.2 x 5 cm. At this price the slot width is the complaint that matters.
Pros
- Three SK5 blades and a push-button change
- 45°, 90°, and 135°, with four guide positions stated
- One review completed four picture frames
- A case is included, and the set weighs 430 g
Cons
- 3.5 from 17 reviews
- One review says the slots are too wide, the saws wobble, and they cut the plastic
- Capacity is not stated
- £21.99 is the highest price here, on a thin review count
Best for: You are making small picture frames and you check that the blade sits in the slot before you cut more timber.
Less suitable: You need a close-fitting slot, a stated capacity, or a lower price for the same three-blade idea.

The BPTZYLN FWHQW is an adjustable block listed from 90° to 180° at £7.89, with a guide pin and no saw. The amazon.co.uk line is 2.3 from 4 reviews, and the rank is 26 in Mitre Boxes. One UK review says the angle still moves when the lock is set. Two others keep it to bath trim, beading, and small craft. One review says 4.5 inch skirting does not fit, and puts the practical width at moulding under about 3 cm. The listing’s 1 x 1 x 1 cm line conflicts with the 260 g weight, so four reviews and a slipping lock are a thin basis for a skirting joint.
Pros
- Stated range 90° to 180°, which a fixed 45° box does not offer
- A guide pin is listed
- £7.89 and a stated weight of 260 g
Cons
- 2.3 from only 4 amazon.co.uk reviews
- One UK review says the angle still moves when locked
- One review says 4.5 inch skirting does not fit, and limits it to moulding under about 3 cm
- The dimension line says 1 x 1 x 1 cm, which conflicts with 260 g
Best for: You are cutting bath trim or small craft and you will check that the lock holds before you commit a piece.
Less suitable: You are mitring skirting, or you need an angle that stays put once you lock it.

Common questions
Is this a slotted mitre box?
No. It is an adjustable block stated from 90° to 180°, with a guide pin. It does not list 22.5° or 45° slots.
Does the angle stay locked?
One UK review says the angle still moves when locked. Two other reviews limit it to bath trim, beading, and small craft.
Will it take 4.5 inch skirting?
One UK review says no, and that it suits moulding under about 3 cm wide. The listing’s 1 x 1 x 1 cm line conflicts with the 260 g weight.
How we compared
Twelve amazon.co.uk mitre boxes and mitre-box sets were scored out of 100 from the listing facts in this set. Prices, stars, and review counts are the UK lines stored on 16 October 2026. This is not a lab test, and the scores do not rank the wider UK market. Points come off for fewer than 10 reviews, a size or parts line that conflicts with the product, electrical or pneumatic fields on a hand tool, and one report that the box or the blade was missing. The five weights below sum to 100.

Mitre box buying guide
These bands are a rule of thumb from the twelve shelf prices only, captured on 16 October 2026. Entry, about £5 to £11, covers the Draper mini, both adjustable blocks, the Rolson, the Viganoc, and the HAUTMEC. Mid, about £14 to £16, covers the Hanpex box, the Tolsen set, and the GARTOL set. The upper end of this set, about £19 to £22, covers the Stanley clamping set, the EUIOOVM, and the Magicbox. The Magicbox is the dearest and has 17 reviews at 3.5. Stars are listing figures.
What is a mitre box?
A mitre box is a slotted guide for a hand saw. You drop the timber into the channel and run the saw through a fixed slot so the cut follows 90°, 45°, or, on some boxes, 22.5° or 135°. In the UK it is the hand tool for skirting, architrave, dado, beading, frames, trunking, and coving. It is not a powered mitre saw, even when amazon.co.uk files a hand set under Mitre Saws. A 135° slot is not a sprung-coving bevel. The internal channel decides the job, not the printed length.
Best for
- First-time fitting of architrave or dado that fits the channel
- Occasional beading, trunking, or a picture frame
Not ideal for
- Skirting taller than a measured 100 mm channel
- Large sprung coving, or walls that are not square
Mistakes to avoid
- 1
Buying on the star line
A high star line on a mini block is still a mini block. The Draper is 4.3 from 5,022 reviews and reviewers use it for small trim. The EUIOOVM is 5.0 from two reviews. Stars do not state the channel.
- 2
Reading length as capacity
The Rolson outside is 300 x 130 x 80 mm. One UK review puts the inside near 6.5 cm and says 98 mm skirting did not fit. Stanley states a 350 mm length and does not state a width.
- 3
Trusting an rpm line on a hand tool
Stanley’s table lists AC power, 4,500 rpm, and a lithium battery. Rolson’s lists corded-electric. The bullets are hand tools. A rank under Mitre Saws does not make the set a powered compound saw.
What to weigh up
Internal capacity
HighInternal capacity is the inside of the channel, not the printed length of the box. The clearest figure in this set is the Tolsen 31017, which states a 100 mm internal channel. Hanpex states a maximum of 100 mm wide and 53 mm thick, and it does not include a saw. Novastream states baseboards up to 1.2 inches, with 3.7 from 7 reviews and no review text. One Rolson review puts the inside near 6.5 cm and says 98 mm skirting did not fit, even though the outside is given as 300 x 130 x 80 mm.
Angles, saw, and fixing
High90° and 45° cover a rectangular corner. 22.5° is on the Stanley 1-20-600, the Rolson 58262, and the Tolsen 31017. The Draper mini is 45° and 90° only. Hanpex, GARTOL, EUIOOVM, and Magicbox list 45°, 90°, and 135°. A 135° slot is not a sprung-coving bevel, and a flat 45° slot is a poor match for large sprung coving. Wickes and Toolstation say coving goes in wall-edge up. A backsaw suits a full-size plastic box. Tolsen includes a 300 mm, 13 TPI saw.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Beading and picture frames
You only need beading, trunking, or a picture frame. A mini block is the fit, not a 350 mm clamping set. The Draper is 45° and 90° only, and it does not include a saw.
Repeat cuts with a clamp
You want 22.5°, 45°, and 90° and a box you can clamp to the bench. Stanley reviews describe cam pegs and a front lip. Several of those reviews keep the box and replace the saw. Width is not stated.
Common questions about mitre boxes
Which mitre box is the top pick in 2026?
The top pick in this set is the Tolsen 31017, about £15.90 on amazon.co.uk on 16 October 2026. It states a 100 mm internal channel, slots at 22.5°, 45°, and 90°, a 300 mm saw, and two screw holes. Amazon shows 4.2 from 1,356 reviews. It leads on the channel and the fixing, not on a lab measurement of the angle. Skip it if you only want a pocket block for beading.
How much does a mitre box cost on amazon.co.uk?
As a rule of thumb from these twelve shelf prices on 16 October 2026, entry is about £5 to £11, including the Draper at £5.12 and the Rolson at £9.70. Mid is about £14 to £16, including the Tolsen at £15.90. The upper end of this set is about £19 to £22, from the Stanley at £19.29 to the Magicbox at £21.99. A higher price here does not mean a higher star line.
What should you check before you buy a mitre box?
Check the internal channel, not the printed length. Tolsen states 100 mm. Hanpex states 100 mm wide and 53 mm thick. One Rolson review puts the inside near 6.5 cm. Then check the angles. 90° and 45° cover a rectangular corner, and 22.5° is only on some full-size boxes. A backsaw suits a full-size box. A 150 mm hacksaw does not cross skirting. Fix the box down, and ignore rpm lines on a hand-tool table.
Will a mitre box cut 100 mm skirting?
Only if that box states an internal size the board can enter. The Tolsen 31017 states a 100 mm internal channel. Hanpex states 100 mm width and 53 mm thickness. The Draper is a mini block that reviewers use for small trim. One Rolson review says 98 mm skirting did not fit an inside of about 6.5 cm. If the board will not enter a measured box, this set does not cover it.
Is a 135° slot the same as a coving bevel?
No. A 135° slot is not a sprung-coving bevel, and a flat 45° slot is a poor match for large sprung coving. Wickes and Toolstation say coving goes in wall-edge up, and that internal and external corners use opposite 45° slots. Hanpex, GARTOL, EUIOOVM, and Magicbox list 135° among their slots. That angle does not turn the set into a powered compound saw.
Are the Stanley and Rolson mitre boxes electric?
No. Both are hand tools. The Stanley 1-20-600 bullets are a clamping box and a saw. Its table also lists AC power, 4,500 rpm, and a lithium battery, which conflicts with the product. The Rolson 58262 is a tenon saw and plastic box. Its table lists corded-electric and 4,500 rpm, which conflicts with the bullets. Ignore those lines. The useful Stanley feature in the reviews is the cam lock, not a motor.
When is a hand mitre box the wrong tool?
A hand box is the wrong tool when the skirting will not enter a measured channel, or when many corners are not square. Checkatrade says to scribe internal skirting in that case. A flat 45° cut will not close the gap. Call a joiner before you buy a powered saw you have not used. A guided circular saw is a different comparison, starting with a circular saw guide rail.
Our verdict
The top pick is the Tolsen 31017 when the trim fits a stated 100 mm channel and you will screw the box down. It is about £15.90, with 22.5°, 45°, and 90° slots and a 300 mm saw, and 4.2 from 1,356 reviews. Some reviews prefer the box to the saw, and one order arrived without the box. The best value is the Draper 48677 at about £5.12, 4.3 from 5,022 reviews, for small trim at 45° and 90° when you already own a fine saw. It is not a skirting box.
