The best 315mm x 30mm circular saw blades, compared.
Top pick: Trend CSB/31572 fine blade, 72 teeth Best value: BGS 3957 carbide blade, 30 teeth – About £19.03 with 4.5 from 279 reviews, 30 teeth and 4,200 rpm stated. The details field says Metal, and one UK firewood note is about four months. Updated 22.10.2026.
A 315mm x 30mm circular saw blade is a TCT disc for a site or workshop saw bench whose manual specifies that diameter and a 30 mm arbor. It is not a 305 mm mitre blade, and it is not a handheld blade around 184 mm. You tell a suitable disc apart by tooth count, kerf, plate thickness, hook angle and the maximum speed marked on the plate, then by whether the listing names wood. Those checks stay the same when the models change. Diameter and bore have to match the saw manual. The riving knife should be thicker than the plate and thinner than the kerf. A coarse tooth count suits ripping, and a finer count suits a crosscut. More teeth are not automatically better. The marked maximum speed must be at or above the saw’s spindle speed. How to apply those checks is in the [315mm x 30mm circular saw blade buying guide](/hub/saw-accessories/315mm-x-30mm-circular-saw-blade/sub/315mm-x-30mm-circular-saw-blade-buying-guide).

Question 1 of 2
What is the main cut?
The Trend CSB/31572 is a 72-tooth fine TCT blade at £76.95, and the only United Kingdom text in the file says the cut was nice and clean. The listing is 5.0 from five reviews, with two texts in the raw and only one of them from the UK. That line does not name the timber, the saw, or how long the edge lasted. The title states a 3.2 mm kerf, a +10° hook, and a fine finish, and the item type calls it a trimming crosscut blade. The item-thickness field is 2.2 mm, and the bullets name softwood, hardwood, plywood, MDF, and hardboard, plus the Makita 2712 and the Metabo TKHS 315 C and M. Maximum rpm is not in this amazon raw. Five stars from five ratings is a thin sample beside the 48-tooth blade’s 95 reviews. The manufacturer page gives this code a 15° hook, while the amazon title says +10°, so those two figures are not one settled number.
Pros
Cons
Best for: A fine crosscut when you accept a five-review sample and the +10° hook printed on the amazon title.
Less suitable: A coarse rip, and anyone who wants a large UK review sample before paying £76.95.
Specifications
Common questions
What finish does the CSB/31572 title claim?
The title says fine finish, 72 teeth, 3.2 mm kerf, and +10° hook. The item type is a trimming crosscut TCT blade. The item thickness field is 2.2 mm.
How many UK reviews are in the raw?
The listing is 5.0 from 5 reviews. The raw has two texts, one of them from the United Kingdom, and that text says the cut was nice and clean. It does not name the timber or the saw.
Which saws does the bullet list?
The bullet names the Makita 2712 and the Metabo TKHS 315 C and TKHS 315 M, and says many more. The compatible-devices field says circular saws. The question about fitting every table saw is unanswered.
The Draper 25782 is a 72-tooth TCT blade for wood at £28.59, and neither United Kingdom text in the file describes a cut. The listing is 4.7 from nine reviews, with two texts in the raw. One says it is a great blade of good quality. The other judges the quality from unpacking and has not used the blade yet. The bullets name hardwood, softwood, MDF, chipboard, and plywood, and compatibility with most 315 mm circular saws that have a 30 mm bore. Kerf, hook, plate, and maximum rpm are absent, so a riving-knife check cannot start from this page. No defect is reported, and no timber or saw is named. Nine ratings with two short texts is a thin basis for choosing a fine tooth count.
Pros
Cons
Best for: A 72-tooth wood blade when you will take the kerf from the saw manual or Draper’s own page, not from this amazon row.
Less suitable: A buyer who needs a described UK cut before choosing 72 teeth.
Specifications
Common questions
What tooth count does Draper 25782 state?
The title states 72 teeth on a 315 x 30 mm TCT blade for wood. Kerf, hook, plate, and maximum rpm are not in this raw.
Which materials are in the bullets?
Hardwood, softwood, MDF, chipboard, and plywood. The bullet also says it is compatible with most 315 mm circular saws with a 30 mm bore. No saw model is named.
Have the UK reviews described a cut?
No. One UK review judges the quality from unpacking. The other says it is a great blade of good quality. Neither names a saw or a timber. The listing is 4.7 from 9 reviews.
The Draper 25873 is a 96-tooth TCT blade for wood at £36.49, and the raw has no United Kingdom review text. The listing is 4.7 from six reviews. The two texts in the file are from Italy and Spain: one says the product seems well assembled, and the other says it was as described. Neither names a timber, a saw, or how long the edge lasted. The bullets name hardwood, softwood, MDF, chipboard, and plywood, and the compatible-devices line says most standard circular saws with a 30 mm bore designed for 315 mm blades with 96 teeth. Kerf and hook are not in the raw. An item-thickness field of 1.2 cm is printed and is not labelled as plate or kerf, so it should not be used as either. A 96-tooth count is the finest in this set, and this file does not show what that edge does on plywood.
Pros
Cons
Best for: A 96-tooth wood blade when the saw is already 315 mm by 30 mm and you will confirm the kerf elsewhere.
Less suitable: A coarse rip, and anyone treating six ratings with no UK text as proof of a furniture edge.
Specifications
Common questions
What does the Draper 25873 title state?
It is a TCT circular saw blade for wood, 315 x 30 mm, 96 teeth. The compatible-devices line says most standard circular saws with a 30 mm bore designed for 315 mm blades with 96 teeth.
Is 1.2 cm the plate thickness?
The raw prints an item thickness of 1.2 cm and does not label it as plate or kerf. Kerf, hook, and maximum rpm are not in this raw, so the table leaves plate blank.
Are there UK reviews in the file?
No. The listing is 4.7 from 6 reviews. The two texts in the raw are from Italy and Spain. One says the product seems well assembled. The other says it was as described.
The Trend CSB/31548 is a 48-tooth combination TCT blade, and UK reviewers on amazon.co.uk use it for a rip of 50 mm oak and for internal window ledges that had to fit tightly. At £37.00 the listing is 4.6 from 95 reviews, with 15 United Kingdom texts among the 20 in the file. One of those reviews describes seven 4 m lengths of 50 mm oak ripped into 25 mm, and still withholds a fifth star. Other UK notes put it on a Sheppach TKU in place of a ten-year-old 315 mm blade, and on a second-hand Sawking table saw that then cut like new. The title states a 3.2 mm kerf and a +15° hook, the item-thickness field is 2.2 mm, and the bullets name softwood, hardwood, plywood, MDF, and hardboard, while the details field says Stone. Maximum rpm is not in this amazon raw, and the question of whether it fits every table saw is unanswered. One UK review used it for a day, put the old blade back, and called the cut terrible.
Pros
Cons
Best for: Mixed ripping and crosscutting on a 315 mm bench with a 30 mm arbor, when you want a stated 3.2 mm kerf.
Less suitable: A saw whose manual limits body thickness to 2 mm or less, and a job that needs the maximum rpm printed on the listing.
Specifications
Common questions
What does the Trend CSB/31548 listing state for teeth, kerf, and hook?
The title states 48 teeth, a 3.2 mm kerf, and a +15° hook, and calls it a medium finish. The item thickness field is 2.2 mm. Maximum rpm is not in this raw.
Which saws does the listing name?
The compatible-devices line names the Makita 2712 and the Metabo TKHS 315 C and TKHS 315 M, and says many more. UK reviews also mention a Sheppach TKU and a Sawking table saw. The listing does not answer whether it fits every table saw.
What do the UK reviews say about the cut?
Several UK reviews describe a clean, straight cut, including a rip of 50 mm oak and internal window ledges. One UK review used it for one day and put the old blade back.
The Draper 24969 is a 48-tooth TCT blade for wood at £27.07, and the only review text in the file says it fits the requirement exactly. The listing is 4.6 from four reviews, so the star line sits on a very small sample. That UK text also says the buyer needed a new blade and that it looks great, and it does not name the saw, the timber, or how long the edge lasted. The bullets name hardwood, softwood, MDF, chipboard, and plywood, with precision-ground carbide teeth, and they say it suits most 315 mm saws with a 30 mm bore. Kerf, hook, plate, and maximum rpm are not in this amazon raw, so a riving-knife check cannot start from the listing alone. A consumable warranty is named, without a term in the product data. The printed item dimensions, 12 L x 320 W mm, are not a plate thickness.
Pros
Cons
Best for: A 48-tooth wood blade when you will confirm the kerf from another source before you set the knife.
Less suitable: Anyone who needs the kerf and the hook printed on the amazon listing before they buy.
Specifications
Common questions
What materials does the Draper 24969 listing name?
The bullets say hardwood, softwood, MDF, chipboard, and plywood, with precision-ground carbide teeth. The title says it is a TCT blade for wood, 315 x 30 mm, 48 teeth.
Is the kerf in the amazon raw?
No. Kerf, hook, plate, and maximum rpm are not in this raw. The item dimensions are printed as 12 L x 320 W mm.
What does the only review say?
The one UK review says the buyer needed a new blade and that it fits the requirement exactly. It does not name the saw, the timber, or how long the edge lasted. The listing is 4.6 from 4 reviews.
The BGS 3957 is a 30-tooth carbide blade at £19.03, and one UK reviewer uses it for firewood about two hours a week. The listing is 4.5 from 279 reviews, the largest count in this set, with eight United Kingdom texts in a 50-review sample. That firewood review reports about four months of life, against 12 to 18 months the same buyer reports for dearer blades. Other UK texts call it good value and say they would buy it again, including a buyer who keeps reordering. The bullets state a 2.2 mm plate, a 3.0 mm cutting width, 30 teeth, and 4,200 rpm, and they do not name wood. The details field says Compatible Material: Metal, and the question about cutting metal has no answer. No United Kingdom review in the sample reports a lost tooth, while French, Belgian, and German texts in the same file report missing or detached carbide tips.
Pros
Cons
Best for: Rough firewood and general ripping when you want the £19.03 price and can accept a short stated life.
Less suitable: A metal-cutting job, a furniture edge, and any saw whose manual rejects a 2.2 mm plate.
Specifications
Common questions
Does the BGS listing say it cuts metal?
The details field says Compatible Material: Metal, and a listing question asks whether it can cut metal, with no answer. The bullets state carbide teeth, 315 mm, 30 mm bore, 2.2 mm plate, 3.0 mm cutting width, 30 teeth, and 4,200 rpm. They do not name iron, steel, or wood.
What do UK reviews use it for?
UK texts call it good value. One UK review used it for firewood about two hours a week and reported about four months of life, against 12–18 months for dearer blades the same buyer uses.
Are lost teeth in the UK reviews?
No United Kingdom review in the 50-review sample reports a lost tooth. French, Belgian, and German reviews in the same file do report missing or detached carbide tips.
The Trend CSB/31524 is a 24-tooth coarse rip blade, and UK reviewers use it to resize long reclaimed 7 x 2 rafters and to break down old pallets. At £32.70 it is 4.5 from 70 reviews, with nine United Kingdom texts in a file of 13. One UK review reports straight cuts on those rafters for a shed, with the edge still noted after a few weeks. Another describes about two years of hard table-saw use, including logs and kindling, and calls it excellent value. The title states a 3.2 mm kerf and a +15° hook, the item-thickness field is 2.2 mm, and the bullets name softwood, hardwood, plywood, MDF, and hardboard. One UK reviewer hit missed nails in reclaimed timber mid-cut and reported no damage, which is one incident and not a nail-resistant rating. Several of the UK texts are a single line and do not describe the cut, and maximum rpm is not in this raw.
Pros
Cons
Best for: Rough ripping, pallets, and breaking down timber on a 315 mm saw with a 30 mm bore.
Less suitable: A furniture edge, and a Makita 2712 if you follow a manual that limits body thickness to 2 mm or less.
Specifications
Common questions
What cut does Trend label on CSB/31524?
The item type is a rip TCT blade and the title says coarse finish, 24 teeth, 3.2 mm kerf, and +15° hook. The bullets also name softwood, hardwood, plywood, MDF, and hardboard.
What plate thickness is in the raw?
The item thickness field is 2.2 mm. The title does not repeat a separate plate figure, and maximum rpm is not in this raw.
Do the UK reviews report damage from nails?
One UK review hit missed nails in reclaimed rafters mid-cut and reported no damage. Other UK texts praise straight cuts, pallet work, and about two years of hard use. No lost tip is named in this sample.
Shelf prices, stars and review counts are the amazon.co.uk figures behind the scores dated 21 October 2026. This is not a laboratory cut. A kerf, hook, plate, maximum rpm or material counts only when that listing prints it. A manufacturer page is not used to fill a gap in the table. Stars are not an error band. Each stored score is out of 100 and is shown here divided by 10. The highest score is the top pick. Best value is a different listing: the lowest shelf price in the set, with a large review count.
Listing fit
30%Named teeth, kerf, hook, plate, a wood list and a maximum rpm score up. A missing kerf, a missing rpm, or a details field that says Metal with no wood bullet scores down. A details field that says Stone is recorded and is not treated as a masonry blade when the bullets name wood and sheet goods.
Review outcome
25%UK notes of a straight rip, oak, window ledges, rafters or multi-year table-saw use score up. A UK rejection after a day, and a UK note of about four months of weekly firewood, score down. Non-UK reports of lost carbide are a contents warning, not the UK star line.
Amazon evidence
25%The star line and the review count are read against how many UK texts describe a cut. A 5.0 from five ratings is weaker evidence than a 4.6 from 95. Listings with one, two or zero UK texts sit lower than a larger UK sample.
Shelf price
20%Value uses the GBP shelf price on amazon.co.uk. The lowest price in the set, with the largest review count, is best value. A higher price with a thin review sample does not lead on value. Amazon is not treated as the cheapest UK source.
Match diameter and bore to the saw manual, then plate and kerf to the riving knife, then tooth count to the cut. A 315 mm x 30 mm circular saw blade is a bench disc. A 305 mm mitre blade and a handheld blade are different tools. A star rating is not a substitute for the figures the knife needs.
A 315 mm x 30 mm circular saw blade is a TCT disc for a site or workshop saw bench whose manual specifies that diameter and a 30 mm arbor. In the UK that class includes bench saws such as the Makita 2712 and the Metabo TKHS 315 family. It is not a 305 mm mitre blade and not a handheld blade around 184 mm. You separate the blades by tooth count, kerf, plate thickness, hook and the maximum rpm on the plate, then by whether the listing names wood.
A 305 mm blade is a different disc even when the bore is 30 mm. Read the manual’s diameter, not the inch nickname. A handheld blade around 184 mm is a different class again.
The Makita 2712 manual allows 315 mm and 30 mm, and it limits body thickness to 2 mm or less. A plate field of 2.2 mm conflicts with that line. A loose bush is not the fix. Use only a fixed reducing ring, and only onto a smaller arbor.
The knife should be thicker than the plate and thinner than the kerf, and within 8 mm of the blade at table level. Nailed pallets are a separate risk. Carbide loss after that work is not a surprise, and a cracked body belongs in the scrap bin.
Diameter and bore must match the saw manual: 315 mm and 30 mm. A 305 mm blade stays a different disc when the bore is also 30 mm. HSE wants the riving knife thicker than the plate and thinner than the kerf, and within 8 mm of the blade at table level. For ripping, the knife stays fitted. Where a listing prints a 2.2 mm plate and a 3.2 mm kerf, that pair is the start of the check. Where kerf, hook, plate or maximum rpm are missing from the amazon row, the check cannot start from that page alone.
Tooth count is the cut, not a quality ladder. A coarse count, in this size 24 or 30 teeth, is the rip and breakdown blade. A 48-tooth count is the combination blade for mixed ripping and crosscutting. A 72-tooth or 96-tooth count is the finer crosscut. More teeth are not automatically better, and a five-star line from five ratings is weaker evidence than a larger sample.
Three typical situations, each with a recommendation from this comparison.
You are replacing a disc on a 315 mm bench such as a Makita 2712 or a Metabo TKHS 315. The Trend CSB/31548 is the top pick for mixed ripping and crosscutting, at about £37.00, with a stated 3.2 mm kerf and 4.6 from 95 reviews. The plate field is 2.2 mm, and the Makita 2712 manual limits body thickness to 2 mm or less, so that fit is not settled.
You want one 48-tooth combination blade and a riving knife matched to a 3.2 mm kerf. The Trend CSB/31548 states 48 teeth, a 3.2 mm kerf and a +15° hook. Maximum rpm is not on the amazon listing, so check the speed marked on the plate against the saw before you fit it.
You want the lowest shelf price for rough ripping or firewood, and you do not expect a furniture edge. The BGS 3957 is best value at about £19.03, with 30 teeth, a 3.0 mm cutting width and 4,200 rpm stated. One UK review reports about four months at two hours a week. The details field says Metal, and the bullets do not name wood.
The top pick is the Trend CSB/31548 at about £37.00. It scores 8.8, the highest here: 48 teeth, a stated 3.2 mm kerf and a +15° hook, with 4.6 from 95 reviews, including a UK rip of 50 mm oak. One UK buyer put the old blade back after a day, maximum rpm is not on the listing, and the plate field is 2.2 mm. Best value is the BGS 3957 at about £19.03. It scores 8.2, with 30 teeth, a 3.0 mm cutting width, a 2.2 mm plate, 4,200 rpm stated and 4.5 from 279 reviews. The details field says Metal, the bullets do not name wood, and one UK review reports about four months of weekly firewood.
BGS 3957 carbide blade, 30 teeth
About £19.03 with 4.5 from 279 reviews, 30 teeth and 4,200 rpm stated. The details field says Metal, and one UK firewood note is about four months.
