The best 250mm x 30mm circular saw blades, compared.
Top pick: Saxton 250 mm 100T negative rake Best value: Tech Traders 250 mm 80T – Lowest single-blade price that still prints a 30 mm bore, 80 teeth and a 2.6 mm kerf. Updated October 2026.
A 250mm x 30mm circular saw blade is a carbide-tipped disc for a table saw, mitre saw or radial-arm saw whose manual states that diameter and a 30 mm arbor. Seven amazon.co.uk listings stayed after discs of other diameters were set aside. Check a stated bore, a kerf and a plate the riving knife can sit between, a speed you can compare with the saw, and a UK review file for that job. Only the cheapest pair prints a maximum speed. Nothing was cut in a laboratory, and none of the listings states BS EN 847-1. Matching bore and diameter is covered in [how to match saw blade bore and diameter](/hub/saw-accessories/blog/how-to-match-saw-blade-bore-and-diameter). Shoppers are replacing a blade, not buying the saw.

Question 1 of 2
What are you cutting?
The Saxton TCTNR250100T is a 250 mm, 100-tooth blade with a 30 mm bore and a stated rake of -5 degrees, at £22.99 and rated 5.0 from 5 reviews. Kerf is 2.6 mm, plate is 1.8 mm, and weight is 780 g. The components line includes 16, 20 and 25 mm rings, while the title also names a 25.4 mm ring. No rpm is printed. The bullets aim it at coated and veneered board and name mitre, chop, table, handheld, and radial-arm saws. Three UK texts were captured. One says laminate cut smoothly, one says the size and tooth count were right but the blade has not been tried, and one compares it with dearer blades without detail. Five ratings are too few to treat as a life test.
Pros
Cons
Best for: Controlled cuts in laminate and veneer on a mitre or radial-arm saw that takes 250 mm and 30 mm, if a thin review file is acceptable.
Less suitable: A buyer who wants a large UK review file, a confirmed 25.4 mm ring, or a fast rip in nail-risk timber.
Specifications
Common questions
What rake does this Saxton blade state?
The bullets print -5 degrees. They describe a slower cut with less feed pressure and a reduced kickback tendency. That is a listing claim, not a lab result.
Does it include a 25.4 mm ring?
The title names a 25.4 mm ring. The bullets and the included-components line name 16, 20 and 25 mm only.
How should the 5.0 rating be read?
The listing shows 5.0 from 5 ratings. Three UK texts were captured, and one says the blade has not been tried. That is not a durability result.
The DeWalt DT1957-QZ is titled as a 250 mm x 30 mm 48-tooth nail-tough circular saw blade at £20.79, with 4.7 from 2,566 ratings. The teeth attribute says 40, and the dimensions cell says 25.4 by 25.4 cm, so both conflicts stay visible. Item thickness is 1.8 mm and weight is 921 g. Kerf, rake, and rpm are not printed, and the material cell says Shell. Included components name one blade and no reduction rings. The listing claims ribbed heat vents, C2 carbide, a thin kerf, and an anti-stick coating. UK reviews describe clean cuts in hardwood and several nail strikes in reclaimed timber. One DIY buyer said two blades went blunt early, and one kitchen fitter measured life in about three jobs of cornice, pelmet, and plinths.
Pros
Cons
Best for: Stationary saws that take a 250 mm x 30 mm blade when the timber may contain nails and you can live with the 40-versus-48 conflict.
Less suitable: A smaller arbor that needs a ring, or a fine veneer cut that wants a stated negative rake.
Specifications
Common questions
Is the DeWalt DT1957 a 48-tooth or a 40-tooth blade?
The title and the included-components line say 48 teeth. The teeth attribute says 40. Both figures are kept.
Does it include reduction rings?
No. Included components name one 250 x 30 mm blade and do not list rings. One UK review wished a reducer had been included.
What do UK reviews say about nails?
Several UK accounts describe nail strikes in reclaimed wood or floorboards with the blade still cutting. One DIY buyer says two blades went blunt early, and one kitchen fitter says a blade lasts about three jobs.
The Saxton TCT250100T is a 250 mm x 30 mm 100-tooth blade at £21.99, rated 4.7 from 396 reviews. It states a positive cutting angle, ATB teeth, a 2.6 mm kerf, a 1.8 mm plate, and rings for 16, 20 and 25 mm. Weight is 740 g. No maximum speed is printed. UK reviews describe a clean face on plywood, MDF, laminated MDF, and oak, including one blade used for laminate flooring and then a 7 by 3 metre deck. One buyer replaced a stock 255 mm 40-tooth blade on a Rutlands table saw and called the result more precise. A few texts say it is too early to judge how long the edge lasts, so life beyond those jobs is not measured.
Pros
Cons
Best for: A fine finished edge on plywood, MDF, and hardwood on a table or chop saw that takes 250 mm and 30 mm.
Less suitable: Timber that may hide nails, or a mitre saw where you specifically want the -5 degree rake.
Specifications
Common questions
How does this 100 tooth blade differ from the negative-rake Saxton?
This listing states a positive cutting angle. The negative-rake sibling, B0FJ2JM23C, prints -5 degrees. Both state 100 teeth, a 2.6 mm kerf, and a 1.8 mm plate.
What did UK reviews say about the finish?
Reviews describe little breakout on plywood, MDF, laminated MDF, and oak, including 12 mm oak bevels with no burning in one account. One blade was used for laminate flooring and then a deck.
Is a maximum speed printed?
No. Rpm is not in the extract, so speed compatibility with the saw is unchecked.
The Saxton TCT25080T is a 250 mm x 30 mm 80-tooth blade at £19.99, rated 4.6 from 1,837 reviews. It states ATB teeth, a positive cutting angle, and a kerf of 2.6 mm, with rings for 16, 20 and 25 mm. Plate thickness and rpm are not in the extract. The weight cell prints 49.9 g and is kept as written. The title says the blade fits 255 mm saws, and one UK review says the missing 5 mm left the cut short of the deck groove. UK reviews often describe a cleaner edge than a stock blade on table saws and chop saws. One tooth failed or was missing on an MDF skirting cut, and one Clarke owner was caught by rated speed because no rpm number is printed.
Pros
Cons
Best for: A widely reviewed 80-tooth positive-rake blade for softwood, hardwood, plywood, and MDF on a saw that takes 250 mm and 30 mm.
Less suitable: A 255 mm saw that must reach a deck groove, or a job that needs a printed maximum speed.
Specifications
Common questions
What rings come with the Saxton 80 tooth blade?
The listing includes 16, 20 and 25 mm reduction rings for the 30 mm bore.
Will a 250 mm blade reach the groove on a 255 mm saw?
The title says it fits 255 mm saws. One UK review says the missing 5 mm left the cut short of the deck groove. That is one account, not a general clearance.
What does the weight cell say?
The attribute prints 49.9 g. It is kept as written and is not treated as a corrected weight.
The Toolzone PA026 is a pair of 250 mm TCT circular saw blades, one with 40 teeth and one with 60 teeth, listed at £11.57 on amazon.co.uk with 4.6 from 531 ratings. The listing prints a maximum of 6,000 rpm and does not state the bore, the kerf, or the plate thickness. UK reviews describe the plates as thin, including one Erbauer chop saw that would not tighten the blade and one case where the riving knife would not pass. Some buyers mention spacers or reducing rings, but the included-components cell does not name them. The pair is the lowest shelf price in this set. It suits scrap, pallets, and general DIY only after you confirm the bore on the saw, because this page never prints it.
Pros
Cons
Best for: A cheap 40-tooth and 60-tooth pair for scrap and general DIY, once you have checked the bore yourself.
Less suitable: Anyone who needs a stated 30 mm bore, a printed kerf, or a plate that must clear a riving knife.
Specifications
Common questions
Does the Toolzone PA026 state a 30 mm bore?
No. The title is 250 mm and the bore is not in the specification block. A 2021 UK review says the description failed to state bore and kerf.
What speed is printed on the Toolzone pair?
The listing prints a maximum of 6,000 rpm. That is the only speed mark in this comparison set.
What did UK reviews say about the plates?
Several UK reviews call the plates thin. One Erbauer chop saw would not tighten the blade, one mitre saw slipped, and one user could not pass the riving knife and removed it.
The DeWalt DT1963-QZ is a three-blade 250 mm construction pack at £49.59, rated 4.6 from 486 reviews. The components line says 250 x 30 mm x 24T/48T, the teeth cell says 48, and the third tooth count is not printed. A bullet says a universal 1/2 inch shank, which conflicts with the 30 mm line. Item thickness is 2 mm and the pack weighs 1.43 kg. Kerf, rake, and rpm are not printed, and the material cell says Wood. The highlight claims nail-tough carbide and ribbed heat vents. Most of the first 50 reviews are not labelled United Kingdom, so they are not treated as UK opinion. The few UK texts call the blades genuine and a fair price, and one buyer says the next set will be 305 mm because this diameter was the wrong follow-up for that saw.
Pros
Cons
Best for: A stationary saw that takes 250 mm and 30 mm when you want a construction pack and can ignore the 1/2 inch bullet.
Less suitable: A 1/2 inch arbor, a 305 mm saw, or a buyer who needs a UK-heavy review file.
Specifications
Common questions
How many blades are in the DeWalt DT1963 pack, and what tooth counts are printed?
Number of items is 3. The components line says 24T/48T. The third tooth count is not printed, and the teeth attribute says 48.
Is the bore 30 mm or 1/2 inch?
The components line says 250 x 30 mm. A bullet says universal shank 1/2 inch. Those two figures are not reconciled.
Are the 486 reviews a UK file?
Most of the first 50 texts are labelled Belgium, France, the Netherlands, Germany, Sweden, or Spain. The few UK texts call the blades genuine and fair value. One UK buyer says the next set will be 305 mm.
The Tech Traders TT250MM80T30MM is a 250 mm x 30 mm 80-tooth blade at £13.99, rated 4.6 from 22 reviews. It states ATB teeth, a positive cutting angle, a 2.6 mm kerf, and rings for 16, 20 and 25 mm. The stated weight is 499 g. Plate thickness and maximum speed are not printed. The title says it fits 255 mm saws, and none of the seven UK texts tests that claim. One retired wood machinist describes a fine cross-grain cut with a waste piece behind the cut. The sample is too small for a life claim, and the geometry is close to the Saxton 80 tooth blade at a lower single-blade price.
Pros
Cons
Best for: A low-priced 80-tooth positive-rake blade when the saw takes 250 mm and 30 mm, or 16, 20 or 25 mm with the supplied rings.
Less suitable: A buyer who needs a printed plate thickness, a printed rpm, or a large UK review file.
Specifications
Common questions
Which reduction rings come with the Tech Traders 80 tooth blade?
The bullet lists 16, 20 and 25 mm reduction rings with the 30 mm bore.
Does the listing print a maximum speed?
No. Rpm is not in the extract, and there is no standard mark.
How large is the UK review file?
The listing shows 4.6 from 22 ratings. Seven UK texts were read. One describes a fine cross-grain cut. None tests the title line that it fits 255 mm saws.
For this comparison we read seven amazon.co.uk listings that state 250 mm, after other diameters were set aside, plus the public UK sources below. The score on each row is the amazon.co.uk star line times 20. That figure is not a laboratory result, and a high star line on five ratings does not by itself decide the top pick.
Diameter and bore
25%The blade has to be 250 mm with a stated 30 mm bore, or a named ring for a smaller arbor. A listing that omits the bore is not treated as a 30 mm fit.
Kerf and plate
20%A riving knife needs a plate thinner than the knife and a kerf thicker than the knife. Both numbers have to be printed before that check is possible.
Tooth count
20%Fewer teeth suit construction and nail-risk timber. 80 and 100 teeth suit a finer face on wood and board. Conflicting tooth cells are left as printed.
Rake
15%A positive angle is the general fine-wood cut. A printed negative rake is the slower cut aimed at mitre saws and coated board. Blank rake stays blank.
Speed and review sample
20%A printed maximum speed can be compared with the saw. A plate that will not clamp, and a five-rating sample, are reasons to hold back.
Match diameter and bore to the saw manual first. Tooth count, rake and price only matter after the blade can actually go on the arbor and clear the riving knife.
A 250 mm x 30 mm circular saw blade is a carbide-tipped disc for a UK table saw, mitre saw or radial-arm saw whose manual states that diameter and a 30 mm arbor. Shoppers in this set are replacing a blade, not buying the saw. Fit comes before tooth count and rake. Seven amazon.co.uk listings remained after five other files were dropped because they were 210 mm, 300 mm, 255 mm, 190 mm or 254 mm. Nothing here was cut in a laboratory. Diameter and bore are the first check.
The Toolzone pair never prints a bore. A 250 mm title is not a 30 mm arbor. Confirm the saw, or buy a listing that states 30 mm.
One UK review of a 250 mm blade on a 255 mm saw left the cut short of the deck groove. One manual can allow 250 mm on a saw whose name says 254. Read that manual. Do not average the sizes.
A thin plate that will not pass the knife is a reason to reject the blade. Taking the knife off is not a fix. If the guard or the knife cannot be set, stop and call a professional.
Diameter and bore decide whether the blade can go on the saw. The manual has to allow 250 mm, and the arbor has to be 30 mm, or the listing has to name a ring for a smaller arbor. Six of the seven listings print 30 mm. The Toolzone PA026 pair at about £11.57 does not, and a UK review said the description left bore and kerf out. This page does not invent a bore for it. Tech Traders and the three Saxton blades include 16, 20 and 25 mm rings.
The riving knife has to be thicker than the plate and thinner than the kerf, and within 8 mm of the blade. That is the Health and Safety Executive position for a rip saw. You can check it only when both numbers are printed. Both Saxton 100-tooth blades state a 1.8 mm plate and a 2.6 mm kerf. The Saxton 80-tooth and the Tech Traders 80-tooth state a 2.6 mm kerf and no plate. The DeWalt listings and the Toolzone pair state neither.
Three typical situations, each with a recommendation from this comparison.
You want a finer face than the stock blade on plywood, MDF or hardwood, and the saw takes 250 mm and 30 mm. Read the bore and the kerf before the star line. The Saxton 100-tooth blade prints both a 2.6 mm kerf and a 1.8 mm plate.
You are closer to a construction blade than to a 100-tooth finishing blade. The DeWalt DT1957 states a nail-tough claim for stationary saws at about £20.79. The title says 48 teeth and the attribute says 40, so both figures stay visible.
Coated board and veneer on a mitre or radial-arm saw are the job for a negative rake. Only the Saxton 100-tooth negative-rake blade prints one, at -5 degrees. Five ratings, including one unused blade, are a thin file.
For a fine edge on a saw that takes 250 mm and 30 mm, the top pick is the Saxton TCT250100T. It prints a 2.6 mm kerf, a 1.8 mm plate, a positive rake and 100 teeth, at about £21.99 with 4.7 from 396 reviews. It does not print a maximum speed. The best value is the Tech Traders 80-tooth blade at about £13.99, with a stated 30 mm bore, a positive rake and a 2.6 mm kerf, on 22 reviews. If the timber may hide nails, the DeWalt DT1957 is the construction listing, and you have to live with a title that says 48 teeth and an attribute that says 40.
Tech Traders 250 mm 80T
Lowest single-blade price that still prints a 30 mm bore, 80 teeth and a 2.6 mm kerf.
