The best rasp discs, compared.
Top pick: OBA OGD17 – Highest score: 4.5 from 1,558 reviews at £13.99, with 115 mm, a 22.23 mm bore, 12,000 rpm and carbon steel stated in the table. Best value: Techfection 125 mm set – Three 125 mm discs at £13.59, 40 pence under the single OBA disc, with 4.5 from 245 reviews. No maximum speed is printed. Updated October 2026.
A rasp disc is a toothed shaping wheel for an angle grinder. You use it for carving, rounding, stripping bark, and levelling before sandpaper. It is not a bonded grinding wheel, not a flap disc, and not a chainsaw-style or large toothed saw blade. Product safety alerts treat those saw attachments as a serious kickback risk. Most are 100 mm, 115 mm or 125 mm carbide or carbon-steel wheels. If the disc stands proud, leave the guard on. Check the bore and a maximum speed in rpm. How to choose is set out in the [rasp disc buying guide](/hub/sanders/rasp-disc/sub/rasp-disc-buying-guide).

Question 1 of 2
What guard is on the grinder?
The OBA OGD17 is a single 115 mm carbon-steel carving disc at £13.99, listed at 210 g with a stated 22.23 mm arbor and a maximum of 12,000 rpm. amazon.co.uk shows 4.5 from 1,558 reviews in this capture. Titles praise stock removal, and one of them adds that the disc is not very surgical. Another title says to use it with care, one title calls it dangerous to use, and another says it was useless after one use. The box list includes an inner diameter ring, the page cites EN 847-1, and the bullets warn that a nail at 12,000 rpm will damage the teeth. A bullet claims the size fits every angle grinder, while the compatible-devices line names 115 mm and 125 mm tools, so you match the guard rather than the slogan. It is the top pick in this set when you want one widely reviewed 115 mm wheel, and a poor fit on a 100 mm guard or when you need several profiles in the box.
Pros
Cons
Best for: A 115 mm angle grinder when you want one carbon-steel shaping disc with a large UK review count and a stated bore.
Less suitable: A 100 mm guard, fine detail carving, or a job that needs several disc profiles in one pack.
Specifications
Common questions
Which grinder size matches the OBA OGD17?
The listing states 115 mm diameter. Match the guard to that size. A bullet that says the disc fits every angle grinder clashes with a devices line that names 115 mm and 125 mm tools.
What material are the teeth?
The listing lists carbon steel. The page also cites EN 847-1 and includes an inner diameter ring. That citation is the page text, not a lab result from this comparison.
What maximum speed is printed?
The listing shows 12,000 rpm. Do not exceed the lower of the disc mark and the grinder rating. The bullets warn that a nail at that speed will damage the teeth.
The Techfection listing is a three-piece 125 mm set at £13.59 and 1.03 kg, with 22 mm in the title and no maximum speed in the specification. amazon.co.uk shows 4.5 from 245 reviews, and praise titles call the wheels durable. UK review text also says one buyer received two discs instead of three, and that the wheels are heavy and out of balance. Compatible materials run beyond wood to plastic, rubber, styrofoam and plasterboard, so the page is wider than a timber-only carving disc. Pack lines disagree slightly: number of items is 3 while included components prints 1. At 40 pence under the single OBA disc you receive three 125 mm wheels, which is why this is the best value line if your guard is 125 mm. It is the wrong diameter on a 115 mm or 100 mm guard, and you cannot compare rpm with the grinder because that field is blank.
Pros
Cons
Best for: A 125 mm guard when you want three shaping discs and can accept a listing with no printed rpm.
Less suitable: 100 mm or 115 mm grinders, or any buy where you need a stated maximum speed before you mount the disc.
Specifications
Common questions
Which grinder size matches the Techfection set?
The listing states 125 mm diameter. Match the guard to that size. It does not belong on a 115 mm or 100 mm guard. The title states a 22 mm arbor; the bore cell in the specification is blank.
What material are the teeth?
The material field lists carbon and carbon steel. Compatible materials on the page also include plastic, rubber, styrofoam and plasterboard, so this is wider than a timber-only carving disc.
Pomsare W115C is a four-piece 115 mm set at £28.49 and 980 g, with a stated maximum of 12,200 rpm and grit number 60. The bullets describe flat, curved and inclined discs in carbon steel, while the title says tungsten carbide, so the material is not one story on this page. amazon.co.uk shows 4.4 from 177 reviews. Praise titles mention timber grinding and carving. One title says poor quality that did not last, and another says only use once. The title also names an M14 thread and a 22.23 mm arbor, which you still check against your spindle. At more than double the price of the single OBA 115 mm disc, the set earns its place only when you will use those extra profiles. It is a weak buy if you wanted one flat disc and a single agreed material.
Pros
Cons
Best for: A 115 mm grinder when you want flat, curved and inclined profiles and can live with the material clash.
Less suitable: A single flat disc on a budget, a 100 mm guard, or a buyer who needs the title and the table to name the same metal.
Specifications
Common questions
Which grinder size matches the Pomsare W115C?
The listing states 115 mm diameter. Match the guard to that size. The title also names an M14 thread and a 22.23 mm arbor, which you still check against the spindle.
What material are the teeth?
The material field lists carbon steel. The title says tungsten carbide. Read both lines. The bullets name flat, curved and inclined discs.
What maximum speed is printed?
The listing shows 12,200 rpm. Do not exceed the lower of the disc mark and the grinder rating. Grit number 60 is on the specification.
The EJUXPSE SL003 listing is £10.99 and 300 g. The title calls it a three-piece 4 inch (100 mm) tungsten-carbide set, while the specification lists the number of items as 1. amazon.co.uk shows 4.0 from 13 reviews. Titles praise aggressive wood removal and shaping, and one buyer with a Makita says only one of the three discs fitted. No maximum speed and no bore are printed, so you cannot compare rpm with the grinder from this page. At this price it is the budget 100 mm option that at least has a few removal comments, though thirteen reviews is a thin sample next to the OBA’s 1,558. It suits a 4 inch grinder for rough shaping if you accept the pack-count clash. It is the wrong row when you need a stated rpm or a 115 mm guard.
Pros
Cons
Best for: A 4 inch grinder for rough shaping when you accept a thin review sample and a pack-count clash.
Less suitable: A 115 mm guard, or any purchase that depends on a printed bore and rpm.
Specifications
Common questions
Which grinder size matches the EJUXPSE SL003?
The title says 4 inch (100 mm). Match a 4 inch guard to that size. The specification lists the number of items as 1 while the title says three pieces.
What material are the teeth?
The listing lists tungsten carbide, and that wording agrees with the title. No bore and no maximum speed are printed on the captured specification.
YUXNVI YX10006 is listed at £12.99 and 710 g. The title describes a four-piece 4 inch tungsten-carbide set with flat, bevel and arc profiles plus 75 mm discs. The specification disagrees: diameter 46 mm, aluminium oxide, grit 46, and EN 12413 in the identifier field. That standard line is not a certificate you can treat as proved by the web page. Recommended uses include metal fabrication and rust removal as well as wood. Maximum speed is printed as 13,300 rpm. amazon.co.uk shows 2.0 from two reviews: one says the discs are not sharp enough, and the other says two of them wore out quickly on a wooden bench. The manufacturer field says YUXINWAY while the brand field says YUXNVI, so resolve the title and the table before you fit anything to a guard.
Pros
Cons
Best for: Only a buyer who can inspect the discs and ignore the title where it clashes with the 46 mm aluminium-oxide line.
Less suitable: Anyone who needs a confirmed 100 mm carving disc, or who would treat EN 12413 on the listing as certification.
Specifications
Common questions
Which grinder size matches the YUXNVI YX10006?
The diameter field says 46 mm. The title says 4 inch and also mentions 75 mm discs. Those lines do not agree. Do not fit the disc until you have measured it against the guard.
What material are the teeth?
The material field lists aluminium oxide. The title says tungsten carbide. EN 12413 on the page is not a bonded-wheel certificate in your hand.
What maximum speed is printed?
The listing shows 13,300 rpm. That figure sits beside a diameter field that clashes with the title, so do not treat the speed as settled. Do not exceed the lower of a confirmed disc mark and the grinder rating.
ChongYue CYSGJMPA is the cheapest line in the set at £6.89, sold as a three-pack with tungsten-carbide teeth for wood and plastic. The diameter field is blank, the dimensions read 10 × 10 × 0.1 centimetres, thickness is 0.3 centimetres, and the weight is 25 g, which is very light for three discs. Maximum speed is printed as 13,300 rad/sec. That is not an rpm figure you can set against a grinder nameplate. Included components says no. The only UK review is 2.0 stars: the buyer says the disc sticks out and they could not use it. The bullets claim a fit for most standard 4 inch grinders without extra adapters, which the empty diameter and bore fields do not support. It is a trial only if you can return a pack that will not mount, and a poor choice when you need a stated diameter and a usable speed mark.
Pros
Cons
Best for: A returnable trial on a 4 inch grinder if you will reject the pack when bore or guard does not match.
Less suitable: Any job that needs a stated diameter, a real rpm mark, or more than one buyer report.
Specifications
Common questions
Which grinder size matches the ChongYue CYSGJMPA?
The diameter field is blank. Bullets describe a 4 inch grinder, and the only UK review says the disc sticks out and could not be used. Match the guard to the disc you can measure, not to the slogan.
What material are the teeth?
The specification lists tungsten carbide, for wood and plastic. Stated weight is 25 g, and the included-components line reads no.
What maximum speed is printed?
The listing prints 13,300 rad/sec. That is not rpm, and you cannot set it against the grinder nameplate. Do not treat it as a disc speed mark.
DVDVBOOM’s listing is £15.99 for a kit the title describes as five wood carving discs plus five rotary burrs, for 4 inch or 4.5 inch grinders, with a 5/8 inch adapter claimed in the comparison fields. The specification instead prints a 4 inch diameter, carbon steel, 200 g, and no maximum speed. Number of items is 1 while included components says 5 pcs, and the title’s tungsten-carbide wording does not match the carbon-steel field. This amazon.co.uk capture has no star rating and no review text, so nothing here confirms fit or how long the teeth last. A 200 g line for a ten-piece kit is light enough that the contents are unresolved until the parcel arrives. Consider it only if you can verify bore and rpm on the physical 4 inch discs. Skip it when you wanted reviewed 115 mm wheels or a stated speed mark.
Pros
Cons
Best for: A buyer who specifically wants a 4 inch disc-and-burr kit and will check bore and rpm on the discs in the box.
Less suitable: Anyone who needs reviews, a stated rpm, or a resolved 115 mm fit before ordering.
Specifications
Common questions
Which grinder size matches the DVDVBOOM kit?
The specification states 4 inches. The title also says 4 inch or 4.5 inch grinders. Match the guard to the disc you measure. This capture has no star rating and no review text.
What material are the teeth?
The material field lists carbon steel. The title says tungsten carbide. Number of items is 1 while the title describes five discs plus five burrs, and included components says 5 pcs.
Seven amazon.co.uk rasp and carving discs were scored from the listings in the 20 October 2026 capture. Weights sum to 100. Star ratings, review counts and review themes come from those amazon.co.uk listings. There was no lab test. A listing with no star line scores 0 rather than a score built from catalogue points alone.
Amazon stars
40%Star rating scaled to 40 points: stars divided by 5, times 40, rounded to the nearest integer. A listing with no star line scores 0 on this block.
Review depth
20%Review count scaled to 20 points. No reviews score 0. One review scores 3. Bands then run through 2–12, 13–49, 50–199, 200–999, and 1,000 or more at the top of the block.
Listing fit
20%Up to 20 points for a diameter that matches the title, a stated bore, a maximum speed in rpm, and a material field that agrees with the title. A blank speed, a rad/sec figure, or a bore that appears only in the title scores less.
UK review sentiment
20%Up to 20 points for how often UK review text describes a finished wood job, set against kickback, early bluntness, missing pieces, or a disc that would not mount. An item count that contradicts the title is a separate deduction.
Check the guard size first, then the bore and a maximum speed in rpm, then whether the listing is a carving disc rather than a chainsaw or toothed saw attachment. Seven amazon.co.uk listings were scored from the 20 October 2026 capture. There was no lab test. A star line from one or two reviews does not equal one from more than a thousand.
A rasp disc on an angle grinder is a toothed shaping wheel for rapid wood stock removal. You use it for carving, rounding, stripping bark, and levelling a surface before sandpaper. It is not a bonded abrasive grinding wheel, and it is not a flap disc. It is also not the chainsaw-style disc or the large toothed saw-blade attachment that GOV.UK product safety alerts PSA2 and PSA5 say must not be used on an angle grinder.
A 115 mm disc on a 100 mm guard stands proud. Taking the guard off is not the fix. Match 100 mm to a 4 inch guard, and 115 mm or 125 mm to the matching guard.
The disc has to sit flat on the inner flange with the lock nut fully engaged. UK reviews in this set include a Makita owner who could fit only one of three discs, and a buyer whose disc stuck out.
A chainsaw disc or a large toothed saw blade is not a rasp disc. GOV.UK alerts say those attachments must not be used on an angle grinder. Skipping eye protection because the job is only wood is the same class of mistake.
A 100 mm disc belongs on a 4 inch guard. A 115 mm or 125 mm disc belongs on the matching guard. If the disc stands proud, leave the guard on and change the disc. In this set OBA and Pomsare are 115 mm, Techfection is 125 mm, and the EJUXPSE title says 4 inch (100 mm). YUXNVI’s diameter field says 46 mm against a 4 inch title, so that row is unresolved until you measure the disc. The disc must sit flat on the inner flange with the lock nut fully engaged. OBA and Pomsare state 22.23 mm.
Choose a purpose-made carving or rasp disc. Do not buy a chainsaw disc or a large toothed saw blade for an angle grinder. GOV.UK alerts PSA2 and PSA5 treat those attachments as a serious kickback risk. A carbide or carbon-steel carving disc is not that class, and it is not an official approval of the teeth. The disc can still snag and throw chips. Tungsten-carbide teeth cut wood quickly. Carbon steel is the other pattern in this set, including the OBA disc.
Three typical situations, each with a recommendation from this comparison.
You want a 100 mm set to trim a sticking door or knock back rough timber. The EJUXPSE SL003 title says 4 inch (100 mm) tungsten carbide at £10.99, with 4.0 from 13 reviews. One Makita review says only one of three discs fitted, and no bore or rpm is printed.
You want curved and inclined profiles and you accept aggressive removal. Pomsare W115C is four 115 mm discs at £28.49, with 4.4 from 177 reviews and a stated 12,200 rpm. The title says tungsten carbide and the material field says carbon steel.
You want one 115 mm wheel with the deepest UK review file in this set. The OBA OGD17 is £13.99, with 4.5 from 1,558 reviews, a 22.23 mm arbor and 12,000 rpm. It is a single disc, and some review titles call it dangerous or useless after one use.
The top pick is the OBA OGD17 at £13.99, with 4.5 from 1,558 amazon.co.uk reviews and the highest score in this set. The table states 115 mm, a 22.23 mm bore, 12,000 rpm and carbon steel. It is one disc, and review titles include harsh warnings. The best value is the Techfection 125 mm three-piece set at £13.59, with 4.5 from 245 reviews, 40 pence under that single disc, and no printed maximum speed. There was no lab test.
