Rotary Tool Grinding & Sanding Supplies price comparison UK
One glance at this category tells you something interesting: PFERD dominates with over 800 products at an average price well above the rest of the field, whilst Bosch, Dremel and Draper Tools cluster at the affordable end. That split reflects two very different buyer profiles — the professional who needs precision-ground mounted points and vitrified-bond wheels for metalwork, and the hobbyist who just wants a pack of sanding drums to tidy up a DIY project. Both are well served here, with prices ranging from 2 £ up to 36 £.
What catches our attention is how much variety hides behind the label "grinding and sanding supplies". You've got cut-off discs for slicing through plastic and wood, wire brushes for rust removal, sanding bands for curved surfaces, backing pads for hook-and-loop discs, and mounted points for engraving and deburring — all under one roof. The key is knowing which accessory suits your material and your machine. A silicon carbide wheel that's perfect for ceramic tile will glaze over almost immediately on hardened steel; aluminium oxide is the workhorse for general metal and wood, but diamond or CBN is what you reach for when nothing else cuts cleanly.
Compatibility is the most overlooked issue we see. Shank size matters enormously — a 3.17mm (1/8") shank fits most Dremel and Bosch multi-tools, but some PFERD and FEIN accessories use a 6.35mm (1/4") arbor that won't seat in a standard collet without an adaptor. Always check before buying. Similarly, maximum operating RPM is a safety-critical figure, not a suggestion: exceeding it risks wheel disintegration. If you're running a Dremel at 35,000 RPM, your disc needs to be rated for at least that speed.
For accessories that complement your rotary tool setup, it's worth browsing Rotary Tool Polishing Supplies for finishing work, or Rotary Burrs if you need to remove material with more precision than a grinding wheel allows. And if you're working with a larger machine, Angle Grinder Accessories covers the heavier-duty equivalents. The median price across this category sits at 10 £, which tells you that the bulk of the catalogue is firmly mid-range — there's no need to spend at the top of the scale unless your application genuinely demands it.
How to Choose Rotary Tool Grinding & Sanding Supplies
With 973 products in this category spanning everything from a single grinding wheel under 2 £ to specialist PFERD sets approaching 36 £, the choice can feel overwhelming. The good news: most buyers only need to answer three questions — what material am I working on, what finish do I need, and what shank size does my tool take? Get those right and the rest follows.
Abrasive material matched to your workpiece
This is the single most important decision. Aluminium oxide is the go-to for steel, iron and general metalwork — it's tough, self-sharpening and widely available from Bosch and Draper at accessible prices. Silicon carbide is harder and sharper, making it better for stone, ceramics, glass and non-ferrous metals, but it wears faster on steel. For hardened tool steel or carbide, you need diamond or CBN (cubic boron nitride) — these are the PFERD territory, and the price reflects it. Using the wrong abrasive doesn't just give poor results; it causes rapid glazing, heat buildup and can damage your workpiece.
Shank size and collet compatibility
The shank is the cylindrical shaft that fits into your rotary tool's collet, and getting this wrong means the accessory simply won't mount securely. The two most common sizes are 2.35mm (3/32") and 3.17mm (1/8") — the latter fits the vast majority of Dremel, Bosch and Draper multi-tools. PFERD and some FEIN accessories use a 6.35mm (1/4") shank, which requires a separate adaptor unless your tool supports it natively. Check your tool's collet size before ordering, especially when buying mounted points or larger grinding wheels.
Grit size for the finish you need
Grit is the numerical rating of abrasive particle size — lower numbers cut faster and leave rougher surfaces, higher numbers cut slower but produce finer finishes. For aggressive material removal or rust stripping, stay in the 40–80 grit range. General shaping and smoothing sits at 120–220. If you're working up to a polished or painted surface, you'll want 320–400+. A common mistake is jumping straight to a fine grit on a rough surface — you'll burn through discs and get nowhere. Work through the grades progressively.
Maximum RPM rating — a safety-critical spec
Every grinding wheel, cut-off disc and sanding accessory has a maximum operating speed printed on the label or listed in the spec sheet. Never exceed this figure. A disc rated to 25,000 RPM used in a tool running at 35,000 RPM can disintegrate violently, sending fragments at high velocity. Most Dremel and Bosch multi-tools run between 10,000 and 35,000 RPM; check your tool's speed range and match it to the accessory's rating. This is especially important with thin cut-off discs, which are the most fragile type in this category.
Wheel profile and application type
The shape of the wheel or point determines what it's actually useful for. Straight wheels suit flat surface grinding; tapered and conical wheels get into grooves and edges; cup wheels cover larger flat areas efficiently; mounted points — the small abrasive stones on a shank — are for precision deburring, engraving and detail work in tight spaces. Wire brushes and sanding bands are a different category again, suited to surface preparation and contour sanding respectively. Buying the wrong profile for your job wastes both time and money.
Value per disc vs. pack size
Sanding drums, cut-off discs and grinding wheels wear out — that's their job. Buying a single disc at a low headline price can work out more expensive than a multipack if you're doing any volume of work. Draper Tools packs, for instance, offer strong value per unit at the budget end (from 2 £), whilst Bosch multipacks sit in the mid-range and offer consistent quality across the batch. PFERD sells predominantly as individual precision items — justified for professional use, less so for occasional DIY. Factor in how quickly you'll burn through consumables before deciding on pack size.
- Entry-level picks (From 2 £ to 8 £) : Draper Tools and Yato dominate this bracket — individual grinding wheels, single sanding discs and basic wire brushes. Quality is adequate for occasional DIY, but expect shorter working life and less consistent grit sizing. Fine for a one-off job; less economical if you're doing regular work.
- The sweet spot (From 8 £ to 10 £) : Bosch, Dremel and Draper multipacks sit here, alongside Metabo accessories. You get better abrasive consistency, more reliable RPM ratings and wider material compatibility. This is where most hobbyists and light trade users should be spending — good balance of quality and cost per use.
- For regular trade use (From 10 £ to 13 £) : PFERD mounted points, specialist diamond wheels and FEIN accessories start appearing here. Noticeably longer working life, tighter dimensional tolerances and better heat resistance. Worth the step up if you're grinding hardened steel, working to tight tolerances, or using your rotary tool daily.
- Professional and specialist (Over 13 £) : Almost exclusively PFERD and FEIN — precision-ground vitrified bond wheels, CBN mounted points and full accessory sets for industrial applications. The price is justified for production environments or specialist metalwork. For home use, this bracket is overkill unless you have a very specific technical requirement.
Top products
- Draper Tools 99568 rotary tool grinding/sanding supply Grinding wheel (Draper Tools) : The most widely available product in this category and easy to see why — a no-fuss grinding wheel at a price that makes it genuinely disposable. Fine for occasional metalwork; don't expect it to last under heavy use.
- Draper Tools 41427 rotary tool grinding/sanding supply Sanding brush (Draper Tools) : Tied for the most offers in the category. A 50mm wire brush at a budget price — solid for surface prep and rust removal on light metalwork, but the bristle density won't satisfy anyone doing heavy-duty cleaning.
- Bosch 2 608 901 196 rotary tool grinding/sanding supply Plastic, Wood Cut-off disc (Bosch) : Bosch's cut-off disc for plastic and wood is the reliable mid-range choice — consistent thickness, well-rated RPM tolerance, and widely stocked by UK retailers. A sensible buy if you're cutting regularly and want predictable results.
- Dremel Carbon steel brush (Dremel) : Dremel's own-brand carbon steel brush is the natural pairing for any Dremel multi-tool — guaranteed collet compatibility and a noticeably more consistent bristle density than the budget alternatives. Worth the small premium over generic wire brushes.
- Dremel Flexible Shaft (Dremel) : Technically an accessory rather than an abrasive, but it transforms how you use every grinding and sanding attachment in this category — far better control for detail work and engraving. If you do any precision work with a Dremel, this is the one non-abrasive purchase that genuinely changes the experience.

Frequently Asked Questions
What shank size do I need for a Dremel rotary tool?
Most Dremel accessories use a 3.17mm (1/8") shank, which is the standard size for the vast majority of Dremel collets. Some smaller accessories — particularly mounted points and fine engraving bits — use a 2.35mm (3/32") shank, and Dremel tools typically include a collet adaptor for this size. Always check the product listing before buying, as fitting an oversized shank into a collet will damage both the accessory and the tool.
What's the difference between a mounted point and a grinding wheel?
A mounted point is a small abrasive stone permanently bonded to a metal shank, designed for precision work in tight spaces — deburring, engraving, cleaning weld seams. A grinding wheel is a larger, disc-shaped abrasive that mounts via an arbor and is better suited to surface grinding and material removal over a wider area. Mounted points offer more control; grinding wheels remove material faster. PFERD specialises in mounted points, which explains their higher average price in this category.
Can I use angle grinder discs on a rotary tool?
No — this is dangerous and should never be attempted. Angle grinder discs are designed for tools running at much lower RPM with a different arbor system. Fitting one to a rotary tool running at 25,000–35,000 RPM will almost certainly cause the disc to shatter. Always use accessories specifically rated for rotary tools and check that the maximum RPM on the accessory meets or exceeds your tool's top speed.
How do I know when a grinding wheel needs replacing?
Replace a grinding wheel when you notice glazing (the surface looks shiny and smooth rather than gritty), excessive vibration, uneven wear, or any visible cracks or chips. Glazing means the abrasive particles have become dull and the wheel is generating heat rather than cutting — continuing to use it risks workpiece damage and can cause the wheel to break up. A wheel that's worn down to a small fraction of its original diameter should also be retired, as the reduced mass affects balance and RPM safety ratings.
Are cheap own-brand grinding wheels worth buying, or should I stick to Bosch and Dremel?
For occasional DIY, Draper Tools wheels are genuinely decent value — they're the most widely stocked budget option in this category and hold up fine for light use. Where cheaper wheels fall short is consistency: grit sizing can vary within a batch, and maximum RPM ratings are sometimes optimistic. For regular use on metal or hardened materials, Bosch and Dremel accessories offer more reliable performance and better safety margins. Yato is the budget outlier — fine for very light work, but we wouldn't rely on them for anything structural.
What grit should I start with for removing rust from metal?
Start with a 60–80 grit aluminium oxide wheel or sanding band for heavy rust removal — this cuts through oxidation quickly without loading up. Once the surface rust is gone, step up to 120 grit to smooth the surface, then 220 if you're preparing for paint or primer. Using a wire brush attachment first can help knock off loose scale before you start with abrasives, which extends the life of your grinding wheels considerably.
Is PFERD worth the premium over Bosch or Dremel for home use?
Rarely, unless you have a specific professional application. PFERD's mounted points and vitrified bond wheels are engineered for precision metalwork, production grinding and hardened materials — their quality is genuinely exceptional, but the price reflects industrial-grade tolerances that most home users simply don't need. For the vast majority of DIY and light trade work, Bosch and Dremel accessories deliver excellent results at a fraction of the cost. Save the PFERD budget for when you're working on hardened steel, carbide, or need consistent results across hundreds of pieces.
