Best Rotary Tool Accessory Kits in 2026: Dremel Cutting Wheels, EZ Lock Sets and Multi-Piece Kits Ranked by Owners

This 44-piece set is the budget assortment that more than thirteen thousand owners have reviewed, with a strong rating, and it earns that by covering jobs Dremel’s metal wheels do not. Inside are three disc types: resin cut-off discs for thin metal, plastic and circuit boards, high-speed steel circular saw blades in six diameters from 22 to 50 mm for wood, plastic and soft metal, and diamond-coated wheels for tile, glass, gem and stone, plus the mandrels to mount them and a box to keep them in. For hobby work, model making, jewellery and the odd household job it is remarkable value. The caveats are real. Resin discs are thin and will fly apart if you lever them in a cut, HSS saw blades can grab and kick on a hand-held tool, so use them slowly and lightly, and the finish is not Dremel’s. Wear glasses, respect the speed limits, and it is a fine box of bits.

SpeedClic is what Dremel calls EZ Lock in Europe, and the 456B is the twelve-wheel refill for either mandrel: 38 mm fibreglass-reinforced metal cutting discs on the 3.2 mm quick-change system, so they drop onto an EZ402 or SC402 mandrel with the same pull, click, twist. Thousands of owners rate them highly, and the praise is for the thing that separates genuine Dremel wheels from the assortments: every disc is the same thickness and runs true, so a cut through a bolt or a stuck exhaust clamp goes the way you aimed it. The name trips people up, since Amazon lists it under the SpeedClic branding while the mandrel in most US toolboxes says EZ Lock, but they are the same fitting. There is no mandrel in the box and these are metal wheels only, so pair them with the EZ406 starter kit or an EZ402. For anyone who has used up their first five wheels, this is the refill.

The EZ456B is the US-branded twin of the 456B above, twelve EZ456 wheels for the EZ Lock mandrel, and it carries one of the best owner ratings on this page from thousands of reviews. The wheels are 1-1/2 inches across and 0.045 inch thick, reinforced with fibreglass so they take the side load of a hand-held cut without shattering, and Dremel rates them to last twice as long as its old 426 wheels. They cut, groove and trim hardened steel, bolts, screws and sheet metal, and will handle thin wood and ceramic in a pinch. Changes take seconds on the EZ402 mandrel, which, as with every EZ Lock wheel, you buy separately or get in the starter kit. Owners who do a lot of bolt trimming, lock work or car repair tend to buy this pack twice a year. You pay a premium per wheel over the budget resin discs, and there is nothing here for tile or glass, but for metal work with a Dremel these are the wheels to have.

The EZ728-01 is the kit for someone who wants one Dremel box that covers metal, plastic and fine work. It includes the EZ402 EZ Lock mandrel, four EZ456 reinforced metal wheels, three EZ409 thin-cut wheels for precise, narrow kerfs in metal, and three EZ476 wheels designed for plastic, which cut without melting the edge the way a metal wheel does on PVC or acrylic. All eleven pieces live in a reusable case with a slot for each, which sounds trivial until you have hunted a loose wheel in a toolbox. Thousands of owners rate it highly, and the EZ476 plastic wheels are the piece people say they did not know they needed. It is still a small kit that a weekend of cutting will deplete, there is nothing for tile or glass, and it costs more than the starter kit for the extra variety. As a tidy, complete Dremel cutting box, though, it is the best one the company sells.

If the job in front of you is tile, glass, slate or a stone countertop edge, the 44-piece set’s handful of diamond discs will not last, and this 26-piece kit is the answer: ten diamond-coated cutting wheels, which the maker positions as replacements for Dremel’s EZ545 and EZ544 diamond discs, alongside ten resin cut-off discs for metal and plastic and six HSS circular saw blades from 22 to 50 mm for wood and soft metal, with mandrels and a box. Thousands of owners rate it highly, and tile trimming and glass bottle cutting are the jobs that come up most. The maker says it was tested on genuine Dremel tools and the mandrels fit die grinders too. The resin discs are as thin as any budget disc and want a straight, light cut, and the HSS blades will grab if you force them. Pair it with a Dremel metal pack for the heavy steel work, and this covers everything else.

Before EZ Lock there was the 426, and plenty of rotary tools still carry the 402 screw mandrel it fits. The 426B gives you twenty genuine Dremel fibreglass-reinforced wheels, 1-1/4 inches across and 0.045 inch thick, for slicing hard and soft metal, marble, drywall and plastic; the smaller diameter is actually an advantage in a tight engine bay or inside a cabinet where a 1-1/2 inch wheel will not fit. Owners give it an excellent rating and buy it because twenty Dremel wheels for the price is good value and because they already own the mandrel. The compromises are the old system itself: changing wheels means a screwdriver and a tiny screw that lands in the sawdust, and Dremel rates the 426 at half the life of the EZ456. The Amazon listing refers to the EZ402 mandrel, but the 426 is a screw-mount wheel for the 402, so check which mandrel you have. For existing screw-mandrel users, it is the pack.

If you do not own a rotary tool yet, the HARDELL kit is the sensible way in: a 180-watt corded tool with six speeds from 8,000 to 35,000 rpm, a slim body with a rubber grip and ventilation for longer sessions, and 61 accessories covering cutting, grinding, sanding, polishing, engraving, drilling and sharpening, for less than many bare Dremel tools cost. Several hundred owners rate it highly, mostly first-time buyers doing craft, model and small repair work, and the collet is the standard 1/8 inch, so every Dremel wheel and third-party disc in this guide fits it. Treat the bundled accessories as a sampler: the cut-off discs are the thin unreinforced kind and the polishing and sanding bits are consumables, so once you know which jobs you do most, buy a proper pack of those. It is corded, which is a limitation on a ladder and a benefit for an hour of grinding. For a starter, it is a lot of tool for the money.
