Dremel Cut-Off Wheel Assortment 688-01

The Dremel Cut-Off Wheel Assortment 688-01 gives you 69 pieces of cutting capacity in five different wheel types, all organized in a reusable storage case with adjustable dividers. At 4.8 stars across 37 reviews, it delivers what contractors need: variety, convenience, and wheels that handle everything from frozen bolts to sheet metal.

Skip it if you only cut occasionally or prefer tool-free wheel changes. The EZ688-01 uses the EZ Lock system for tool-less wheel changes but contains only 11 pieces. This 688-01 kit shines for shops that burn through cut-off wheels regularly and need different types on hand.

The kit breaks down like this:

• 1 mandrel (part #402)
• 36 thin emery cut-off wheels 15/16” (part #409)
• 24 heavy-duty cut-off wheels 15/16” (part #420)
• 3 fiberglass-reinforced cut-off wheels 1-1/4” (part #426)
• 5 standard cut-off wheels 1-1/4” (part #540)

Cuts hardened steel, sheet metal, rusted bolts, frozen fasteners, light wood, plastic, copper, and brass. That covers most of what you’ll hit on a job site.

Storage and Professional Use

The reusable case features a clear lid, removable accessory tray, and 3 adjustable dividers. The whole thing fits into Dremel 400 Series XPR storage units if you’re running their modular system.

Common professional applications include removing rusted or frozen bolts in automotive repair, reslotting stripped screw heads for removal, cutting hardened steel for fabrication projects, and hobby/model building requiring precise cuts on small parts.

The manual tightening system takes more time than EZ Lock wheels. You loosen the screw at the top of the 402 mandrel using the Dremel wrench or small screwdriver, insert the mandrel through the wheel’s center hole, tighten the screw until firm (don’t over-tighten or you’ll crack the wheel), then insert the mandrel shank into your tool’s collet and tighten. Takes 30 seconds versus 5 seconds for EZ Lock. The trade-off? You get 69 wheels for the price of 11.

Users praise the value of having many small wheels, which are useful for tight spaces where wheels wear down quickly. The 4.8-star rating reflects that contractors find it indispensable for rusted hardware. The main complaint: standard wheels are brittle, which is common for emery discs.

Frequently Asked Questions

Do these wheels work with non-Dremel rotary tools? Yes, they work with any rotary tool accepting a 1/8 inch (3mm) shank, including Milwaukee, Bosch, and Harbor Freight brands.

What’s the difference between the wheel types included? The kit includes thin emery wheels for general cutting, heavy-duty wheels for tougher materials, and fiberglass-reinforced wheels for maximum durability. Use thin wheels for precision, heavy-duty for thicker material, and fiberglass-reinforced when you need wheels to last longer.

How long do the wheels typically last? Users note that wheels wear down quickly in tight spaces, which is why having 69 pieces matters. Standard emery wheels are more brittle than fiberglass-reinforced options.

Is the storage case durable enough for job site use? The case features a clear lid for visibility, removable tray for organization, and adjustable dividers. It’s designed to fit into Dremel’s 400 Series XPR storage system, suggesting it’s built for workshop organization rather than getting tossed around in a truck bed.
