Product Description
Milwaukee 4-1/2 in. x 1/4 in. x 5/8-11 Performance+ Metal Grinding Wheel - Type 27 (5-Pack)
Model Number: 49-94-0607
The Milwaukee 49-94-0607 is a 5-pack of 4-1/2 in. x 1/4 in. x 5/8-11 Performance+ Metal Grinding Wheels in the Type 27 depressed-center profile, Milwaukee's premium-tier grinding wheel built with an integrated 5/8-11 threaded hub. That threaded hub is the defining feature of this version: instead of a plain arbor hole that requires a backing flange and lock nut, the wheel threads directly onto a standard 4-1/2 in. angle grinder spindle, mounting fast and securely with no flange, nut, or adapter to fumble with. Like the rest of the Performance+ grinding line, it uses premium zirconia grain rather than aluminum oxide, a tougher, self-sharpening abrasive that maintains sharp cutting edges throughout the application for a faster rate of material removal, and an enhanced bonding structure that continuously exposes fresh grain as the wheel wears for sustained efficiency and more control. This is a grinding wheel, not a cut-off wheel: the 1/4 in. thick body and depressed-center Type 27 shape are made to remove material with the face of the wheel. It is built with three full sheets of high-strength fiberglass reinforcement and a higher zirconia grain concentration for durability under heavy grinding.
Milwaukee rates the Performance+ grinding line for up to 5X the life in metal grinding versus standard competition, so a single wheel outlasts several standard wheels and means far fewer changes, with a faster removal rate from the premium zirconia grain. The Type 27 depressed-center profile positions the abrasive face below the mounting hub, which lets you grind flat surfaces at a low approach angle for the most productive and least fatiguing sustained grinding. The wheels grind carbon steel, stainless steel, and nickel-based alloys, and stand up to the full range of ferrous work: steel plate and bar, angle iron, pipe and structural sections, rebar, and weldments, making them a strong choice for fabrication, welding, construction, and industrial metalworking.
These wheels fit standard 4-1/2 in. angle grinders that use a 5/8-11 threaded spindle, and Milwaukee rates them to a maximum of 13,580 RPM. Choose this threaded-hub version if your grinder or workflow uses direct-thread mounting; if you run a flange-and-nut setup, the 7/8 in. arbor-hole version of this same Performance+ wheel is available instead. Because this is a grinding wheel, work with the face for material removal and never use it as a cut-off wheel for edge cutting, just as a thin cut-off wheel should never be used for grinding; matching the wheel to the task is a safety requirement. Always confirm the maximum RPM printed on the wheel meets or exceeds your grinder's rated speed and never exceed it, inspect each wheel before use, keep the guard in place, and wear appropriate eye and face protection when grinding. Supplied as a 5-pack, the 49-94-0607 is a convenient quantity for the shop that wants the extended Performance+ life in a direct-thread wheel.
