Product Description
Milwaukee 4-1/2 in. x 1/4 in. x 7/8 in. Performance+ Metal Grinding Wheel - Type 27 (5-Pack)
Model Number: 49-94-0601
The Milwaukee 49-94-0601 is a 5-pack of 4-1/2 in. x 1/4 in. x 7/8 in. Performance+ Metal Grinding Wheels in the Type 27 depressed-center profile, Milwaukee's premium-tier grinding wheel built for longer life and faster material removal in metal and stainless steel. What sets the Performance+ grinding wheel apart is the abrasive: it uses premium zirconia grain rather than the aluminum oxide of the standard line. Zirconia is a tougher, self-sharpening abrasive that maintains sharp cutting edges throughout the application, driving a faster rate of material removal, and the enhanced bonding structure consistently releases fresh grain as the wheel wears to keep that removal rate up while giving more control. This is a grinding wheel, not a cut-off wheel: the thick 1/4 in. body and the depressed-center Type 27 shape are made to remove material with the face of the wheel, grinding welds flat, taking off flash and burrs, beveling and prepping edges, and stripping rust and scale. Each wheel is built with three full sheets of high-strength fiberglass reinforcement and a higher zirconia grain concentration for exceptional 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 wheel changes across a shift, along with a faster rate of removal from the premium zirconia grain. 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. The combination of tougher zirconia grain, higher grain concentration, and triple fiberglass reinforcement is what lets these wheels hold an aggressive removal rate deep into their extended life, which is exactly what welders and fabricators doing heavy daily grinding are after.
It helps to know where this wheel sits in the lineup. The Performance+ grinding wheel is the premium choice built for maximum life and fast removal with zirconia grain, while the standard metal grinding wheel uses aluminum oxide at up to 2X life for a lower cost per wheel. Choose Performance+ when heavy daily grinding makes wheel life and removal speed the priority, and the standard wheel for lighter or budget-driven work. These wheels fit standard 4-1/2 in. angle grinders that use a 7/8 in. arbor, and Milwaukee rates them to a maximum of 13,580 RPM. 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, inspect each wheel before use, keep the guard in place, and wear appropriate eye and face protection. Supplied as a 5-pack, the 49-94-0601 is a convenient quantity for the shop that wants the extended Performance+ life without committing to a larger box.
