Product Description
Milwaukee 4-1/2 in. x 1/4 in. x 7/8 in. Performance+ Metal Grinding Wheel - Type 27 (10-Pack)
Model Number: 49-94-0603
The Milwaukee 49-94-0603 is a 10-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 for longer life and faster material removal in metal and stainless steel. The heart of the Performance+ grinding wheel is its premium zirconia grain, a tougher and more aggressive abrasive than the aluminum oxide used in Milwaukee's standard grinding line. Zirconia self-sharpens as it works, holding a keen cutting edge throughout the application so the wheel keeps pulling metal down fast rather than glazing and slowing, and the enhanced bonding structure releases fresh grain uniformly as the wheel wears for steady removal 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 built to remove material with the face of the wheel, flattening welds, clearing flash and burrs, beveling and prepping edges, and stripping rust and scale. Three full sheets of high-strength fiberglass reinforcement and a higher zirconia grain concentration give each wheel the durability to take heavy grinding.
Milwaukee rates the Performance+ grinding line for up to 5X the life in metal grinding versus standard competition, so each wheel outlasts several standard wheels and cuts down sharply on wheel changes over a shift, all while removing material faster thanks to the premium zirconia grain. The 10-pack is the middle quantity in the range, a practical box size for a working shop that grinds daily and wants a steady supply on the shelf without stepping up to the 25-pack. 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, holding an aggressive removal rate deep into their extended life.
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. Where the Performance+ grinding wheel is built for maximum life and fast removal with zirconia grain, 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. 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 10-pack, the 49-94-0603 keeps a full box of long-life wheels on hand for steady production grinding.
