Product Description
Milwaukee 4-1/2 in. x 1/4 in. x 7/8 in. Metal Grinding Wheel - Type 27 (10-Pack)
Model Number: 49-94-0503
The Milwaukee 49-94-0503 is a 10-pack of 4-1/2 in. x 1/4 in. x 7/8 in. Metal Grinding Wheels in the Type 27 depressed-center profile, built for long life and fast material removal in metal and stainless steel. The 4-1/2 in. diameter with a 7/8 in. arbor is the most common grinder wheel size on the jobsite, so these mount on the standard 4-1/2 in. angle grinders most shops already run. This is a grinding wheel rather than a cut-off wheel: the thick 1/4 in. body and the depressed-center Type 27 shape are made for taking material down with the face of the wheel, grinding welds flat, removing flash and burrs, beveling and prepping edges, cleaning up cut ends, and stripping rust, scale, and old coatings. The offset hub lets the wheel work into the surface at a proper grinding angle while keeping the grinder body clear. Each wheel pairs resin bonding agents with aluminum oxide grain for smooth, controlled removal, and carries three full sheets of high-strength fiberglass reinforcement, one more than Milwaukee's cut-off wheels, to handle the face loading that grinding puts on the wheel.
Milwaukee rates this metal line for up to 2X the life and rapid material removal versus standard competition, so the wheels grind longer between changes and take metal down faster while staying smooth and controlled under the grinder. They 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 aluminum oxide grain keeps biting into the metal as it wears instead of glazing over, maintaining the removal rate deep into the wheel's life, which is what makes the 4-1/2 in. size the workhorse choice for welders, fabricators, and structural and maintenance crews doing daily grinding.
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 of the wheel 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 run a wheel faster than the speed marked on it. Inspect each wheel for cracks or damage before use, keep the grinder guard in place, and wear appropriate eye and face protection when grinding. Supplied as a 10-pack, the 49-94-0503 keeps a full box on hand for the steady wheel consumption of production grinding.
