Product Description
Milwaukee 4-1/2 in. x .045 in. x 7/8 in. Type 1 Cut-Off Wheel
Model Number: 49-94-4500
The Milwaukee 49-94-4500 is a 4-1/2 in. x .045 in. x 7/8 in. Type 1 Cut-Off Wheel for use with 4-1/2 in. angle grinders — a thin aluminum oxide abrasive cutting wheel for fast, precise cut-off operations on steel, stainless steel, and ferrous metal in fabrication, maintenance, and construction work. The .045 in. ultra-thin wheel profile is the standard cut-off wheel specification that provides the minimum kerf width for the least material waste, fastest cutting speed through the reduced cutting resistance of a narrower abrasive section, and the lowest heat input to the workpiece per cut — all valuable characteristics for production cutting of conduit, structural steel, threaded rod, angle iron, and plate steel where the thin kerf reduces cycle time and material distortion at cut edges. The Type 1 profile is a flat wheel that cuts with the face of the wheel rather than the side, used at 90° to the workpiece surface for the standard straight cutting applications that cut-off wheels are designed for.
Aluminum oxide abrasive provides the cutting aggressiveness and wheel wear rate appropriate for ferrous metal cut-off work — it aggressively cuts through the material while the wheel wears at a controlled rate that maintains a sharp cutting face throughout the wheel's service life. The 7/8 in. arbor bore fits standard 4-1/2 in. angle grinder spindles with the standard arbor washer for secure wheel mounting. Always use the angle grinder's guard during cut-off wheel operation, inspect wheels for cracks before mounting, operate within the wheel's maximum rated RPM, and use appropriate face shield and PPE protection during all cutting operations.
