Product Description
Milwaukee 4-1/2 in. x .045 in. x 7/8 in. Performance+ Metal Cut Off Wheel - Type 1 (25-Pack)
Model Number: 49-94-0103
The Milwaukee 49-94-0103 is a 25-pack of 4-1/2 in. x .045 in. x 7/8 in. Performance+ Metal Cut Off Wheels in the Type 1 flat profile, Milwaukee's premium-tier cut-off wheel built for longer life and faster cuts in metal and stainless steel. This is the most common cut-off wheel size on the jobsite, mounting on the standard 4-1/2 in. angle grinders nearly every shop runs, and the Performance+ formula is what separates it from a standard wheel. It uses an advanced aluminum oxide grain that holds a sharp cutting edge throughout the life of the wheel, an enhanced bonding structure that consistently releases fresh grain as the wheel wears, and a higher grain concentration, all built on two full sheets of high-strength fiberglass reinforcement. That self-sharpening action keeps the wheel cutting fast and gives the operator consistent control from the first cut to the last. The thin .045 in. kerf removes little material per pass for fast cuts, less heat in the workpiece, and less wasted stock.
Milwaukee rates the Performance+ line for up to 5X the life in metal cutting and up to 25 percent faster cutting versus standard competition. The extended life is the headline here: a single Performance+ wheel can outlast several standard wheels on the same work, which means far fewer wheel changes across a shift, more uptime, and a lower cost per cut on high-volume jobs, exactly where a 25-pack pays off. The wheels cut with wide versatility across ferrous metals, handling carbon steel, stainless steel, and nickel-based alloys, and standing up to the everyday materials those categories cover: steel stock and bar, angle iron, pipe and conduit, rebar, threaded rod, bolts, and strut. For welders, fabricators, and mechanical and structural crews cutting metal all day, the Performance+ wheel is the choice when wheel changes are slowing the work down.
These wheels fit standard 4-1/2 in. angle grinders and cut-off tools that use a 7/8 in. arbor, and Milwaukee rates them to a maximum of 13,580 RPM. Before mounting, confirm the maximum RPM printed on the wheel meets or exceeds your tool's rated speed, and never run a wheel faster than the speed marked on it. Because this is a thin cut-off wheel, use it for cutting only and never for grinding with the face of the wheel, just as a thick grinding wheel should never be used for cutting; matching the wheel to the task is a safety requirement. Inspect each wheel for cracks or damage before use, keep the tool's guard in place, and wear appropriate eye and face protection when cutting. Supplied as a 25-pack, the 49-94-0103 is bulk-sized for the high-volume crews that get the most out of the extended Performance+ life.
