Product Description
Milwaukee 4-1/2 in. x 1/4 in. x 7/8 in. Type 27 Masonry Grinding Wheel
Model Number: 49-94-4570
The Milwaukee 49-94-4570 is a 4-1/2 in. x 1/4 in. x 7/8 in. Type 27 Masonry Grinding Wheel — a heavy-duty depressed-center silicon carbide grinding wheel for grinding, shaping, and surface preparation on concrete, masonry, brick, block, and stone with 4-1/2 in. angle grinders. Silicon carbide is the correct abrasive specification for masonry grinding applications — it provides the cutting action and self-sharpening wear characteristics needed for productive grinding on the hard, abrasive mineral surfaces of concrete and masonry where aluminum oxide abrasive wheels used for steel grinding would load and glaze rapidly rather than cutting effectively. The 1/4 in. thick specification provides a larger abrasive mass than the standard 1/8 in. grinding wheel for longer wheel life in heavy masonry grinding applications — grinding weld splatter off concrete surfaces, removing form lines and high spots, shaping masonry for tight fitting, and the sustained surface grinding work of concrete renovation and preparation where wheel life directly affects the economics of the grinding operation.
The Type 27 depressed-center profile positions the grinding face below the mounting hub for flat-surface grinding at the productive low approach angle on concrete floors, block walls, and masonry surfaces. The 7/8 in. arbor bore fits standard 4-1/2 in. angle grinder spindles. Always inspect wheels for cracks before mounting, operate within the wheel's maximum rated RPM with the grinder's guard installed, and use appropriate dust protection and face shield during all masonry grinding operations — concrete grinding generates respirable crystalline silica dust that requires respiratory protection and vacuum extraction where available for OSHA compliance.
