Product Description
Milwaukee 4-1/2 in. x 1/4 in. x 7/8 in. Type 27 Grinding Wheel
Model Number: 49-94-4520
The Milwaukee 49-94-4520 is a 4-1/2 in. x 1/4 in. x 7/8 in. Type 27 Grinding Wheel for use with 4-1/2 in. angle grinders — a heavy-duty depressed-center grinding wheel for aggressive material removal on steel and ferrous metal. At 1/4 in. thick, this is the heavy-duty specification for the most demanding 4-1/2 in. grinder applications where maximum abrasive mass provides the longest wheel life in sustained weld bead removal, large bevel grinding, and aggressive stock removal from thick structural steel. Aluminum oxide abrasive provides the cutting aggressiveness and controlled wear rate appropriate for ferrous metal grinding where consistent material removal rate and wheel longevity are both important for production grinding economics. The Type 27 depressed-center profile positions the grinding face below the mounting hub for productive flat-surface grinding at the low approach angle on structural steel plates, fabricated assemblies, and weldments.
The 7/8 in. arbor bore fits standard 4-1/2 in. angle grinder spindles for direct mounting with the standard arbor washer. For lighter general surface grinding where economy at moderate consumption rate is the priority, Milwaukee's 1/8 in. standard-thickness grinding wheel is available — the 1/4 in. specification is specifically the right choice for the heaviest, most aggressive 4-1/2 in. grinder applications. Always inspect wheels for cracks before mounting, operate within rated RPM with the guard installed, and use appropriate face shield and PPE during all grinding operations.
See Milwaukee's complete 4-1/2 in. grinding wheel lineup for both 1/4 in. heavy-duty and 1/8 in. standard-thickness specifications across all application types.
