Weiler 56473 Type 27 Depressed Center Wheel 4 in 24 Grit

Product Description

The WEILER 56473 is a Type 27 depressed center grinding wheel designed for aggressive material removal on steel surfaces. It measures 4 inches in diameter and 1/4 inch thick, with a 5/8 inch arbor hole for secure mounting on a right angle grinder. The wheel is constructed with aluminum oxide abrasive bonded in a resinoid matrix and carries a coarse 24-grit rating, making it well suited for weld grinding, surface prep, and stock removal. A reinforced construction supports operation up to 15,200 RPM. Hardness code R indicates a firm bond retention suited for ferrous metal work. Weight is 0.27 pounds.

This wheel is intended for use with right angle grinders in fabrication, maintenance, and metalworking applications. It is appropriate for both field service and shop use where rapid material removal from steel is required. Typical users include pipefitters, ironworkers, millwrights, and maintenance mechanics working with structural steel, weldments, and plate stock. The Type 27 profile allows the wheel to be used at a low grinding angle, improving operator control during heavy grinding passes.

Installation Notes

Installation and wheel changes must be performed by a qualified operator with the grinder powered off and unplugged or locked out per OSHA lockout/tagout requirements. Verify that the grinder spindle speed does not exceed the 15,200 RPM maximum rating marked on the wheel before mounting. Inspect the wheel for cracks or damage before each use and never use a damaged wheel. Ensure the wheel guard is properly installed and the arbor nut is tightened securely before operation.
