Norton 66252843607 Type 27 Grinding Wheel 4.5x0.25x0.875

Product Description

The NORTON 66252843607 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with an aluminum oxide abrasive grain, this wheel delivers consistent cutting action on ferrous metals including mild steel, stainless, and structural materials. The 4.5-inch diameter, 0.25-inch thick wheel mounts on a 0.875-inch arbor bore and is sized for standard 4.5-inch angle grinders commonly used in fabrication, welding prep, and maintenance work. Licensed tradespeople and experienced fabricators rely on this wheel for weld blending, surface conditioning, and stock removal in both shop and field environments.

This wheel is suited for use in metal fabrication shops, construction sites, manufacturing facilities, and maintenance operations. It fits standard 4.5-inch right-angle grinders and is appropriate for tasks including weld seam grinding, deburring, and surface preparation on structural steel, pipe, and plate. The Type 27 depressed-center profile provides clearance for flush and surface grinding passes where a flat wheel profile would make contact difficult. Sold in a case quantity of 25, this SKU is well suited for shops and contractors who go through consumable abrasives at volume.

Installation Notes

Mounting and use of depressed center grinding wheels should follow ANSI B7.1 safety standards and the grinder manufacturer's published guidelines. Always inspect the wheel for cracks or damage before mounting, and confirm the grinder's RPM rating meets or exceeds the wheel's maximum operating speed. Power down and disconnect the grinder from its power source before changing wheels. Always use the appropriate guard and personal protective equipment including face shield and gloves when operating angle grinders with grinding wheels.
