Bullard 30423 Type 29 Grinding Wheel 4.5in 36 Grit

Product Description

The BULLARD 30423 is a Type 29 depressed center grinding wheel designed for aggressive material removal on carbon steel and stainless steel. It measures 4.5 inches in diameter and 0.125 inches thick, with a 7/8 inch arbor hole for direct mounting to standard angle grinders. The ceramic abrasive grain is bonded with a resinoid bond and cut to a coarse 36 grit, suited for fast stock removal and weld cleanup. Maximum rated speed is 13,300 RPM. The wheel weighs approximately 0.1 pounds. Installers and fabricators working in metal trades will find this wheel a direct fit for 4.5 inch angle grinder applications.

This wheel is intended for use with 4.5 inch angle grinders in both shop and field applications. The Type 29 conical profile allows the operator to work at a low angle to the workpiece, making it effective for surface grinding, deburring, and blending on flat or slightly contoured metal surfaces. It is appropriate for use on carbon steel and stainless steel workpieces in fabrication, maintenance, and repair settings.
