Pferd 62211623 Type 27 Grinding Wheel 4.5 in Aluminum Oxide 46 Grit

Product Description

The PFERD 62211623 is a Type 27 depressed center grinding wheel designed for aggressive material removal on steel and stainless steel. It measures 4.5 inches in diameter and 0.25 inches thick, with a 0.875-inch arbor hole for standard angle grinder mounting. The abrasive is aluminum oxide at 46 grit, bonded with a resinoid bond that handles the heat and vibration of sustained grinding. Maximum rated speed is 13,300 RPM. This wheel is installed and used by metal fabricators, pipefitters, ironworkers, and maintenance mechanics who need reliable stock removal on ferrous materials.

This wheel fits standard 4.5-inch angle grinders and is suited for grinding welds, deburring heavy stock, and blending on carbon steel and stainless steel workpieces. The Type 27 depressed-center profile keeps the grinding face at a low angle to the workpiece, improving operator control and surface access in tight or flat work areas. It is a common choice for both shop and field work where consistent cut rate and wheel life are required on ferrous metals.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and disconnect the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never exceed the marked maximum RPM. Ensure the arbor flange and nut are properly seated and torqued according to the grinder manufacturer specifications before operation.
