Walter Surface Technologies 08N453 Grinding Wheel 4-1/2 in

Product Description

The WALTER SURFACE TECHNOLOGIES 08N453 is a depressed center grinding wheel rated for both Type 27 and Type 42 mounting configurations. It measures 4-1/2 inches in diameter with a 3/32-inch thickness and a 7/8-inch arbor hole. The abrasive blend of aluminum oxide and silicon carbide at 36 grit delivers aggressive stock removal on steel and stainless steel. A resinoid bond holds the grain matrix together under high rotational stress. The reinforced construction supports a maximum operating speed of 13,300 RPM. This wheel is designed for use with angle grinders and is installed by fabricators, pipefitters, and maintenance trades working on structural and process piping.

The 08N453 is specified for grinding applications on steel and stainless steel, with a listed material application designation of A36 pipe. Its dual Type 27 and Type 42 compatibility makes it usable across a wider range of angle grinder guard and flange configurations. The 36-grit aluminum oxide and silicon carbide blend suits initial weld cleanup, surface conditioning, and edge work where fast material removal is the priority over a fine finish. Typical use cases include fabrication shops, field pipefitting, and structural steel erection.

Installation Notes

Installation is performed by the operator before grinder startup. Always confirm the grinder spindle speed does not exceed the 13,300 RPM wheel rating before mounting. Inspect the wheel for cracks or chips before each use and never use a damaged wheel. Follow applicable ANSI B7.1 safety standards for abrasive wheel mounting and use proper guard coverage for the wheel type being installed.
