Walter Surface Technologies 15L503 Type 29 Grinding Wheel

Product Description

The WALTER SURFACE TECHNOLOGIES 15L503 is a Type 29 depressed center grinding wheel designed for use with angle grinders in demanding metal fabrication and surface preparation work. It measures 5 inches in diameter with a 5/8-11 threaded hub and is constructed from aluminum oxide abrasive at a 36 grit coarse grade. Rated to a maximum of 12,200 RPM, this wheel handles aggressive material removal on steel, stainless steel, aluminum, and other non-ferrous metals. It weighs 0.042 pounds. Licensed tradespeople and skilled fabricators working in shop or field environments are the primary users of this wheel.

This wheel suits residential and commercial metal fabrication, weld blending, deburring, and surface conditioning applications. The Type 29 conical profile allows for an optimized contact angle when working on flat or curved surfaces, making it a practical choice for pipe work, structural steel, and sheet metal operations. Compatible with standard angle grinders accepting a 5/8-11 threaded spindle connection, it performs across a range of grinding tasks where coarse material removal is required.
