Walter Surface Technologies 11T342 Grinding Wheel 4.5in 60 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 11T342 is a depressed center grinding wheel designed for aggressive material removal on angle grinders. Built to both Type 27 and Type 42 profiles, it measures 4.5 inches in diameter and 3/64 inches thick with a 5/8-11 threaded arbor hole. The abrasive material is 60-grit aluminum oxide bonded with a resinoid bond and reinforced for high-speed use. It is rated to a maximum of 13,300 RPM. Licensed trades and fabricators working with ferrous and non-ferrous metals rely on this wheel for consistent stock removal in production and field environments.

This grinding wheel is suited for use on sheet metal, stainless steel, and mild steel in both shop and on-site applications. Its dual Type 27 and Type 42 classification makes it compatible with a range of standard angle grinder guard configurations. The 60-grit aluminum oxide abrasive provides a balance of cut rate and surface finish appropriate for weld grinding, surface prep, and edge work. It is a single-piece consumable sized for 4.5-inch angle grinders commonly used in HVAC fabrication, structural steel, and general metalworking trades.
