Walter Surface Technologies 08B450 Type 27 Grinding Wheel

Product Description

The WALTER SURFACE TECHNOLOGIES 08B450 is a Type 27 depressed center grinding wheel designed for aggressive material removal on steel and stainless steel. At 4.5 inches in diameter and 0.25 inches thick, it mounts via a 5/8-11 threaded arbor and runs at up to 13,300 RPM on a standard angle grinder. The 24-grit aluminum oxide abrasive with a resinoid bond delivers a very coarse cut rate suited for weld grinding, surface prep, and rapid stock removal. At 1 pound, it is a straightforward field consumable for fabrication and maintenance professionals.

This wheel is a direct fit for angle grinders accepting a 5/8-11 threaded mount. It is used in fabrication shops, structural steel work, pipeline work, and maintenance environments where fast, aggressive grinding on mild steel or stainless steel is required. The Type 27 depressed-center geometry keeps the wheel face low to the work surface, making it well suited for flat and contoured grinding in tight clearances.
