Walter Surface Technologies 08X450 Type 27 Grinding Wheel

Product Description

The WALTER SURFACE TECHNOLOGIES 08X450 is a Type 27 depressed center grinding wheel designed for aggressive material removal on hard metals, stainless steel, and carbon steel. Built with a ceramic abrasive grain and resinoid bond, this wheel delivers consistent cut rates and long service life under heavy-duty grinding conditions. At 4.5 inches in diameter with a 0.25-inch thickness and a 7/8-inch arbor hole, it mounts directly to standard angle grinders. The 24-grit specification makes it suited for rapid stock removal rather than finishing work. Rated to 13,300 RPM, it meets the speed requirements of most 4.5-inch angle grinders used in fabrication, welding prep, and metal maintenance applications.

This wheel is intended for use with angle grinders in professional metalworking, fabrication shops, welding operations, and maintenance environments. Its ceramic grain excels on hard metals and stainless steel where aluminum oxide wheels lose efficiency quickly. Typical applications include weld bead removal, surface conditioning, deburring, and edge grinding on structural steel and stainless components. The Type 27 depressed center profile provides clearance for flat and contoured surface work, making it a common choice for pipeline, ironwork, and sheet metal trades.

• 13,300 RPM maximum speed rating compatible with standard 4.5-inch angle grinders
• 7/8-inch arbor hole fits standard angle grinder spindles without adapters

Compatibility

Designed for use with angle grinders accepting a 4.5-inch Type 27 wheel with a 7/8-inch arbor. Suitable for material applications including hard metals, stainless steel, and carbon steel.

Installation Notes

Installation and wheel changes should be performed by a qualified operator following ANSI B7.1 and tool manufacturer safety guidelines. Always power down and disconnect the angle grinder before mounting or removing the wheel. Confirm the grinder spindle speed does not exceed the 13,300 RPM maximum rating stamped on the wheel. Inspect the wheel for cracks or damage before each use and never use a damaged or dropped wheel.
