Walter Surface Technologies 15L456 Type 29 Grinding Wheel

Product Description

The WALTER SURFACE TECHNOLOGIES 15L456 is a Type 29 depressed center grinding wheel designed for heavy-duty material removal with an angle grinder. Built from aluminum oxide abrasive at 60 grit (medium grade), it delivers consistent stock removal on steel, stainless steel, aluminum, and other non-ferrous metals. The wheel measures 4.5 inches in diameter with a 5/8 inch hole and a 5/8-11 threaded connector. A maximum operating speed of 13,300 RPM makes it suitable for high-speed angle grinder applications. Licensed tradespeople and fabricators working in metal fabrication, structural steel, and maintenance rely on this type of wheel for weld blending, surface conditioning, and edge work.

The 15L456 is intended for use with angle grinders in both shop and field environments. Its Type 29 conical profile allows for aggressive grinding at a low angle of attack, which is well suited to flat stock, weld seams, and contoured surfaces. Material application range covers steel, stainless steel, aluminum, and non-ferrous metals, making it a versatile choice across industrial, construction, and fabrication settings where a single abrasive wheel needs to handle varied workpiece materials.

Installation Notes

Mounting and wheel changes must be performed by qualified personnel with the grinder fully powered down and unplugged. Verify that the angle grinder spindle speed rating meets or exceeds the wheel maximum RPM before mounting. Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately. Follow ANSI B7.1 safety requirements and always use the appropriate guard during operation.
