Walter Surface Technologies 11T042 Cut-off Wheel 60 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 11T042 is a Type 1 resinoid-bonded aluminum oxide cut-off wheel designed for fast, clean separation cuts on steel and stainless steel. At 4-1/2 inches in diameter and 3/64 inches thick, this wheel delivers a narrow kerf that reduces material waste and heat buildup at the cut line. The 60-grit aluminum oxide abrasive is reinforced for added safety under load, and the wheel is rated to a maximum of 13,300 RPM. It mounts on a 7/8-inch arbor and is sized for use with standard 4-1/2-inch angle grinders common on metal fabrication and service jobs.

This wheel is suited for cutting steel and stainless steel in both residential and commercial trade applications. Typical use cases include pipefitting, structural steel work, HVAC duct fabrication, and general metal cutting tasks where a thin-kerf wheel is preferred. The Type 1 flat profile is the standard geometry for right-angle and straight grinders, making this wheel a straightforward drop-in for most jobsite grinders with a compatible arbor size.

Installation Notes

Cut-off wheel mounting and replacement should be performed by a qualified operator following the grinder manufacturer's instructions and ANSI B7.1 safety standards. Always confirm the grinder's rated no-load RPM does not exceed the wheel's 13,300 RPM maximum before mounting. Inspect the wheel for cracks or damage before each use and never use a damaged wheel. Wear appropriate personal protective equipment including a face shield, gloves, and hearing protection during operation.
