Walter Surface Technologies 11T542 Cut-off Wheel 60 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 11T542 is a Type 1 resinoid-bonded cut-off wheel engineered for fast, clean cuts on steel and stainless steel. Measuring 4-1/2 inches in diameter and 1/32 inches thick, this ultra-thin wheel minimizes material loss and heat buildup at the cut line. The 60-grit zirconia alumina abrasive delivers aggressive stock removal while the reinforced construction handles the lateral stress of angle grinder use. Rated to 13300 RPM, it is compatible with standard 7/8-inch arbor angle grinders. Fabricators, pipefitters, and ironworkers reach for this wheel when precision cutoff work on ferrous and stainless material is required.

This cut-off wheel is designed for use with angle grinders in fabrication shops, field pipework, and structural steel applications. Its 1/32-inch profile makes it well suited for thin-kerf cuts where minimizing heat-affected zones on stainless steel is a priority. The zirconia alumina grain self-sharpens under pressure, maintaining cut speed through the wheel life. Typical users include pipefitters, welders, sheet metal workers, and maintenance mechanics working on ferrous metals in both shop and field environments.

Key Features

• Zirconia alumina abrasive grain for aggressive, self-sharpening cutting action on steel and stainless steel
• Ultra-thin 1/32-inch profile minimizes kerf width and reduces heat input at the cut
• Reinforced resinoid bond handles high-stress angle grinder use
• Type 1 flat wheel geometry for straight cutoff operations
• 13300 RPM maximum speed rating suits most 4-1/2-inch angle grinders
• 7/8-inch arbor hole fits standard angle grinder spindles

Compatibility

Designed for use with 4-1/2-inch angle grinders equipped with a 7/8-inch arbor. Rated for cutting steel and stainless steel. Verify that the grinder's no-load RPM does not exceed 13300 RPM before mounting.

Installation Notes

Cut-off wheels must be mounted and operated by qualified personnel following ANSI B7.1 and the grinder manufacturer's safety guidelines. Always inspect the wheel for cracks or damage before mounting and never use a wheel whose maximum RPM rating is below the grinder's no-load speed. Ensure the guard is in place and PPE including eye and face protection is worn. Do not apply side pressure to a Type 1 cut-off wheel - these wheels are rated for peripheral cutting only.
