Weiler 90316 Cup Brush 1-3/4 in Crimped Steel 13000 Rpm

Product Description

The WEILER 90316 is a crimped-wire cup brush designed for surface preparation, weld cleaning, and deburring tasks common in fabrication, HVAC, plumbing, and general mechanical work. The brush measures 1-3/4 inches in diameter with a wire diameter of 0.0118 inches and a trim length of 3/4 inches. Steel fill wire provides durability on metal surfaces. Rated at a maximum of 13,000 RPM, this cup brush is sized for use with angle grinders and die grinders equipped with a standard 1/4-inch shank arbor. Overall length is 2-5/16 inches. The unit weighs 0.2 pounds.

This cup brush suits residential and commercial trade applications wherever aggressive wire brushing is required. Typical uses include cleaning pipe ends before fitting, removing mill scale, preparing weld zones, and stripping rust or oxidation from metal components. The crimped-wire construction provides consistent, moderate aggression across the work surface without gouging soft base metals. It is commonly used by HVAC technicians, plumbers, electricians, and sheet metal workers in both shop and field settings.

Installation Notes

Installation should be performed by a qualified tradesperson following the grinder or tool manufacturer guidelines. Always confirm the tool's rated maximum RPM is equal to or greater than 13,000 RPM before mounting this brush. Power down and disconnect the tool from its power source before mounting or removing the brush. Wear appropriate PPE including eye protection and gloves during use, as wire bristles can become projectiles at operating speed.
