Weiler 90340 Wheel Brush 3/4 in Crimped Carbon Steel

Product Description

The WEILER 90340 is a shank-mount wheel brush designed for deburring, cleaning, and surface preparation on metal workpieces. It features a 3/4-inch outside diameter wheel with crimped carbon steel wire fill, encapsulated for secure filament retention during high-speed operation. Rated to 20,000 RPM, this brush mounts via a 1/4-inch shank included with the unit, making it compatible with die grinders and drill-press setups. Filament wire diameter falls in the 0.0100 to 0.0199-inch range, providing moderate aggression suitable for light deburring and rust or scale removal. The 7/8-inch trim length delivers consistent contact pressure across the work surface.

This wheel brush is suited for use in metalworking, fabrication, and maintenance applications where a rotary tool or die grinder is the primary driver. It is commonly used by machinists, welders, maintenance technicians, and metalworking tradespeople who need a small-diameter brush for tight clearances or intricate part geometry. The shank-mount configuration makes it practical for bench-mounted drilling equipment or handheld pneumatic and electric rotary tools.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard rotary tools or drill-press equipment. Before mounting, confirm the tool spindle speed does not exceed the 20,000 RPM rating marked on this brush. Secure the shank fully in the collet or chuck before operating, and ensure the work area is clear of bystanders. Always wear appropriate eye protection when operating wire brushes at speed.
