Weiler 93643 Cup Brush 3in Steel Crimped Wire 14000 Rpm

Product Description

The WEILER 93643 is a 3-inch diameter crimped wire cup brush designed for aggressive surface preparation and cleaning on metal, weld seams, and fabricated components. Constructed with steel fill wire at 0.014 inches in diameter, the crimped configuration provides consistent contact pressure and flexibility across irregular surfaces. With a maximum speed rating of 14000 RPM, it delivers efficient stock removal and surface finishing when mounted to a compatible angle grinder. This brush is a standard tool for welders, fabricators, metal workers, and HVAC or plumbing contractors performing surface prep before brazing or welding operations.

The WEILER 93643 is suited for use in both shop and field environments where rust removal, weld spatter cleanup, paint stripping, or general metal surface conditioning is required. Its threaded arbor design with a 5/8-11 thread makes it compatible with most standard angle grinders used in commercial and residential trades. The 1-inch trim length supports consistent wire exposure and controlled aggressiveness throughout the brush life cycle.
