Weiler 98427 Wheel Brush 1.5 in Crimped Carbon Steel 25000 Rpm

Product Description

The WEILER 98427 is a small-diameter wheel brush designed for rotary tool and die grinder applications. It mounts via a 0.125-inch shank and spins safely up to 25,000 RPM, making it well-suited for deburring, cleaning, and surface preparation work in tight or hard-to-reach areas. The brush uses crimped carbon steel wire with a filament diameter of up to 0.0099 inches, which delivers moderate aggression and good conformability across irregular surfaces. With a 1.5-inch outside diameter and a 0.5-inch trim length, this is a compact, purpose-built brush for precision detail work in metal fabrication, maintenance, and finishing trades.

This wheel brush is used in metalworking environments where controlled wire action is needed on small workpieces, weld seams, casting flash, or corroded fasteners. It is a common tool for maintenance technicians, pipefitters, millwrights, and fabricators who need consistent surface prep performance in confined spaces. The shank-mount design means it threads directly into a die grinder or rotary tool collet without additional adapters.

Key Features

• Crimped carbon steel wire for moderate aggression and surface conformability
• Rated to 25,000 RPM for use with high-speed die grinders and rotary tools
• 1.5-inch outside diameter sized for detail and confined-space applications
• 0.125-inch shank included — no separate mandrel required
• 0.5-inch trim length provides controlled wire contact
• Filament wire diameter up to 0.0099 inches for fine to medium surface work

Compatibility

Designed as an OEM-style replacement or direct-use shank-mount wheel brush for die grinders and rotary tools accepting a 0.125-inch collet or shank.

Installation Notes

Installation is performed by inserting the 0.125-inch shank into the collet of a compatible die grinder or rotary tool and tightening per the tool manufacturer's torque guidance. Always confirm the tool's rated RPM meets or exceeds 25,000 RPM before operation. Wear appropriate PPE including eye protection and gloves, as wire bristles can shed under load. Do not exceed the brush's maximum RPM rating.
