Weiler 98424 Wheel Brush 3/4 in Crimped Carbon Steel 37000 Rpm

Product Description

The WEILER 98424 is a small-diameter wheel brush designed for use with rotary tools, die grinders, and similar power equipment. It features a crimped carbon steel fill that provides flexible, consistent contact across irregular surfaces. The 3/4 inch outside diameter and 1/8 inch shank make it well suited for deburring, surface preparation, cleaning, and light material removal in confined areas. Rated to 37,000 RPM, this brush handles the high speeds common to pneumatic and electric die grinders. The shank is included, and the brush is not encapsulated, making it a straightforward drop-in for compatible collet chucks. Machinists, fabricators, maintenance mechanics, and tool-and-die tradespeople are the primary users.

This wheel brush is used in applications where a larger brush cannot reach — tight bores, slots, ports, weld seams, and small castings. It is suited for ferrous metal work where carbon steel wire is compatible with the base material. Typical tasks include removing burrs left by drilling or milling, cleaning corrosion from threaded fasteners, and scuffing surfaces before bonding or coating. Both shop and field maintenance environments use brushes of this type regularly.

Key Features

• Crimped wire fill for flexible, consistent surface contact on irregular geometry
• Carbon steel fill material compatible with ferrous metal deburring and cleaning
• 37,000 RPM maximum speed rating suitable for high-speed die grinders
• 1/8 inch shank diameter fits standard collet chucks on most rotary tools
• 3/16 inch trim length for precise, controlled wire engagement
• Shank included — no separate arbor required

Compatibility

Designed as an OEM-style replacement or direct-use wheel brush for rotary tools and die grinders fitted with a 1/8 inch collet or chuck.

Installation Notes

Installation is performed by inserting the 1/8 inch shank into the collet of a compatible rotary tool or die grinder and tightening per the tool manufacturer's procedure. Always confirm the tool's maximum RPM rating meets or exceeds 37,000 RPM before operation. Wear appropriate eye protection and ensure the workpiece is secured before running the brush. Do not exceed the rated maximum speed.
