Dico 7200049 Wheel Brush 4 in 120 Grit Abrasive Nylon

Product Description

The DICO 7200049 is a 4-inch diameter wheel brush designed for surface finishing, deburring, and blending on metal, wood, and composite materials. The brush uses crimped abrasive nylon filaments impregnated with aluminum oxide at 120 grit, delivering consistent medium-grade abrasive action across the work surface. The 1/4-inch shank mounts directly in a drill press, hand drill, or rotary tool without additional hardware. With a maximum rated speed of 2500 RPM, the brush is suited for controlled, lower-speed finishing passes where wire brushes would leave too aggressive a surface profile. Installers and fabricators working on light deburring and surface prep will find this a straightforward fit for bench and field work.

This wheel brush is used in metal fabrication shops, HVAC duct and fitting preparation, plumbing pipe end cleanup, and general maintenance applications where a moderate abrasive cut is needed. The 3/8-inch face width keeps the contact zone narrow, making it practical for slot cleaning, weld bead blending, and edge work on fittings and brackets. It is suitable for use in both residential and light commercial trade settings wherever hand-held rotary tool access is practical.

Key Features

• 4-inch outside diameter with 3/8-inch face width for focused abrasive contact
• Crimped abrasive nylon fill material with aluminum oxide for consistent medium-grit cutting action

Compatibility

Designed for use with any drill press, hand drill, or rotary tool accepting a 1/4-inch shank, making it a standard fit for common trade and shop rotary equipment.

Installation Notes

Verify the tool chuck or collet is rated for the 1/4-inch shank before mounting. Do not exceed the 2500 RPM maximum rated speed — confirm the tool speed setting before operation. Wear appropriate eye protection and secure the workpiece before applying the brush. Inspect filaments for wear or damage before each use and replace the brush if fill material is significantly depleted.
