Dico 7200043 Wheel Brush 4 in 240 Grit Abrasive Nylon

Product Description

The DICO 7200043 is a 4-inch diameter wheel brush designed for surface finishing, deburring, and light material removal. It uses crimped abrasive nylon fill impregnated with aluminum oxide at a 240 grit rating, placing it in the fine grade category. The 1/4-inch shank mounts directly into a drill, die grinder, or rotary tool without an adapter. With a maximum rated speed of 25,000 RPM, it suits both benchtop and handheld power tools. This brush is a standard choice for machinists, maintenance technicians, and fabricators who need consistent, controlled surface conditioning on metal or composite workpieces.

This wheel brush is suited for use in light industrial, maintenance, and fabrication environments. The 240 grit aluminum oxide abrasive nylon construction makes it appropriate for finishing passes on aluminum, steel, and plastic surfaces where aggressive material removal is not required. The 3/8-inch face width allows access to narrow slots, edges, and contoured surfaces. It is commonly used in production shops, field maintenance, and toolroom applications by machinists, millwrights, and general maintenance technicians.

Compatibility

Designed for use with 1/4-inch collet die grinders, rotary tools, and drill chucks rated at or above 25,000 RPM. Suitable for finishing operations on metal, plastic, and composite surfaces.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard 1/4-inch collet or drill chuck tooling. Verify that the tool spindle speed does not exceed the 25,000 RPM maximum rating marked on the brush before mounting. Always power down and disconnect the tool from its power source before installing or removing the brush. Eye protection and appropriate PPE should be worn during operation per ANSI B11 and shop safety standards.
