Dico 7200013 Cup Brush 2.5 in 120 Grit Nylon Aluminum Oxide

Product Description

The DICO 7200013 is a nylon-fill cup brush designed for surface preparation, light deburring, and cleaning applications on metal, wood, and composite materials. The brush features an aluminum oxide abrasive fill at 120 grit, providing a medium cutting action suitable for finishing and paint removal tasks. It runs at a maximum of 4,500 RPM and mounts via a 0.25-inch shank arbor, making it compatible with standard die grinders and drill chucks. The flared, straight-fill configuration helps the bristles conform to irregular surfaces for consistent contact. At 0.2 pounds, it is lightweight and easy to handle in extended use.

This cup brush is suited for trade and maintenance applications where controlled abrasion is needed without aggressive material removal. Typical uses include cleaning weld zones, preparing pipe fittings before soldering or brazing, removing mill scale, and light rust removal on metal surfaces. The 120-grit aluminum oxide nylon fill is appropriate for work where preserving the base material surface is a priority. It is commonly used by HVAC technicians, plumbers, and general maintenance professionals on both residential and light commercial job sites.

Installation Notes

Installation is performed by trade professionals or knowledgeable users with a die grinder or handheld drill. Secure the 0.25-inch shank firmly in the chuck or collet before operation and verify the tool speed does not exceed the 4,500 RPM maximum rating of the brush. Always wear appropriate eye protection and gloves when operating rotary abrasive accessories. Inspect bristles for wear or damage before each use and replace if fill material is significantly depleted.
