Dremel 505 Mounted Flap Wheel 120 Grit Aluminum Oxide

Product Description

The DREMEL 505 is a mounted flap wheel abrasive designed for use with rotary tools. It features a coated aluminum oxide abrasive construction at 120 grit, placing it in the fine grade range — suited for light material removal, surface blending, and finishing work on metal, wood, and similar materials. The 1/8-inch shank mounts directly into compatible rotary tool chucks or collets. With an outside diameter of 1.125 inches and a face width of 3/16 inches, this compact wheel is intended for detail work in confined areas. Installation and use are handled by machinists, fabricators, and tool-and-die technicians as well as skilled tradespeople performing surface prep or finishing.

This mounted flap wheel is suited for rotary tool applications requiring controlled abrasion in tight spaces. Typical uses include deburring, light stock removal, and surface conditioning on metal parts, welds, and wood components. The small diameter and shank-mount design allow precise control during hand-held rotary tool operation. It is sold as a single unit, making it appropriate as a direct replacement or supplemental abrasive for existing rotary tool setups.

Ensure the rotary tool is powered off and unplugged or the battery removed prior to changing accessories. Do not exceed the maximum RPM rating of the rotary tool or the abrasive wheel. Eye protection should be worn during all grinding and surface finishing operations.
