Merit Abrasives 08834144457 Mounted Flap Wheel 120 Grit

Product Description

The MERIT ABRASIVES 08834144457 is a mounted flap wheel designed for precision grinding, blending, and finishing on metal and similar surfaces. It features an aluminum oxide abrasive in a non-woven coated construction with an interleaved flap design, which provides consistent stock removal and surface finishing in a single pass. Rated to 12,000 RPM maximum, this wheel mounts via a 1/4-inch shank for use in die grinders and rotary tools. At a fine 120 grit, it is suited for light deburring, surface prep, and finishing work where a smooth result is required. The cloth backing with an X-weight designation provides durability under load.

This mounted flap wheel is used in metalworking, fabrication, and maintenance applications where access to tight areas, bores, contours, or irregular surfaces is needed. The 2-inch diameter and 1-inch face width make it practical for internal diameter work, weld blending in confined spaces, and general surface conditioning on ferrous and non-ferrous metals. It is commonly installed in pneumatic or electric die grinders by machinists, fabricators, maintenance technicians, and tool-and-die professionals working in light industrial and shop environments.

Key Features

• Aluminum oxide non-woven coated abrasive for consistent fine finishing
• Interleaved flap construction maintains surface contact and extends wheel life

Installation Notes

Installation is performed by machinists or fabricators using a standard die grinder with a 1/4-inch collet or chuck. Ensure the grinder is rated at or below the 12,000 RPM maximum before mounting the wheel. Power down and disconnect the tool from its air supply or electrical source before changing abrasive accessories. Do not exceed the marked maximum RPM and inspect the wheel for damage before each use per ANSI B7 abrasive safety guidelines.
