Merit Abrasives 08834137375 Mounted Flap Wheel 320 Grit

Product Description

The MERIT ABRASIVES 08834137375 is a mounted flap wheel designed for precision surface finishing and blending on metal, composites, and other hard materials. Built with a ceramic alumina abrasive on a cloth backing, it delivers consistent stock removal and a fine surface finish at an extra fine 320 grit rating. The 1/4-inch shank mounts directly to a die grinder or rotary tool, making it a standard reach-and-finish tool for machinists, fabricators, and maintenance technicians working in tight spaces or on contoured surfaces. Rated to 25,000 RPM, it handles high-speed applications without compromising wheel integrity.

This flap wheel is suited for deburring, blending weld seams, surface prep, and finish work on interior bores, slots, and curved profiles. The 2-inch diameter and 1-inch face width make it effective for medium-radius contours and flat surfaces where a larger wheel would not fit. It is a common tool in metal fabrication shops, aerospace maintenance, and general manufacturing environments. No interleaf construction keeps the design straightforward and cost-effective for high-volume finishing operations.

Key Features

• Ceramic alumina abrasive for consistent cut rate and long service life on hard metals
• 320 grit extra fine grade for smooth surface finishing and light stock removal
• Cloth backing provides flexibility to conform to contoured and irregular surfaces
• 1/4-inch shank mounts directly to standard die grinders and rotary tools
• 25,000 RPM maximum rating suitable for high-speed pneumatic and electric tools
• 2-inch diameter with 1-inch face width for access in confined or contoured areas

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank. Suitable for metal, composites, and similar hard materials requiring extra fine surface finishing.

Installation Notes

Always verify that the tool spindle speed does not exceed the 25,000 RPM maximum rating before mounting. Secure the 1/4-inch shank fully in the collet and confirm it is tightened before operation. Wear appropriate eye protection and gloves when operating mounted abrasive wheels. Inspect the wheel for damage before each use and replace immediately if any flaps are torn or the shank is bent.
