Merit Abrasives 08834137545 Mounted Flap Wheel 320 Grit

Product Description

The MERIT ABRASIVES 08834137545 is a mounted flap wheel designed for precision surface finishing on tight contours, slots, and hard-to-reach areas. The wheel measures 5/8 inches in diameter with a 3/4 inch face width and mounts via a 1/8 inch shank for use in rotary tools and die grinders. It features a 320 grit aluminum oxide coated abrasive on a cloth backing, placing it firmly in the extra fine grade range. Rated to a maximum of 37,000 RPM, this wheel suits finish work where controlled material removal and smooth surface prep are the priority. Machinists, tool and die workers, and metal fabricators are the primary installers.

This mounted flap wheel is suited for deburring, blending, and finishing operations in metalworking applications. The small diameter and shank-mount configuration make it practical for internal bore work, die cavities, and narrow channels where larger wheels cannot fit. The aluminum oxide abrasive is effective on ferrous metals, stainless steel, and hard alloys. The extra fine 320 grit is appropriate for final-stage surface prep, light blending of weld seams, and achieving consistent scratch patterns before polishing or coating.

Key Features

• 320 grit aluminum oxide coated abrasive for extra fine surface finishing
• 5/8 inch diameter with 3/4 inch face width for access in tight workspaces
• 1/8 inch shank mount compatible with standard die grinders and rotary tools

• 37,000 maximum RPM rating supports high-speed rotary tool operation
• No interleaf construction delivers consistent abrasive contact throughout wheel life

Compatibility

Designed for use with rotary tools and die grinders accepting a 1/8 inch shank. Suitable for ferrous and non-ferrous metal finishing applications requiring an extra fine abrasive grade.

Installation Notes

Installation is performed by metalworking professionals using standard die grinders or rotary tools with a 1/8 inch collet. Verify the tool spindle speed does not exceed the 37,000 RPM maximum rating before operation. Ensure the workpiece is secured and the tool is powered off when mounting or removing the wheel. Eye protection and appropriate PPE should be worn during abrasive operations per applicable shop safety standards.
