Merit Abrasives 08834137485 Mounted Flap Wheel 320 Grit

Product Description

The MERIT ABRASIVES 08834137485 is an aluminum oxide mounted flap wheel designed for precision surface finishing on metal, wood, and composite materials. With a 5/8-inch diameter and 5/8-inch face width, this compact wheel fits into tight spaces and contoured surfaces where flat abrasives cannot reach. The cloth-backed flaps deliver consistent scratch patterns at an extra fine 320 grit rating, making it suitable for final-stage deburring, blending, and light stock removal. It mounts via a 1/8-inch shank and is rated to a maximum of 37,000 RPM. Machinists, fabricators, and tool-and-die technicians are the typical installers and operators of this tool.

This mounted flap wheel is well suited for die grinder applications in both production and maintenance environments. Its compact form factor makes it a common choice for finishing bores, ports, weld seams, and interior contours on fabricated assemblies. The extra fine grit designation targets surface refinement rather than aggressive material removal, making it appropriate as a finishing step after coarser grinding operations in metalworking and woodworking shops alike.

Installation Notes

This wheel is installed by a machinist or fabricator using a die grinder or rotary tool with a compatible 1/8-inch collet. Always confirm the tool spindle speed does not exceed the 37,000 RPM maximum rating before operation. Inspect the wheel for damage before mounting, and never exceed the rated speed. Appropriate eye protection and gloves should be worn during use per standard shop safety practices.
