Merit Abrasives 08834137505 Mounted Flap Wheel 320 Grit

Product Description

The MERIT ABRASIVES 08834137505 is a mounted flap wheel designed for precision surface finishing and deburring on metal and similar materials. The wheel measures 1-3/16 inches in diameter with a 3/16 inch face width and mounts via a 1/8 inch shank for use in die grinders, rotary tools, and drill presses. It carries a 320 grit aluminum oxide coated abrasive on a cloth backing, placing it in the extra fine grade category. Rated to a maximum of 30,000 RPM, it suits controlled finishing passes where surface quality matters more than aggressive stock removal. Machinists, tool-and-die techs, and metalworkers are the primary users.

This mounted flap wheel is well suited for internal bore finishing, contour blending, and light deburring in tight workspaces where larger wheels cannot reach. The small diameter and narrow face width make it effective on inside diameters, slots, and curved profiles. It is commonly used in fabrication shops, maintenance environments, and production finishing operations where a consistent extra fine surface finish is required on ferrous and non-ferrous metals.

Key Features

• 320 grit aluminum oxide abrasive delivers an extra fine finish for final-stage surface prep
• Cloth backing provides flexibility to conform to curved and contoured surfaces
• 1/8 inch shank mounts directly in standard die grinders and rotary tools
• 30,000 maximum RPM rating suits high-speed rotary tool operation
• Compact 1-3/16 inch diameter and 3/16 inch face width allow access to confined areas
• No interleaf construction for consistent abrasive contact throughout wheel life

Compatibility

Designed for use with rotary tools, die grinders, and drill presses accepting a 1/8 inch shank mounted abrasive wheel.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard collet or chuck systems that accept a 1/8 inch shank. Confirm the tool spindle speed does not exceed the 30,000 RPM maximum rating before operation. Secure the shank fully into the collet and inspect the wheel for cracks or damage before each use. Always use appropriate eye protection and follow applicable workplace safety standards when operating mounted abrasive wheels.
