Merit Abrasives 08834137322 Mounted Flap Wheel 120 Grit

Product Description

The MERIT ABRASIVES 08834137322 is a mounted flap wheel designed for precision surface finishing, deburring, and blending on metal and other hard materials. It features a 120-grit aluminum oxide abrasive on a cloth backing, placing it in the fine grade category for controlled material removal and smooth surface preparation. The wheel mounts on a 1/4-inch shank, making it compatible with standard die grinders and rotary tools. It is rated to a maximum of 30,000 RPM, allowing use with high-speed pneumatic or electric rotary equipment. Machinists, fabricators, and maintenance technicians are the primary installers of this type of tooling.

This mounted flap wheel suits applications that require consistent finish work in hard-to-reach areas such as bores, cavities, and contoured surfaces. The 1-3/8-inch outside diameter and 5/8-inch face width make it well suited for interior surface work, weld blending, and cleaning operations in tight geometries. It is commonly used in metal fabrication shops, maintenance facilities, and production environments where repeatable finish quality is needed on ferrous and non-ferrous workpieces.

Key Features

• 120-grit aluminum oxide coated abrasive for fine-grade surface finishing and blending
• Cloth backing provides flexibility and durability across contoured surfaces
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• 30,000 maximum RPM rating compatible with high-speed pneumatic and electric rotary tools
• Compact 1-3/8-inch diameter and 5/8-inch face width for access to bores and confined areas
• No interleaf construction for consistent flap contact with the workpiece

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/4-inch collet or chuck; verify that the tool's rated speed meets or exceeds the workpiece application requirements and does not exceed the 30,000 RPM maximum of this wheel.

Installation Notes

This mounted flap wheel is installed and operated by machinists, metal fabricators, and maintenance technicians using die grinders or rotary tools. Before mounting, ensure the tool is disconnected from its power or air supply. Secure the 1/4-inch shank firmly in the collet and confirm it is fully tightened before operation. Always verify that the tool's operating speed does not exceed the 30,000 RPM maximum rating of the wheel, and use appropriate eye and face protection per applicable ANSI safety standards.
