Tru-maxx SZMFW1580 Mounted Flap Wheel 80 Grit 3in

Product Description

The TRU-MAXX SZMFW1580 is a shank-mounted flap wheel designed for deburring, blending, and finishing work on metal and similar materials. It features a coated aluminum oxide abrasive at 80 grit, placing it in the medium grade range — suited for moderate stock removal and surface conditioning. The wheel mounts via a 1/4-inch shank diameter, making it compatible with die grinders and rotary tools commonly used in fabrication, maintenance, and machine shop environments. It is rated to a maximum of 20,000 RPM and weighs approximately 0.161 pounds, keeping it lightweight for extended hand-tool use.

This mounted flap wheel is used in metalworking and general fabrication applications where controlled abrasion is needed on internal bores, contoured surfaces, or hard-to-reach areas. The 3-inch diameter and 3/4-inch face width provide a moderate contact area suitable for weld blending, surface prep before coating, and edge finishing on ferrous and non-ferrous parts. It is a standard tool for machinists, welders, maintenance technicians, and metal fabricators working with die grinders or drill press setups.

Key Features

• 80 grit aluminum oxide abrasive — medium grade for balanced stock removal and surface finish
• Coated abrasive construction provides consistent cutting action across the flap wheel face
• 1/4-inch shank diameter fits standard die grinders and rotary tool chucks
• 20,000 maximum RPM rating suitable for high-speed rotary tool use
• 3-inch diameter with 3/4-inch face width for moderate contact area on contoured surfaces
• Non-interleaved flap design for direct abrasive contact

Compatibility

Designed as a direct-fit mounted flap wheel for die grinders and rotary tools accepting a 1/4-inch shank. Suitable for use on metal, ferrous alloys, and non-ferrous materials requiring medium-grit surface conditioning or blending.

Installation Notes

Installation should be performed by a qualified machinist, fabricator, or maintenance technician familiar with rotary abrasive tooling. Verify that the spindle speed of the die grinder or rotary tool does not exceed the 20,000 RPM maximum rating of this wheel before use. Secure the shank fully into the collet and inspect the flap wheel for damage before each use. Always wear appropriate eye and face protection and ensure the work area is clear of flammable materials when grinding.
