Merit Abrasives 08834122058 Flap Wheel 120 Grit 4x2in

Product Description

The MERIT ABRASIVES 08834122058 is a 4-inch by 2-inch unmounted flap wheel designed for surface finishing, blending, and deburring on metal and other hard materials. It uses a coated aluminum oxide abrasive on a cloth backing, rated at a fine 120 grit. The wheel spins at up to 12,000 RPM and mounts via a 5/8-inch center hole onto compatible spindles or arbors. This type of flap wheel is a standard tool in metal fabrication shops, welding operations, and general industrial grinding applications. Machinists, fabricators, and maintenance technicians use it for consistent stock removal and surface prep.

This flap wheel suits operations that require controlled surface finishing on curved or flat workpieces. The 4-inch outside diameter and 2-inch face width provide a broad contact area, making it effective for blending welds, removing scale, and smoothing rough surfaces. The aluminum oxide abrasive is well suited for use on steel, stainless steel, and other ferrous materials. The cloth backing adds flexibility and durability through the cutting cycle. It ships and sells as a single unit.

Installation Notes

Installation is typically performed by machinists or fabricators. Before mounting, verify that the spindle or arbor speed does not exceed the 12,000 RPM maximum rating of the wheel. Ensure the arbor bore matches the 5/8-inch center hole before securing the wheel. Always power down and de-energize equipment before mounting or removing abrasive wheels, and inspect the wheel for cracks or damage prior to use.
