Cgw 39931 Aluminum Oxide Flap Wheel 40 Grit 10 Per Box

Product Description

The CGW 39931 is an aluminum oxide flap wheel designed for deburring, blending, and surface conditioning on metal workpieces. The wheel measures 2 inches in diameter by 1 inch in width with a 1/4-inch shank, making it compatible with standard die grinders and drill chucks. The 40-grit aluminum oxide abrasive is well suited for aggressive stock removal and weld blending on steel, stainless steel, and other ferrous metals. A firm backing supports consistent abrasive contact across the full face of the wheel. Each box contains 10 wheels.

This flap wheel is a shop staple for metal fabricators, pipefitters, welders, and maintenance tradespeople who need a reliable mounted abrasive for tight-access grinding and blending work. The 1/4-inch shank fits the most common die grinder collets found in fabrication shops, HVAC sheet metal work, and plumbing rough-in environments. The 40-grit cut rate makes it appropriate for initial weld dressing and heavier surface prep before finer finishing steps.
