Arc Abrasives 10826AF Flap Disc 4.5x7/8 Type 29 80 Grit

Product Description

The ARC ABRASIVES 10826AF is a Type 29 flap disc designed for general-purpose grinding and blending on metal and composite surfaces. Measuring 4.5 inches in diameter with a 7/8 inch arbor hole, it runs on standard angle grinders used daily in fabrication, welding, and metalworking shops. The 80 grit aluminum oxide abrasive removes material efficiently while leaving a controlled finish. Cotton backing reinforces the flap construction, adding tensile strength and durability through the full life of the disc. Licensed tradespeople and experienced fabricators working on mild steel, aluminum, and composite materials will find this disc a dependable shop staple.

This flap disc is suited for light to medium stock removal, weld blending, and surface conditioning on mild steel, aluminum, and composite substrates. The Type 29 conical geometry positions the abrasive at an angle to the workpiece, making it effective on flat surfaces and contoured profiles alike. It is commonly used in structural steel fabrication, sheet metal work, and maintenance welding environments where a single disc needs to handle both grinding and finishing passes.
