Dewalt DWA8282 Flap Disc 80 Grit Ceramic Type 29 4.5 in

Product Description

The DEWALT DWA8282 is a Type 29 ceramic alumina flap disc designed for aggressive material removal on steel and stainless steel surfaces. Built with a cotton backing and rated at 8,700 RPM, this disc mounts via a 7/8-11 arbor hole and fits standard 4.5-inch angle grinders. The 80-grit medium grade makes it well suited for weld blending, surface prep, and stock removal where a consistent scratch pattern and long disc life are required. Licensed tradespeople and fabricators reach for this disc when working with ferrous and non-ferrous metals that demand a durable, cool-cutting abrasive.

The DWA8282 is appropriate for both residential and light commercial fabrication environments. Typical applications include grinding weld beads, deburring cut edges, and preparing steel or stainless steel surfaces prior to coating or inspection. The Type 29 angle geometry increases the contact area on flat and contoured workpieces, improving material removal rates over flat Type 27 discs in many grind angles. This disc is sold in a package quantity of 10 and carries a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified tradespeople familiar with angle grinder safety practices. Always disconnect or de-energize the grinder before mounting or removing a disc. Verify the grinder spindle speed does not exceed the 8,700 RPM maximum rating of this disc before operation. Inspect the disc for cracks or damage prior to each use and never operate a damaged abrasive.
