Norton 66254461180 Flap Disc 36 Grit Type 29 7 Inch

Product Description

The NORTON 66254461180 is a Type 29 zirconia alumina flap disc designed for aggressive material removal on ferrous and non-ferrous metals. Built with a cloth backing and a conical grinding face, it delivers consistent stock removal and a controlled finish during heavy grinding operations. Rated at a maximum of 8,600 RPM, this disc is engineered for use with 7-inch angle grinders. The 36-grit, very coarse abrasive is suited for weld blending, edge breaking, and surface preparation tasks where rapid cutting action is the priority. Trade professionals including fabricators, ironworkers, and pipefitters rely on this disc for demanding production environments.

This flap disc is appropriate for use on structural steel, stainless steel, cast iron, and weld seams in both residential fabrication shops and commercial or industrial job sites. The Type 29 conical shape directs grinding force at an angle, making it well suited for work on flat surfaces and contoured workpieces. The 7/8-inch arbor hole fits standard angle grinder spindles. The cloth-backed construction resists heat buildup and extends disc life under continuous use.
