Norton 66254420006 Powerflex Flap Disc 7in 40 Grit Type 29

Product Description

The NORTON 66254420006 is a Powerflex Type 29 flap disc designed for aggressive material removal and surface blending on metal workpieces. At 7 inches in diameter with a 7/8-inch arbor hole and 40-grit abrasive, this disc delivers coarse cutting action suited for weld grinding, rust removal, and stock removal on steel and other ferrous metals. The conical Type 29 profile keeps abrasive in consistent contact with the work surface, making it effective on flat and contoured surfaces alike. Grinding professionals and fabricators install this disc on standard angle grinders to handle demanding material removal tasks.

This flap disc is suited for industrial and professional use in fabrication shops, construction sites, and maintenance applications. The 40-grit rating makes it appropriate for initial stock removal and heavy surface preparation before finer finishing steps. It is sold in case quantities of 10 discs, making it practical for sustained production grinding work where disc consumption is high.
