Value Collection PLMSC13125 Flap Disc 80 Grit Type 29 4.5 in

Product Description

The VALUE COLLECTION PLMSC13125 is a Type 29 flap disc designed for grinding and blending on steel and stainless steel surfaces. It features an 80-grit zirconia alumina abrasive bonded to poly-cotton backing flaps arranged at the conical Type 29 angle, which increases surface contact and improves material removal rates on flat and contoured workpieces. The threaded arbor hole accepts a standard 5/8-11 angle grinder spindle. At 4.5 inches in diameter and medium grade, this disc is suited for deburring, weld blending, and surface prep in fabrication and maintenance applications. Installation requires no tools beyond the grinder wrench.

This flap disc is used in metal fabrication shops, structural steel work, and maintenance settings where weld seams, surface scale, or mill finish need to be removed or smoothed. The Type 29 angled flap configuration works well for aggressive stock removal on flat stock as well as moderate contour work. Applicable materials include mild steels and stainless steel grades. It is typically installed and operated by welders, fabricators, and maintenance technicians working with 4.5-inch right-angle grinders.
