Value Collection PLMSC13122 Flap Disc 40 Grit Type 29 4.5 in

Product Description

The VALUE COLLECTION PLMSC13122 is a Type 29 coated flap disc designed for aggressive material removal on steel and stainless steel surfaces. The disc measures 4.5 inches in diameter with a 5/8-11 threaded arbor hole for direct mounting to standard angle grinders. Zirconia alumina abrasive at 40 grit delivers coarse-grade cutting action, making it well-suited for weld blending, surface conditioning, and rust or scale removal. The poly-cotton backing provides flexibility to conform to contoured workpieces while maintaining disc integrity under load. Fabricators, pipefitters, and metalworkers will find this disc a reliable choice for production grinding tasks.

This flap disc is intended for use on steels and stainless steel in both shop and field environments. The Type 29 angled design positions the abrasive flaps at an offset that increases surface contact and cutting efficiency compared to a flat Type 27 disc, particularly on flat stock and mild contours. The threaded arbor attachment fits the 5/8-11 spindle found on most 4.5-inch angle grinders. Typical applications include weld seam blending, edge chamfering, and heavy stock removal in metal fabrication and structural steel work.

Installation Notes

Install this disc on a grinder rated for the disc diameter and ensure the spindle thread matches the 5/8-11 arbor before mounting. Power down and disconnect the grinder from its power source before changing discs. Always inspect the disc for cracks or damage prior to use and follow ANSI B7.1 safety standards for abrasive wheel mounting and operation. Appropriate eye protection and gloves are required during use.
