Value Collection PLMSC12935 Flap Disc 80 Grit Type 27 4.5 in

Product Description

The VALUE COLLECTION PLMSC12935 is a Type 27 flap disc designed for grinding and blending on metal surfaces. Built with zirconia alumina abrasive on a poly-cotton backing, it delivers consistent stock removal and a smooth finish in one pass. The disc measures 4.5 inches in diameter and mounts via a 5/8-11 threaded arbor hole, fitting standard right-angle grinders used across fabrication, welding, and maintenance applications. At 80 grit, it falls in the medium grade range, suited for moderate material removal without excessive surface damage. High-density flap construction extends disc life and maintains cutting performance through the full wear cycle.

This flap disc is intended for use on steels and stainless steel in both residential and commercial settings. Typical applications include weld blending, scale removal, edge chamfering, and surface preparation prior to coating or inspection. It is commonly used by metal fabricators, welders, pipefitters, and maintenance technicians working with angle grinders on structural steel, tube, plate, and pipe. The Type 27 depressed-center profile provides a low grinding angle well suited to flat and contoured surface work.

Key Features

• Zirconia alumina abrasive for aggressive cutting on steel and stainless steel
• 80 grit medium grade for balanced material removal and surface finish
• Type 27 depressed-center profile for flat and near-flat surface grinding
• 5/8-11 threaded arbor hole fits standard angle grinders
• High-density poly-cotton backing extends disc service life
• Rated for steels and stainless steel applications

Compatibility

Designed as a direct-fit replacement for standard 4.5-inch Type 27 flap discs with a 5/8-11 threaded arbor attachment, compatible with right-angle grinders accepting that arbor size and disc diameter.

Installation Notes

Installation and disc changes should be performed by qualified personnel following grinder manufacturer guidelines and applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and disconnect the grinder from its power source before mounting or removing a disc. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM rating marked on the disc or grinder. Wear appropriate PPE including eye protection and a face shield when operating abrasive grinding equipment.
