Cgw 42842 Flap Disc Type 27 4.5 in 60 Grit 10 Per Box

Product Description

The CGW 42842 is a Type 27 flap disc designed for aggressive material removal on metal and weld surfaces. Built under the eXtreme Grind Wheel line, it features a 4.5-inch diameter with a 7/8-inch arbor bore and a 60-grit alumina abrasive cloth. Type 27 discs sit flat against the workpiece, making them suited for surface grinding rather than edge work. The overlapping abrasive flaps conform slightly to contours while delivering consistent stock removal. Sold in a box of 10, this disc is a working stock item for fabrication shops and field crews that cycle through discs at volume.

This disc fits standard 4.5-inch angle grinders used by metal fabricators, ironworkers, pipefitters, and maintenance techs. It is appropriate for grinding welds flush, removing mill scale, and preparing carbon steel surfaces for coating or inspection. The 60-grit rating places it in the medium-coarse range, delivering a balance between cut rate and surface finish. It is not intended for use on aluminum, stainless, or non-ferrous materials unless the disc is specifically rated for those substrates, which this listing does not confirm.

Compatibility

Designed for use with 4.5-inch angle grinders accepting a 7/8-inch arbor. Confirm grinder maximum RPM rating meets or exceeds the disc rating before installation.

Installation Notes

Installation and use should be performed by personnel trained in the safe operation of angle grinders. Always disconnect or de-energize the grinder before mounting or removing a disc. Inspect the disc for cracks, chips, or damage before each use and discard any disc that shows visible defects. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation. Ensure the grinder guard is in place and the tool RPM does not exceed the disc rated speed.
