3M 7010300289 Flap Disc 60 Grit Ceramic Type 29 7 in

Product Description

The 3M 7010300289 is a Type 29 ceramic flap disc engineered for aggressive material removal on metal fabrication and weld blending applications. Measuring 7 inches in diameter with a 5/8-11 arbor hole, it mounts directly to standard angle grinders. The 60-grit ceramic abrasive delivers medium-grade cutting action with a cloth backing for flexibility and durability under load. Rated to 13,300 RPM, this disc is built for the sustained grinding speeds common in professional shop and field work. The conical Type 29 geometry angles the abrasive face to improve contact on flat and contoured surfaces, reducing operator fatigue during extended use.

This flap disc is suited for professional use on steel, stainless steel, and other ferrous metals in industrial, fabrication, and maintenance environments. It is a strong fit for weld seam blending, surface conditioning, and edge deburring tasks where a medium cut rate and a consistent finish are required. Licensed welders, pipefitters, ironworkers, and general metalworkers are the primary installers and users of this product.

Installation Notes

Always power down and disconnect the grinder from its power source before mounting or removing a flap disc. Confirm the tool free speed does not exceed the 13,300 RPM disc rating before operation. Wear appropriate PPE including face shield, gloves, and hearing protection during use. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or abrasive separation.
