3M 7010327061 Flap Disc 60 Grit Ceramic Type 27 4.5 Inches

Product Description

The 3M 7010327061 is a Type 27 ceramic flap disc designed for aggressive grinding and blending on metal surfaces. Built around a poly-cotton cloth backing rated at Y-weight, it delivers consistent stock removal at medium grit while holding up under sustained pressure. The disc spins on a threaded 5/8-11 arbor hole and is rated to a maximum of 13,300 RPM, making it compatible with standard 4.5-inch right-angle grinders. High-density flap construction keeps fresh abrasive exposed as the disc wears, extending usable life compared to conventional aluminum oxide flaps. Fabricators, welders, and metal finishing technicians use this disc for weld blending, surface conditioning, and edge work on both mild steel and stainless steel.

The 7010327061 is suited for job sites and shop environments where controlled material removal on ferrous and non-ferrous steel is required. Its Type 27 flat profile is the standard choice when working on flat surfaces or inside corners where a depressed-center profile would reduce contact area. The ceramic abrasive grain self-sharpens during use, maintaining cut rate across the life of the disc. This makes it a practical option for production welding shops, structural steel fabricators, and maintenance crews handling repeated passes on heavy weldments or mill scale removal.

Compatibility

Designed for use on steels and stainless steel with standard 4.5-inch right-angle grinders equipped with a 5/8-11 threaded arbor. Part of the 3M 967A series.

Installation Notes

Installation and disc changes must be performed by qualified personnel following grinder manufacturer guidelines and applicable ANSI B7.1 safety standards. Always power down and unplug or lock out the grinder before mounting or removing a flap disc. Verify the grinder free speed does not exceed the disc maximum RPM of 13,300 before operation. Wear appropriate PPE including face shield, gloves, and hearing protection during use.
