Tru-maxx 66254443414 Flap Disc 60 Grit 7 in Type 27

Product Description

The TRU-MAXX 66254443414 is a 7-inch Type 27 flap disc designed for aggressive stock removal and blending on metal surfaces. Built with zirconia alumina abrasive on a poly-cotton backing, this coated disc delivers consistent cut rate and long service life under sustained grinding pressure. At 60 grit, it sits in the medium grade range, making it well-suited for weld blending, surface prep, and light deburring. The 7/8-inch arbor hole fits standard angle grinder spindles, and the disc is rated to 8,600 RPM for safe operation on compatible tools. It weighs approximately 0.49 pounds.

This flap disc is used in fabrication shops, maintenance facilities, and field metalwork where a reliable medium-grit disc is needed for steel and stainless steel applications. The Type 27 flat profile is preferred when working on flat surfaces or inside weld joints where a lower grinding angle improves access and control. It is a common choice for sheet metal work, structural steel prep, and stainless finishing tasks requiring a balance between material removal and surface quality.
