3M 7000045617 Abrasive Disc 6 Inch 40 Grit

Product Description

The 3M 7000045617 is a coated abrasive disc designed for material removal on metal, plastic, and fiberglass substrates. Built on D and E weight paper backing with an open coat construction, this disc delivers an aggressive cut while minimizing dust loading and clogging during use. The ceramic and aluminum oxide blend provides strong cut rate and extended disc life compared to conventional abrasives. At 6 inches in diameter and 40 grit, it is suited for heavy stock removal tasks such as shaping body filler and stripping paint down to bare metal. Licensed tradespeople in auto body, metal fabrication, and surface prep install and use these discs in production and shop environments.

This disc is intended for use on sanders and grinders equipped with a hook and loop backing plate. The 40 grit rating makes it appropriate for coarse material removal on metal panels, fiberglass panels, and plastic substrates. Open coat construction is particularly effective when working with fresh or soft filler, where conventional closed coat abrasives tend to load quickly and lose cutting efficiency. Sold in a box quantity with a minimum order of 5 units, making it practical for shop stocking.
