3M 7000045106 Quick-change Disc 240 Grit 3 in Roloc Tr

Product Description

The 3M 7000045106 is a quick-change abrasive disc in the 361F series, designed for use with Roloc TR Type R attachment systems. It measures 3 inches in diameter and cuts with 240-grit aluminum oxide abrasive, placing it in the very fine grade range. The polyester cloth backing with XF backing weight gives the disc durability under load, making it suitable for light material removal, blending, and surface finishing on metal and similar substrates. Rated to 20,000 RPM, it is built for use with compatible right-angle grinders and die grinders used by metal fabricators, maintenance technicians, and industrial service pros.

This disc is suited for finishing passes on ferrous and non-ferrous metals where a refined surface is needed without heavy stock removal. The 240-grit aluminum oxide construction handles deburring, edge blending, and pre-paint surface preparation in fabrication shops, maintenance facilities, and field service environments. The Roloc TR Type R twist-lock attachment allows for fast disc changes without tools, reducing downtime during extended operations. The brown disc color identifies the 361F series product line.
