3M KP87605 Quick-change Disc 150 Grit 3 Inches Roloc Tr

Product Description

The 3M KP87605 is a 3-inch quick-change abrasive disc designed for use with Roloc TR and Type R attachment systems. Part of the 3M 361F Series, this coated disc features aluminum oxide abrasive grain bonded to a polyester cloth backing with a YF backing weight. Rated at 20,000 RPM, it operates at 150 grit, placing it in the very fine grade range. The disc is designed for controlled surface finishing, blending, and prep work in metalworking, fabrication, and light industrial applications. Installation is tool-free — the Type R button attaches directly to compatible disc pads without fasteners.

This disc is suited for metal surface preparation, weld blending, deburring, and finish work in fabrication shops, maintenance environments, and industrial service settings. The polyester cloth backing provides flex and durability on curved or contoured surfaces. Sold in packages of 10, the KP87605 is a working-quantity pack appropriate for job-site or shop use. Licensed tradespeople and industrial technicians performing surface prep work prior to coating or welding will find this disc fits standard quick-change workflows.
