3M KP87603 Quick-change Disc 100 Grit 3 in Roloc Tr

Product Description

The 3M KP87603 is a coated abrasive quick-change disc designed for use with Roloc TR and Type R attachment systems. Part of the 3M 361F Series, this disc measures 3 inches in diameter and features 100-grit aluminum oxide abrasive bonded to a polyester cloth backing with a YF backing weight. The brown coated surface delivers fine-grade material removal suitable for deburring, blending, and surface conditioning on metal substrates. It is rated for a maximum speed of 20,000 RPM. Sold in packages of 10, this disc is a standard consumable for grinding and finishing operations in fabrication, HVAC, and mechanical trade environments.

This disc is suited for use on metal surfaces where controlled material removal or surface prep is required. Common applications include weld blending, rust removal, edge deburring, and pre-paint surface conditioning. The Roloc TR quick-change system allows fast disc swaps without additional hardware, making it practical in production or service environments where multiple grits are cycled through during a single job. Trade professionals in sheet metal, HVAC fabrication, and general mechanical work commonly use this product with angle grinders and die grinders equipped with a compatible Roloc TR or Type R mandrel.
