3M 7000000385 Quick-change Disc 2 in 100 Grit Aluminum Oxide

Product Description

The 3M 7000000385 is a coated abrasive quick-change disc designed for use with Roloc TR and Type R style disc holders. Constructed with aluminum oxide abrasive grain bonded to a polyester cloth backing, this disc delivers consistent material removal on metal surfaces. At 100 grit, it falls in the fine grade range, making it well-suited for blending, light deburring, and surface prep work before finishing. The disc measures 2 inches in diameter and is rated for a maximum of 25,000 RPM. It is part of the 3M 361F Series and features a blue button attachment for quick mounting and release.

This disc is intended for use on metals including steel, aluminum, and similar substrates in fabrication, maintenance, and repair applications. Its small 2-inch diameter makes it effective in tight or contoured areas where larger discs cannot reach. The quick-change attachment system allows for fast disc swaps without tools, reducing downtime in production or field service environments. It is commonly used by metal fabricators, maintenance technicians, welders, and industrial service professionals.
