3M 7100074858 Quick Change Buff and Blend Hs Disc 2 Inch

Product Description

The 3M 7100074858 is a Quick Change Buff and Blend HS Disc built for light deburring, surface cleaning, and final finishing on metal workpieces. It uses a high-strength non-woven nylon web impregnated with Aluminum Oxide mineral to cut consistently without gouging or smearing. The dense, stiff construction holds its shape under high contact pressure, making it reliable for edgework and irregular surface profiles. This disc is sized at 2 inches in diameter and mounts via a quick-change attachment for fast swapping between discs during production or repair work. It is used by metalworkers, fabricators, and finishing technicians in shop and field environments.

This disc is well suited for surface prep and finishing on both ferrous and non-ferrous metals in light manufacturing, metal fabrication, and maintenance applications. The open-web construction resists loading, so debris does not clog the abrasive face prematurely, extending usable disc life. It is available in three grades to match the required aggressiveness: Coarse (CRS, green), Medium (MED, blue), and Very Fine (VFN, maroon). Each grade produces a uniform, consistent scratch pattern appropriate to its finishing stage.

Key Features

Compatibility

Designed for use with standard quick-change disc holders and right-angle die grinders that accept 2-inch quick-change non-woven discs.

Installation Notes

Installation is performed by the operator or finishing technician using a compatible quick-change mandrel and a right-angle die grinder or similar rotary tool. Ensure the tool is powered off and disconnected from its air or electrical supply before mounting or removing the disc. Inspect the disc for damage before each use and do not exceed the tool or disc rated speed. Follow applicable shop safety protocols and wear appropriate PPE including eye protection and gloves.
