3M 7100142277 Quick Change Abrasive Disc 3 Inch

Product Description

The 3M 7100142277 is a 3-inch quick change surface conditioning disc designed for one-step workpiece preparation ahead of final finishes and coatings. Built on a tough, flexible non-woven open-web construction and reinforced with resin, this disc delivers consistent cut rates across a range of metalworking applications. The open web resists loading, making it a reliable choice for aluminum and other soft metals that tend to clog conventional abrasives. It is rated to 18,000 RPM and sold in units of each, with a minimum order quantity of 25 discs. Licensed tradespeople and metalworking technicians in fabrication, maintenance, and production environments are the primary installers.

This disc is suited for light-to-moderate industrial applications on ferrous metals, non-ferrous metals, and composites. Typical use cases include surface cleaning, deburring, and prep work on flat surfaces and some edgework before priming or coating. The quick-change attachment system speeds up disc swaps, reducing downtime during production runs. It performs well in both shop fabrication settings and field maintenance scenarios where surface prep quality directly affects coating adhesion and finish quality.

Key Features

• Flexible, open non-woven web resists loading on aluminum and other soft metals
• Resin-reinforced construction provides consistent cut rate and repeatable finish quality
• Rated to 18,000 RPM for use with standard quick-change right-angle tools
• Multi-purpose abrasive works on ferrous metals, non-ferrous metals, and composites
• Quick-change mounting system reduces disc swap time and improves tool efficiency
• Suitable for cleaning, deburring, and one-step pre-coating surface preparation

Compatibility

Designed for use with standard quick-change disc holders and right-angle die grinders that accept 3-inch quick-change abrasive discs.

Installation Notes

This disc is intended for use by trained metalworking technicians and fabricators familiar with abrasive tooling. Always confirm the tool spindle speed meets or exceeds the 18,000 RPM disc rating before mounting. Inspect the disc for damage before each use and ensure the quick-change mandrel is fully seated and locked before operating. Wear appropriate PPE including eye protection and gloves when performing grinding or surface conditioning work.
