3M 7100142497 Quick Change Disc 3 Inch Ao 18000 Rpm

Product Description

The 3M 7100142497 is a Quick Change Surface Conditioning GP Disc designed for one-step workpiece preparation ahead of final finishes and coatings. Built on a flexible, open non-woven web reinforced with resin, the disc delivers consistent cut rates while remaining load-resistant, making it well suited for aluminum and other soft metals in addition to ferrous materials and composites. It operates at a rated speed of 18000 RPM and measures 3 inches in diameter. Licensed metalworkers, fabricators, and industrial maintenance technicians are the typical installers. The disc handles flat surface prep and moderate edgework without gouging the substrate.

This disc is used in general industrial metal fabrication and maintenance environments where surface conditioning, cleaning, and deburring are required before coating or finishing operations. Its multi-purpose abrasive construction makes it appropriate for both ferrous and non-ferrous metals as well as composite materials. The quick-change attachment system reduces downtime during disc swaps, supporting higher throughput in production and job-shop settings. Typical applications include weld seam blending, light deburring, and pre-paint surface preparation on flat workpieces.

Key Features

• One-step surface prep reduces handling time before coating or finishing
• Flexible, pliable open web removes burrs and surface contaminants without gouging
• Load-resistant construction performs reliably on aluminum and other soft non-ferrous metals
• Works on ferrous and non-ferrous metals and composites, on flat surfaces and moderate edgework
• Quick-change attachment system allows fast disc swaps to maintain tool efficiency
• Available in coarse (dark brown), medium (dark maroon), and very fine (dark blue) grades

Compatibility

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

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from its power source. Verify the tool's rated free speed meets or exceeds the 18000 RPM disc rating before mounting. Inspect the disc for damage before each use and discard any disc showing tears, cuts, or delamination. Follow applicable shop safety protocols and wear appropriate PPE including eye protection and gloves during grinding operations.
