3M 7000121847 Quick Change Disc 1 Inch Very Fine Ao

Product Description

The 3M 7000121847 is a Quick Change Surface Conditioning GP Disc designed for one-step workpiece preparation ahead of final finishes and coatings. Built on a non-woven, resin-reinforced open web construction, the disc delivers a consistent cut rate while remaining flexible enough to follow flat surfaces and light edgework. At 1 inch in diameter and rated Very Fine grade with an Aluminum Oxide abrasive, it suits moderate material removal tasks where a controlled surface profile is required. Licensed trades and metalworking technicians use it with quick-change mandrel tools on standard pneumatic or electric angle grinders.

This disc is suited for work on ferrous and non-ferrous metals as well as composites, making it a practical choice across fabrication, maintenance, and finishing operations. Its load-resistant construction makes it especially effective on aluminum and other soft metals that typically clog conventional abrasive media. Typical applications include cleaning, deburring, and surface conditioning prior to coating or inspection on flat workpiece surfaces.

Key Features

• Very Fine Aluminum Oxide abrasive for controlled surface conditioning without aggressive stock removal
• Non-woven open web construction resists loading on aluminum and other soft metals
• Flexible, pliable disc follows flat surfaces and contours without gouging the substrate
• Quick-change attachment allows fast disc swapping to reduce tool downtime
• Works on ferrous metals, non-ferrous metals, and composites in a single disc type
• Resin-reinforced construction provides consistent cut rate across the service life of the disc

Compatibility

Designed for use with standard quick-change mandrel systems on pneumatic and electric rotary tools. Compatible with ferrous and non-ferrous metals and composites. Sold in units of each; minimum order quantity is 50 units.

Installation Notes

Installation and disc changes should be performed with the tool powered off and air supply disconnected. Verify the mandrel rating meets or exceeds the maximum RPM of the disc before mounting. Wear appropriate PPE including eye protection and gloves when operating rotary abrasive tools. Inspect the disc for tears or damage before each use and discard any disc showing visible wear through to the mandrel contact area.
