3M 7000121850 Quick Change Disc 1.5 in Medium Ao

Product Description

The 3M 7000121850 is a quick change surface conditioning disc designed for one-step workpiece preparation ahead of final finishes and coatings. Built on a flexible, open non-woven web and reinforced with resin, the disc delivers consistent cut rates across a range of metals without gouging the substrate. At 1.5 inches in diameter and rated medium grade, it is suited for cleaning, deburring, and light surface prep where controlled aggression matters. Licensed technicians and fabricators working in light industrial and metal finishing environments will reach for this disc when both efficiency and finish quality are required on the same pass.

This disc is used across ferrous and non-ferrous metal applications, including aluminum and other soft metals where load resistance is critical. Its flexible web conforms well to flat surfaces and can handle some edgework. The medium-grade abrasive sits between the coarse and very fine offerings in this product line, making it a versatile choice for moderate industrial tasks such as cleaning scale, removing burrs, and preparing surfaces for primer or coating adhesion. Composites are also within its working range.

Key Features

• Medium-grade aluminum oxide abrasive balances cut rate and finish quality for moderate industrial applications
• Flexible open non-woven web removes burrs and surface contaminants without gouging the substrate
• Load-resistant construction performs reliably on aluminum and other soft non-ferrous metals
• Resin-reinforced fiber construction delivers consistent high cut rates throughout disc life
• Quick change attachment system allows fast disc swapping to reduce downtime at the tool
• Works on ferrous and non-ferrous metals as well as composites, primarily on flat surfaces and edgework

Compatibility

Designed for use with standard quick change disc holders and right-angle tools that accept 1.5-inch quick change discs across ferrous metals, non-ferrous metals, and composite substrates.

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from its power source. Verify that the quick change mandrel is rated for the disc diameter and operating speed before use. Always wear appropriate eye and hand protection when mounting abrasive discs or operating grinders. Follow applicable workplace safety standards for abrasive tool operation.
