3M 7010292751 Quick Change Disc 2 in Extra Coarse Ao

Product Description

The 3M 7010292751 is a quick change surface conditioning disc designed for single-step cleaning and finishing of workpieces prior to final coatings or finishes. Built on an RC open-web material with aluminum oxide mineral, it delivers consistent cut rate at initial contact and maintains that rate as the disc is used. The RC web breaks down progressively under medium pressure, continually exposing fresh mineral and fiber. Its load-resistant construction resists clogging from paint residue, rust, and corrosion byproducts, keeping the disc cutting cleanly through the work.

This disc is suited for use on flat surfaces, composite materials, and softer metals including aluminum. Typical applications include blending, coating removal, light deburring, and surface finishing in fabrication, automotive body, and general metalworking environments. The quick change mounting system allows fast disc swaps without tools, reducing downtime during production or repair work. The extra coarse grade is supplied in dark brown and is best matched to moderate-pressure general use where aggressive material removal is needed before finer finishing steps.

Key Features

• Aluminum oxide mineral on RC open-web material for good initial and sustained cut rate
• RC web breaks down under medium pressure to expose fresh fibers and mineral
• Load-resistant construction reduces clogging from paint and corrosion
• Open web conforms to surface irregularities and minimizes gouging
• Quick change attachment system for fast, tool-free disc swapping
• Extra coarse grade in dark brown for aggressive material removal on flat surfaces

Compatibility

Designed for use with standard quick change disc holders and right-angle grinders or die grinders equipped with a compatible quick change mandrel. Suitable for flatwork, composites, and softer metals such as aluminum.

Installation Notes

Installation and disc changes are performed by qualified metalworkers or fabricators using a compatible quick change mandrel. Power down the grinder and disconnect it from the power source before mounting or removing a disc. Verify the mandrel and spindle rating match the tool RPM before operation. Wear appropriate eye and hand protection during use and disc changes.
