3M 7000122089 Quick Change Disc 1.5 in Aluminum Oxide Coarse

Product Description

The 3M 7000122089 is a Standard Abrasives Quick Change Surface Conditioning RC Disc designed for surface prep work on flat workpieces. It combines cleaning and finishing into a single step, reducing the time needed before applying final finishes or coatings. The disc is built on an open-web RC material that breaks down under medium pressure to expose fresh aluminum oxide fibers and mineral, maintaining cut rate throughout the disc's life. The load-resistant construction resists clogging from paint buildup and corrosion residue, making it a practical choice for metalworking and composites applications. Installed by fabricators, maintenance technicians, and metal finishing professionals.

This disc is suited for use on flat surfaces including composites and softer metals such as aluminum. Typical applications include blending, coating removal, light deburring, and surface finishing ahead of priming or painting. The open-web structure responds to minor surface irregularities and reduces the risk of gouging the workpiece. The coarse-grade aluminum oxide formulation delivers consistent cut performance at moderate pressure without excessive loading.

Key Features

• Aluminum oxide abrasive on RC open-web material provides sustained initial and extended cut rate
• Load-resistant construction reduces clogging from paint and corrosion during use
• Open web conforms to surface irregularities and minimizes gouging on flat work
• Coarse grade rated for blending, coating removal, finishing, and light deburring
• Well-suited for composites and soft metals including aluminum
• Quick-change attachment system allows fast disc swapping to maintain tool efficiency

Compatibility

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

Installation Notes

Installation and disc changes should be performed with the tool unplugged or air supply disconnected. Verify the quick-change mandrel is the correct size and rated RPM for this disc before mounting. Inspect the disc for damage before each use and do not exceed the tool's rated speed. Always wear appropriate eye and hand protection when operating abrasive discs.
