3M 7010310150 Quick Change Disc 4 Inch Coarse Ao

Product Description

The 3M 7010310150 is a 4-inch aluminum oxide quick change surface conditioning disc designed for cleaning, blending, and finishing workpieces in a single pass. The RC (rapid change) nonwoven material breaks down under medium pressure to continuously expose fresh fibers and mineral, maintaining cut rate throughout the disc life. Its open-web construction responds to surface irregularities and resists loading from paint, corrosion, and soft metal debris. This disc is intended for use by metalworkers, fabricators, and finishing technicians who require efficient material removal and surface prep ahead of coatings or final finishes.

This disc is suited for flatwork, composite surfaces, and softer metals including aluminum. It performs well in blending, coating removal, light deburring, and general surface conditioning on flat workpieces. The coarse-grade brown disc provides aggressive initial cut and sustained cut rate across moderate-pressure applications. Quick change attachment allows fast disc swaps without additional hardware, improving throughput during production or repair work.

Key Features

• Aluminum oxide mineral on RC nonwoven material delivers good initial and extended cut rate
• Load-resistant construction reduces clogging from paint, corrosion, and soft metal swarf
• Open-web structure conforms to surface irregularities and minimizes gouging
• Cleans and finishes in a single step, reducing workpiece prep time
• Quick change attachment system enables fast disc swaps for improved tool efficiency
• Coarse grade suited for blending, coating removal, finishing, and light deburring on flat surfaces

Compatibility

Designed for use with quick change disc holders and right-angle grinders or die grinders that accept standard quick change (Type R) disc attachments. Suitable for use on composites, aluminum, and other soft metals on flat surfaces.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source. Verify that the quick change holder is rated for the disc diameter and operating speed before mounting. Inspect the disc for damage before each use and discard any disc that shows tears, uneven wear, or delamination. Follow applicable shop safety procedures including eye protection and proper RPM ratings as marked on the tool.
