3M 7010330799 Surface Conditioning Disc 2 in Very Fine

Product Description

The 3M 7010330799 is a Standard Abrasives Surface Conditioning RC Disc designed for deburring, blending, cleaning, and finishing work on composites and soft metals. Built on a reinforced composite (RC) backing, this 2-inch diameter disc delivers high edge durability and consistent flexibility across its service life. The aluminum oxide abrasive grain provides strong initial cut rate that holds through extended use, making it a reliable choice for general surface prep tasks at up to 8,000 RPM. It attaches via a hook-and-loop system for fast changeovers. The Very Fine grade suits finishing and light blending rather than aggressive stock removal.

This disc is suited for metalworking and composite finishing applications in both shop and field settings. It performs best on flat surfaces where uniform contact can be maintained. Typical uses include coating removal, surface blending, and finish preparation on aluminum, fiberglass, and similar soft or non-ferrous materials. It is commonly used by fabricators, bodywork technicians, and maintenance professionals working with light-gauge metals and composite panels.

Key Features

• Aluminum oxide grain on RC backing for good initial and extended cut rate
• High edge durability and flexibility for consistent performance across the disc surface
• Very Fine grade suited for blending, finishing, and light deburring
• Hook and loop attachment system allows fast disc changes
• Rated to 8,000 RPM maximum operating speed
• Most efficient on flat surfaces of composites and soft metals

Compatibility

Designed for use with 2-inch hook-and-loop backup pads compatible with standard right-angle grinders and die grinders rated for 8,000 RPM or higher. Optimized for composites and soft metals including aluminum and fiberglass.

Installation Notes

This disc is installed and changed by fabricators or surface finishing technicians using compatible rotary tools. Before mounting, confirm the backup pad and tool spindle are rated for at least 8,000 RPM and that the hook-and-loop surface on the pad is clean and undamaged. Do not exceed the maximum rated speed. Inspect the disc for tears or delamination before each use and discard any damaged discs immediately.
