3M 7010029943 Sanding Disc 5 Inch P400 Grit Aluminum Oxide

Product Description

The 3M 7010029943 is a coated abrasive hook-and-loop sanding disc engineered for dust-managed surface finishing applications. Measuring 5 inches in diameter and rated at P400 grit, this disc uses aluminum oxide abrasive grain and a multi-hole pattern designed to evacuate sanding dust more efficiently than standard 5- or 6-hole disc configurations. The open-coat, load-resistant construction resists clogging during use. Rated to 12,000 RPM, the disc pairs with random orbital and disc sanders equipped with hook-and-loop backup pads used in finishing trades, body work, and light industrial applications.

This disc is suited for fine finish sanding on wood, composites, and painted or primed surfaces where consistent surface preparation is required before topcoating. The multi-hole dust extraction pattern works without requiring alignment to the backup pad holes, which speeds up disc changes during continuous production or repair work. The film backing resists tearing under normal operating conditions, supporting repeated attach-and-release cycles over the life of the disc.

Key Features

• Multi-hole pattern evacuates dust more effectively than 5- or 6-hole designs, extending disc life and maintaining cut rate
• No hole alignment required with backup pad, allowing fast and easy disc changes
• Open-coat, load-resistant construction reduces clogging on resinous or painted surfaces
• Aluminum oxide grain cuts faster and outlasts traditional garnet abrasives
• Durable film backing is tear-resistant and supports consistent, close-tolerance finishing
• Hook-and-loop attachment for quick removal and reuse across compatible disc pads

Compatibility

Designed for use with 5-inch hook-and-loop backup pads on random orbital sanders and finishing sanders rated for sanding disc use up to 12,000 RPM.

Installation Notes

This disc is installed and removed by hand on a hook-and-loop backup pad — no tools required for disc changes. Verify the sander's maximum RPM rating meets or exceeds the disc rating before use. Inspect the backup pad for worn or contaminated hook material before attaching a new disc, as a degraded pad reduces holding force at speed. Follow applicable workplace safety guidelines for abrasive tool use, including eye and respiratory protection.
