Arc Abrasives 34973 Psa Disc 6 Inches 80 Grit

Product Description

The ARC ABRASIVES 34973 is a 6-inch PSA (pressure-sensitive adhesive) abrasive disc coated with gold aluminum oxide stearate at 80 grit. The stearate coating reduces loading and heat buildup during aggressive stock removal, extending disc life on both metal and wood surfaces. The PSA backing system allows fast attachment and removal from a compatible backup pad without tools, reducing downtime during disc changes. This disc is sold individually and is well suited for metal fabrication shops, woodworking operations, and finishing applications requiring a consistent fine cut.

This disc is designed for use in metalworking and woodworking environments where quick disc swaps and reliable adhesion to backup pads are priorities. Typical applications include light blending, contour finishing, and flat surface finishing on bare metal, painted surfaces, and wood. The 80-grit aluminum oxide stearate construction performs well on both ferrous and non-ferrous materials and resists loading when working softer materials such as hardwood or MDF.

Key Features

• PSA backing for tool-free attachment and removal from standard backup pads
• Gold aluminum oxide stearate abrasive mineral reduces loading and extends disc life
• 80 grit delivers aggressive material removal with a fine finish profile
• 6-inch diameter fits common random-orbit and disc sanders with PSA-compatible pads
• Suitable for metalworking, woodworking, blending, and flat or contour finishing

Compatibility

Designed for use with 6-inch PSA-compatible backup pads on random-orbit sanders, disc sanders, and angle grinders equipped with appropriate backing plates.

Installation Notes

Disc installation and removal requires no tools — press the PSA face firmly onto a clean, dry backup pad and peel to remove. Ensure the backup pad surface is free of debris or adhesive residue before mounting a new disc to maintain proper bond. Operators should wear appropriate PPE including eye protection and gloves when operating disc sanders. Follow all applicable workplace safety guidelines for abrasive tool use.
