Arc Abrasives 3496706 Psa Disc 5 in 80 Grit Aluminum Oxide

Product Description

The ARC ABRASIVES 3496706 is a 5-inch PSA (pressure-sensitive adhesive) abrasive disc designed for fast attachment and removal from standard back-up pads. Coated with gold aluminum oxide stearate at 80 grit, this disc cuts aggressively on metal and wood surfaces while the stearate coating helps resist loading and heat buildup. The PSA backing eliminates the need for mechanical fasteners, making disc changes quick during production runs. It is suited for use by fabricators, woodworkers, and finishing tradespeople who need a reliable, repeatable abrasive in flat and contour applications.

This disc is well suited for metalworking, woodworking, light blending, and both contour and flat surface finishing. The 80-grit cut level makes it appropriate for moderate stock removal and surface preparation before finer finishing steps. It is commonly used in fabrication shops, millwork operations, and general-purpose finishing environments where operator efficiency and consistent scratch patterns matter.

Key Features

• PSA backing allows quick disc changes without tools or mechanical fasteners
• Gold aluminum oxide stearate abrasive resists loading on wood resins and soft metals
• 80 grit is suited for moderate stock removal and surface prep
• 5-inch diameter fits standard PSA back-up pads common in trade and production settings
• Sold individually, suitable for single-disc replacement or stocking in small quantities

Compatibility

Designed as a replacement or stock PSA abrasive disc for use with standard 5-inch PSA back-up pads used in metalworking and woodworking finishing applications.

Installation Notes

Ensure the back-up pad surface is clean and free of debris before applying the PSA disc, as contamination will reduce adhesion. Align the disc centered on the pad before pressing firmly to seat the adhesive. Remove the disc promptly after use to prevent adhesive transfer to the pad surface. Follow all tool manufacturer guidelines and applicable shop safety practices when operating disc sanders or grinders.
