Arc Abrasives 50410 Psa Disc 7 Inches Medium Grit

Product Description

The ARC ABRASIVES 50410 is a 7-inch pressure-sensitive adhesive (PSA) abrasive disc designed for fast attachment and removal from a compatible back-up pad. The Spiralcool R700 construction supports efficient material removal while helping manage heat buildup during extended use. Sold individually, this disc weighs 0.04 pounds and is suited for medium-grit finishing work across metalworking and woodworking applications. HVAC sheet metal fabricators, pipe fitters, and general trade professionals who require a reliable, quick-change disc for surface prep and blending will find this format practical on the job.

This disc is intended for use in metalworking, woodworking, light blending, and both contour and flat finishing operations. The PSA backing system allows the disc to mount directly to a standard PSA back-up pad without additional hardware, making it a common choice for technicians who swap discs frequently during a single job. It is appropriate for light material removal, surface conditioning, and finish preparation on flat or slightly contoured workpieces.

Key Features

• 7-inch diameter PSA disc for use with standard PSA back-up pads
• Medium grit rating suitable for light blending and surface finishing
• Spiralcool R700 construction to assist with heat dissipation during use
• Pressure-sensitive adhesive backing allows quick disc changes without tools
• Sold individually — compatible with high-volume single-disc replacement workflows

Compatibility

Designed as an OEM-style replacement or consumable disc for use with 7-inch PSA back-up pads on standard angle grinders and disc sanders configured for PSA-style abrasive discs.

Installation Notes

Installation requires a clean, dry PSA back-up pad surface — contamination or residue from a previous disc will reduce adhesion and disc life. Power down and disconnect the grinder or sander before mounting or removing the disc. Ensure the disc is fully seated and centered on the pad before resuming operation. Follow applicable ANSI B7 abrasive safety standards and wear appropriate PPE including eye and face protection.
