Tru-maxx 69957323731 Quick-change Disc 3 in 80 Grit

Product Description

The TRU-MAXX 69957323731 is a 3-inch quick-change abrasive disc designed for material removal, surface blending, and finishing on metal and other industrial substrates. It uses aluminum oxide as the abrasive material, a durable and widely available abrasive well suited for ferrous metals and general-purpose grinding tasks. The disc is rated to 20,000 RPM and uses a Type R attaching system for tool-free swaps on compatible right-angle grinders and die grinders. The cloth backing with X-weight construction provides flexibility and tear resistance under load. Grit is 80, placing it in the medium grade range for stock removal with moderate surface finish output.

This disc is suited for fabrication shops, maintenance and repair operations, and production grinding environments where fast disc changes and consistent cut rate matter. The Type R quick-change mount is common on pneumatic and electric angle grinders used in metal fabrication, weld blending, and surface prep work. The brown coated face and black button are standard for this disc family. Each unit is sold individually, though the minimum order quantity is 50 discs per order.

Installation Notes

Disc installation and removal should be performed with the grinder powered off and disconnected from the air supply or electrical source. Verify the grinder spindle speed does not exceed 20,000 RPM before mounting the disc. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of wear through to the backing. Follow ANSI B11 and OSHA 1910.215 general abrasive wheel safety guidelines during use.
