Tru-maxx 69957323758 Quick-change Disc 36 Grit 3 in Tr

Product Description

The TRU-MAXX 69957323758 is a 3-inch diameter quick-change abrasive disc designed for high-speed grinding, blending, and surface preparation on metal and weld areas. It uses a zirconia alumina abrasive on a cloth backing, rated at a Y-weight backing for aggressive stock removal. At 36 grit, this disc falls in the very coarse grade range, making it well-suited for weld seam removal, rust stripping, and rapid material removal on ferrous and non-ferrous surfaces. It is rated for a maximum of 20,000 RPM and mounts via a Type R quick-change attaching system.

This disc is used in fabrication shops, welding operations, metal service centers, and maintenance facilities where frequent disc changes and consistent cut rates are required. The Type R mount allows tool-free disc swaps, reducing downtime on production grinding tasks. The coated blue zirconia alumina construction self-sharpens during use, maintaining cut rate over the life of the disc. Applications include weld blending, deburring, edge prep, and surface conditioning on structural steel and plate stock.

Installation Notes

Installation of quick-change abrasive discs is typically performed by grinding and fabrication professionals. Before mounting, confirm the tool spindle speed does not exceed the 20,000 RPM disc rating. Ensure the quick-change mandrel is clean and the locking mechanism is fully engaged before operating the tool. Always wear appropriate PPE including eye protection and gloves when performing grinding operations.
