Tru-maxx 69957323743 Quick-change Disc 1 in 120 Grit

Product Description

The TRU-MAXX 69957323743 is a quick-change abrasive disc designed for surface preparation, blending, and finishing on metal and other hard materials. This 1-inch diameter disc uses a zirconia alumina abrasive grain, which is a self-sharpening material well suited to aggressive stock removal and consistent cut rate over the life of the disc. At 120 grit, it falls in the fine grade range, making it appropriate for finishing passes, light deburring, and surface conditioning work. The cloth backing with Y-weight construction provides durability and flexibility under load. It attaches via a Type R quick-change system, allowing fast disc swaps without additional tools. Licensed tradespeople and fabricators in metal shops, HVAC fabrication, and maintenance environments are the primary users.

This disc is used in applications where a compact 1-inch abrasive is needed on a quick-change mandrel tool, such as detail grinding, weld blending in tight areas, or surface prep on tubing and sheet metal components. The fine 120 grit makes it suitable for work where surface finish quality matters after rough grinding is complete. It is sold individually but carries a minimum order quantity of 100 units, making it a consumable stocked in bulk by shops with ongoing grinding operations.
