Dewalt DALN1C121A Quick-change Disc 120 Grit 2 in

Product Description

The DEWALT DALN1C121A is a 2-inch coated abrasive quick-change disc designed for use with Roloc-style TR (Type III) attaching systems. Constructed with aluminum oxide abrasive at 120 grit, this fine-grade disc handles surface blending, deburring, light stock removal, and finish prep on metal and other hard substrates. It is rated to a maximum of 20,000 RPM, making it compatible with standard pneumatic and electric die grinders used in fabrication, maintenance, and metalworking applications. The coated construction delivers consistent cut rate across the disc face throughout the working life of the abrasive.

This disc is suited for light finishing and surface conditioning tasks in industrial, manufacturing, and general maintenance environments. Typical applications include weld spatter cleanup, edge blending, and surface preparation prior to coating or inspection. The TR (Type III) quick-change attaching system allows for fast disc swaps without tools, reducing downtime during production or field service work. The brown disc with white button is a standard indicator of the fine 120-grit aluminum oxide formulation. This product is sold as a single disc with a minimum order quantity of 100 units.

Installation Notes

Installation should be performed by a trained technician familiar with abrasive tool safety and applicable ANSI standards for coated abrasives. Before mounting, inspect the disc for damage and confirm the mandrel and tool are rated to at least 20,000 RPM. Secure the disc firmly onto the TR mandrel until the locking mechanism engages, and verify the guard is in place before operating the grinder. Always wear appropriate PPE including eye protection and gloves when working with abrasive discs.
