Description

The MERIT ABRASIVES 69957399773 is a 2-inch coated quick-change abrasive disc designed for rapid material removal and weld blending on metal surfaces. It uses a premium aluminum oxide grain bonded to a rigid Y-weight 2-ply polyester backing, which resists tearing under aggressive grinding conditions. The Power-Lock Type 1 (TP) attaching system allows fast disc swaps on compatible handheld disc sanders without additional hardware. At 24 grit, this disc is rated extra coarse and is built for high-stock-removal tasks in moderately demanding fabrication and finishing environments. Licensed trades including metal fabricators, pipefitters, and maintenance welders are the primary users.

This disc is suited for use on a handheld disc sander in both shop and field applications. The 24-grit aluminum oxide construction performs well on ferrous and non-ferrous metals, making it a practical choice for weld blending, surface prep, and stock removal operations across a wide range of base materials. The special grain coating extends disc life and maintains cut rate through extended use cycles.

Installation Notes

Disc installation and removal should be performed with the tool powered off and disconnected from its power source. Verify that the tool spindle speed does not exceed the 30,000 RPM maximum disc rating before operation. Inspect the disc for cracks, tears, or delamination before each use and discard any damaged disc immediately. Follow applicable ANSI B7.1 safety guidelines for abrasive disc use and wear appropriate PPE including face shield and gloves.
