Description
The MERIT ABRASIVES 69957399637 is a coated quick-change abrasive disc engineered for aggressive material removal on metal surfaces. It measures 2 inches in diameter and carries a 24-grit aluminum oxide abrasive, placing it in the extra coarse grade range. The disc mounts via a Power-Lock Type 2 (TS Type II) attaching system and is rated to a maximum of 30,000 RPM. A two-ply cloth and polyester backing provides rigid support, making this disc well suited for high-pressure deburring, surface cleaning, and weld cleanup work performed by machinists, fabricators, and metal finishing tradespeople.
This disc is intended for use with handheld disc sanders equipped with a TS (Type II) or Type S quick-change arbor. Compatible material applications include 300 Series Stainless, 400 Series Stainless, Aluminum, Brass, Bronze, Hard Carbon Steels, Soft Carbon Steels, and Titanium. Typical use cases include deburring cut edges, cleaning oxidized surfaces, blending welds, and detailing stainless steel components in fabrication shops, maintenance environments, and field service work.
