Merit Abrasives 69957399705 Quick-change Disc 2in 24 Grit

Product Description

The MERIT ABRASIVES 69957399705 is a coated quick-change abrasive disc designed for aggressive material removal on metal surfaces. It features aluminum oxide abrasive on a Y-weight 2-ply polyester and cloth backing, giving it rigidity and durability under sustained use. The disc measures 2 inches in diameter, carries a 24-grit (extra coarse) rating, and is rated for a maximum of 30,000 RPM. It attaches via a Type R (TR / Type III Power-Lock) quick-change system, making it compatible with standard handheld disc sanders used in fabrication and finishing environments. Licensed HVAC techs, pipefitters, welders, and metalworkers reach for discs in this grit range for fast stock removal and surface prep.

This disc is suited for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is intended for handheld disc sander applications in both shop and field environments. The rigid backing and aluminum oxide abrasive make it especially effective for deburring, cleaning weld seams, and detailing on harder alloys where a more aggressive cut rate is needed. The brown disc and black button are consistent identifiers for the MERIT R766 series.
