Merit Abrasives 66623340043 Quick-change Disc 150 Grit

Product Description

The MERIT ABRASIVES 66623340043 is a TS Type II quick-change disc designed for surface preparation and finishing work on metal and composite materials. Measuring 3/4 inches in diameter, this disc uses aluminum oxide abrasive grain on a flexible polyester and nylon web backing rated for up to 40000 RPM. The non-woven construction and Clean Bond resin technology deliver smear-free finishes without loading the surface. Graded very fine at 150 grit, it is suited for light stock removal and surface conditioning on demanding materials. Licensed tradespeople performing precision metalwork will find this disc appropriate for controlled finishing passes where surface quality matters.

This disc is part of the Merit Surface Prep series and is designed for use on 300 series stainless, 400 series stainless, fiberglass and composites, hard carbon steels, soft carbon steels, super alloys, titanium, and tool steels. It is compatible with die grinders, handheld disc sanders, inline grinders, and straight grinders. The TS Type II attaching system with a silver button provides a secure, tool-free disc change in shop and field environments. The high-loft nylon fiber construction extends disc life under repeated use conditions.
