Merit Abrasives 66623340036 Quick-change Disc 80 Grit

Product Description

The MERIT ABRASIVES 66623340036 is a quick-change abrasive disc designed for surface preparation and finishing work on metals and composites. Built to the Roloc Type R attachment system, it mounts and releases quickly on compatible die grinders and inline grinders without tools. The disc measures 1.5 inches in diameter and carries an 80-grit aluminum oxide abrasive bonded to a flexible polyester backing using Clean Bond resin technology. That resin system delivers smear-free finishes, which matters when working on stainless steel or titanium where surface contamination causes problems. The medium-grade, high-loft nylon fiber construction extends disc life while maintaining a consistent cut rate across the workpiece.

This disc is suited for moderate material removal and surface prep on a range of metals and hard materials. Listed material applications include 300 Series and 400 Series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass and composites. Compatible machines include die grinders, handheld disc sanders, inline grinders, and straight grinders. The small 1.5-inch diameter makes it effective in tight spaces and contoured surfaces where larger discs cannot reach. It ships individually but carries a minimum order quantity of 100 units.

Installation Notes

Installation is performed by trade professionals or skilled operators using compatible Type R quick-change grinders.
