Description

The MERIT ABRASIVES 08834166368 is a quick-change abrasive disc engineered for surface finishing and blending on a wide range of metals and composites. Built with aluminum oxide grain bonded in resin to a flexible non-woven nylon fiber backing, this disc delivers a smooth cut rate and a consistent, uniform finish without aggressive material removal. The TR (Type III) / Type R attaching system allows fast, tool-free disc swaps on compatible quick-change mandrels. At a 1.5-inch diameter and rated to 30,000 RPM maximum, it is well suited to tight-access work where larger discs cannot reach.

This disc is intended for use on die grinders, inline grinders, straight grinders, and handheld disc sanders in metalworking, fabrication, and finishing applications. It performs across a broad range of material types including 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass or composite substrates. The medium grade and non-woven construction make it a practical choice for deburring, blending weld seams, and surface conditioning where maintaining base material integrity matters.

Compatible with a broad material range including stainless steels, carbon steels, titanium, super alloys, and composites

Compatibility

Designed for use with die grinders, inline grinders, straight grinders, and handheld disc sanders equipped with TR (Type III) or Type R quick-change mandrels. Rated for material applications including 300 Series Stainless, 400 Series Stainless, Fiberglass and Composites, Hard Carbon Steels, Soft Carbon Steels, Super Alloys, Titanium, and Tool Steels.

Installation Notes

Installation and disc changes should be performed only with the tool powered off and disconnected from its air or electrical supply. Confirm the mandrel type is TR (Type III) or Type R compatible before mounting. Do not exceed the 30,000 RPM maximum rated speed marked for this disc. Inspection of the disc for tears or damage before each use is standard practice in abrasive safety programs consistent with ANSI B7 guidelines.
