Merit Abrasives 08834166241 Quick-change Disc Tr 3/4 in

Product Description

The MERIT ABRASIVES 08834166241 is a non-woven aluminum oxide quick-change disc designed for surface preparation and finishing work on metal and composite materials. Built on a flexible polyester backing with a Type III TR attaching system, this 3/4-inch diameter disc operates at up to 40,000 RPM and delivers a medium-grade, 80-grit cut. It uses Clean Bond resin technology to resist smearing and loading, which keeps the disc cutting cleanly through the work cycle. Licensed technicians and metalworkers in fabrication and maintenance environments install this disc for deburring, blending, and surface conditioning tasks where a controlled, consistent finish is required.

This disc is suited for work on 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass or composite materials. The high-loft nylon fiber construction extends working life compared to standard coated abrasives. Compatible machines include die grinders, handheld disc sanders, inline grinders, and straight grinders — making it a practical choice for both shop and field service applications where compact abrasive tooling is needed.

Installation Notes

Installation requires a compatible die grinder or straight grinder fitted with a Type R quick-change mandrel. Verify the tool spindle speed does not exceed the 40,000 RPM disc rating before mounting. Power down and disconnect the tool from the air or electrical supply before changing discs. Always confirm the disc is fully seated on the mandrel button before resuming operation.
