Pferd 43243 Quick-change Disc 3 in 180 Grit Aluminum Oxide

Product Description

The PFERD 43243 is a 3-inch quick-change abrasive disc designed for surface finishing, blending, and deburring applications in metal fabrication and maintenance work. Built with aluminum oxide on a non-woven, cloth-backed construction, this disc delivers consistent medium-grade cutting action at up to 5,000 RPM. The CDR quick-change format uses a TR (Type III) attaching system, allowing fast disc swaps without tools. The maroon disc body with black button is a common format recognized by machinists, welders, and fabricators who need repeatable surface prep results across steel and other ferrous metals.

This disc is suited for light to medium material removal, surface blending, and scratch removal on flat or contoured surfaces. It is commonly used in shop environments by metal fabricators, maintenance technicians, and welders performing weld blending, scale removal, and pre-paint prep. The non-woven construction conforms slightly to irregular surfaces, making it useful on edges and contours where rigid discs would skip or gouge.

Compatibility

Designed for use with CDR quick-change tool holders and angle grinders or die grinders fitted with a TR (Type III) quick-change adapter. Confirm that the host tool and adapter are rated for at least 5,000 RPM before use.

Installation Notes

Installation requires a TR (Type III) quick-change mandrel mounted in a compatible die grinder or angle grinder. Power down and disconnect the tool from its air or electrical supply before changing discs. Verify the tool spindle speed does not exceed the 5,000 RPM disc rating. Inspect the disc for damage before each use and do not use damaged or delaminated discs.
