Pferd 42740010 Quick-change Disc 3 in 60 Grit Diamond

Product Description

The PFERD 42740010 is a 3-inch quick-change abrasive disc designed for aggressive material removal on hard surfaces. This coated diamond disc runs on a Type S attaching system, making it compatible with standard quick-change disc holders used across metalworking, stone, and composite finishing applications. At 60 grit, it falls in the coarse range, suited for rapid stock removal, weld blending, and surface prep rather than fine finishing. The disc carries a Grade D251 designation and is backed with fiber for durability under sustained grinding pressure. Maximum operating speed is 5,000 RPM. Weight is 0.1 pounds. Qualified metalworking technicians and fabricators are the primary installers.

This disc is used in applications requiring fast cutting action on hard or abrasive-resistant materials. The diamond abrasive grain makes it effective on ceramics, carbide, glass, stone, concrete, and similar hard substrates where aluminum oxide or zirconia grains wear quickly. The gray disc face and silver button are standard visual identifiers for this product line. It is sold and packaged as a single disc, appropriate for spot repairs, toolroom work, or evaluation before bulk ordering.

Installation Notes

Installation is performed by metalworking technicians or fabricators using a compatible Type S quick-change holder. Verify that the grinder spindle speed does not exceed the 5,000 RPM disc rating before mounting. Inspect the disc for damage before each use and replace if cracking, fraying, or delamination is present. Always wear appropriate eye and face protection when operating abrasive discs.
