Pferd 42740001 Quick-change Disc 1 Inch 60 Grit Diamond

Product Description

The PFERD 42740001 is a 1-inch diameter diamond-coated quick-change abrasive disc designed for use with CD-style Type S attaching systems. This disc carries a 60-grit rating at Grade D251, making it suitable for aggressive stock removal and surface conditioning on hard or abrasive materials. The fiber backing provides rigidity and durability under load, and the disc is rated to 15,000 RPM for compatibility with standard die grinders and right-angle tools used in precision grinding and finishing applications. Licensed tradespeople and toolroom machinists are the primary installers and users of this disc type.

This disc is used in metalworking, toolroom, and maintenance-repair-operations environments where controlled material removal on hard surfaces is required. The 1-inch diameter suits confined grinding tasks, weld blending in tight areas, and surface prep work on hardened materials where conventional aluminum oxide or zirconia abrasives wear prematurely. The CD quick-change platform allows fast disc swaps without tools, reducing downtime during multi-step finishing operations.

Installation Notes

Installation and disc changes should be performed by qualified personnel following the tool and abrasive manufacturer guidelines. Ensure the grinder is powered off and disconnected from the power source before mounting or removing the disc. Confirm the tool RPM rating meets or exceeds the disc maximum speed of 15,000 RPM before operation. Always inspect the disc for damage before use and follow applicable ANSI B11 and OSHA abrasive wheel safety standards.
