Pferd 42740012 Quick-change Disc 220 Grit Diamond 3 in

Product Description

The PFERD 42740012 is a 3-inch diamond-coated quick-change abrasive disc engineered for precision material removal and surface finishing on hard or abrasive workpieces. It carries a 220 grit diamond abrasive bonded to a fiber-backed disc in a coated construction. The disc mounts via a Type S attaching system with CD quick-change compatibility, spinning up to a rated maximum of 5,000 RPM. It is sized for angle grinders and die grinders equipped with a compatible Type S mandrel. Metalworkers, fabricators, and toolroom technicians are the primary users of this disc in both shop and field settings.

This disc is suited for grinding, blending, and finishing operations on extremely hard materials such as carbide, ceramics, glass, stone, and hardened steel where conventional abrasives wear too quickly. The 220 grit rating positions it for fine stock removal and surface refinement rather than aggressive material takedown. It fits compact right-angle grinders and pneumatic die grinders used in production, maintenance, and repair environments. The single-disc package format supports job-specific selection and controlled inventory management on the shop floor.

Installation Notes

Installation is performed by grinding equipment operators and toolroom technicians. Ensure the grinder is powered off and disconnected from its power source before mounting or removing the disc. Verify that the tool spindle speed does not exceed the 5,000 RPM disc rating before operation. Inspect the disc for cracks or damage prior to each use and follow applicable ANSI B7.1 safety standards for the use of abrasive products.
