Pferd 42740002 Quick-change Disc 1 in 120 Grit Diamond

Product Description

The PFERD 42740002 is a 1-inch diameter quick-change abrasive disc engineered for precision grinding and surface finishing with a diamond abrasive material rated at 120 grit (Grade D126). Designed for Type S attachment systems and CD quick-change compatibility, this coated disc features a fiber backing that provides stability and consistent cut under repeated use. With a maximum operating speed of 15,000 RPM, it is suited for demanding material removal and finishing tasks on hard or abrasive workpiece materials. Licensed trades and skilled fabricators use this disc in applications where controlled stock removal and fine surface prep are required.

This disc is used in metalworking, fabrication, and surface preparation applications where a compact 1-inch format is needed to access tight areas or perform detail work. The coated diamond abrasive construction makes it appropriate for finishing hard materials such as carbide, ceramics, hardened steel, and similar substrates. It is compatible with Type S quick-change backing pads and CD-style disc holders, allowing fast disc swaps without tools. Typical users include machinists, tool and die technicians, and precision fabricators working with angle grinders or rotary die grinders equipped with compatible quick-change systems.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive disc safety and rotary tool operation. Before mounting, ensure the tool is powered off and disconnected from its power source. Verify the backing pad and spindle are rated to meet or exceed the 15,000 RPM maximum disc speed. Inspect the disc for damage before each use and never exceed the rated RPM marked on the disc or its packaging.
