Pferd 42740006 Diamond Quick-change Disc 220 Grit 1-1/2 in

Product Description

The PFERD 42740006 is a 1-1/2 inch diameter diamond-abrasive quick-change disc designed for precision surface finishing and material removal on hard or abrasive substrates. It runs a 220 grit diamond abrasive bonded to a fiber-backed coated construction, providing consistent cut and finish on materials that would rapidly wear conventional aluminum oxide or zirconia discs. The disc uses a Type S attaching system for CD-compatible quick-change holders, allowing fast one-handed swaps without additional tools. Rated to 10,000 RPM, it is suitable for use in right-angle die grinders and similar rotary tools. Licensed trades and finishing specialists working on ceramics, carbide, glass, or similar hard materials will find this disc well-suited to tight-tolerance deburring and blending work.

This disc is intended for applications where conventional abrasives fall short, including finish grinding on tungsten carbide tooling, ceramic components, hardened steel, and composite materials. The small 1-1/2 inch diameter makes it particularly useful in confined areas or on detailed workpieces where a larger disc cannot reach. It is commonly used by toolroom machinists, maintenance technicians, and trade professionals performing precision refacing or edge preparation work. The 220 grit grade delivers a fine finish cut appropriate for final-stage material removal rather than aggressive stock removal.

Key Features

• 220 grit diamond abrasive for fine finishing on hard and abrasive materials
• 1-1/2 inch disc diameter suited for detail work and confined-space applications
• CD quick-change compatibility with Type S attaching system for tool-free disc changes
• Fiber backing provides rigidity and dimensional stability during use
• 10,000 RPM maximum speed rating for use with standard die grinders
• Grade D76 diamond abrasive construction for extended service life on hard substrates

Compatibility

Compatible with CD-style quick-change disc holders using a Type S attaching system. Designed for use in right-angle die grinders and rotary tools that accept 1-1/2 inch Type S quick-change accessories.

Installation Notes

Installation and disc changes should be performed with the grinder fully powered off and disconnected from its power source. Verify that the holder and attaching button are in good condition before mounting the disc. Always confirm the tool RPM rating does not exceed the 10,000 RPM maximum marked on the disc. Operators should wear appropriate eye and face protection when using coated abrasive discs on hard materials.
