Pferd 42740003 Quick-change Disc 220 Grit 1 Inch

Product Description

The PFERD 42740003 is a 1-inch diamond-coated quick-change abrasive disc designed for precision grinding and finishing on hard materials. It carries a 220 grit rating and Grade D76 classification, making it well suited for fine material removal and surface prep on ceramics, carbide, glass, and hardened steel. The disc connects via a Type S attaching system and is compatible with CD-style quick-change holders. At a maximum rated speed of 15,000 RPM, it delivers consistent performance on die grinders and rotary tools used in tool-and-die, fabrication, and maintenance applications.

This disc is intended for professional use in environments where hard or brittle workpiece materials demand diamond abrasive rather than conventional aluminum oxide or ceramic grain. Typical applications include deburring, edge radiusing, and surface conditioning on hardened components. The small 1-inch diameter allows access to tight geometries, cavities, and contoured surfaces that larger discs cannot reach. It is commonly used by tool-and-die makers, machinists, and maintenance technicians working with precision components.

Key Features

• 220 grit diamond abrasive for fine finishing on hard materials
• 1-inch disc diameter for access to tight spaces and contoured surfaces
• Type S attaching system for secure, tool-free disc changes
• CD quick-change compatibility for use with standard CD-style holders
• 15,000 RPM maximum rated speed
• Fiber backing material for durability under rotary load

Compatibility

Designed for use with CD quick-change disc holders equipped with a Type S attaching system, as specified by the manufacturer.

Installation Notes

Installation is performed by a machinist or maintenance technician using a compatible CD-style quick-change holder. Before mounting or removing any abrasive disc, ensure the rotary tool or die grinder is powered off and fully stopped. Verify the tool spindle speed rating meets or exceeds 15,000 RPM before use. Inspect the disc for damage before each use and never exceed the rated maximum RPM.
