Pferd 42758008 Quick-change Disc 2 in 120 Grit Diamond

Product Description

The PFERD 42758008 is a 2-inch coated abrasive quick-change disc designed for precision grinding, blending, and finishing on hard materials. The abrasive material is diamond, graded at D126, making it well suited for work on ceramics, carbide, glass, stone, and hardened steel where conventional aluminum oxide or zirconia abrasives wear too quickly. The disc mounts via a Type R attaching system for fast single-motion installation on compatible rotary tools and die grinders. Maximum rated speed is 7,500 RPM. The fiber backing provides dimensional stability under load, and the gray disc face resists loading on dense or vitrified surfaces.

This disc is intended for use in toolroom, maintenance, and fabrication environments where tight access and small-diameter abrasive work is required. At 2 inches in diameter, it fits die grinders and right-angle tools used by machinists, tool-and-die professionals, and industrial maintenance technicians. Typical applications include edge prep on carbide inserts, deburring hardened components, and surface blending on ceramic or glass substrates. The CDR quick-change compatibility allows rapid disc swaps during production or service work without additional hardware.

Key Features

• Diamond abrasive material rated at grade D126 for cutting hard and dense workpiece materials
• 2-inch disc diameter sized for die grinders and compact right-angle tools
• 120 grit provides a medium-fine finish suitable for blending and controlled material removal
• Type R attaching system enables single-motion mounting and removal
• Fiber backing delivers rigidity and resistance to deflection under lateral load
• Rated to 7,500 RPM maximum for safe operation within CDR-compatible tool speed ranges

Compatibility

Designed for CDR quick-change systems using a Type R attaching interface. Confirm the host tool accepts CDR Type R discs and does not exceed the 7,500 RPM maximum rated speed before use.

Installation Notes

Installation is performed by a qualified technician familiar with abrasive tooling and rotary equipment. Ensure the die grinder or right-angle tool is disconnected from the air supply or power source before mounting or removing the disc. Verify the tool spindle speed does not exceed 7,500 RPM. Inspect the disc for cracks, chips, or delamination before each use and discard any damaged disc immediately.
