GCD20 – Metal Bond Crushed Diamond Grit

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

GCD20 is a stronger crushed diamond grit developed for metal-bond grinding tools requiring improved grain stability, controlled wear and longer abrasive life. Its stronger crushed structure provides greater resistance to premature breakdown than resin-bond-oriented grades while retaining the angular cutting geometry required for efficient material removal.

Features

Stronger Crushed Grain Structure: Provides improved resistance to premature abrasive breakdown.
Controlled Fracture Behavior: Maintains cutting activity while limiting excessive grain loss.
Improved Grain Stability: Supports longer abrasive life under sustained grinding loads.
Improved Wear Resistance: Suitable for metal-bond and selected vitrified grinding tools.
Consistent Mesh Distribution: Supports repeatable grinding and tool performance.
