CBN-A99 – Selected High-Integrity CBN Grit

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

CBN-A99 is a selected high-integrity monocrystalline CBN grit developed for demanding metal-bond, electroplated and single-layer abrasive tools. Selected blocky particles with controlled crystal morphology provide stable grain projection and wear behavior, making this grade suitable for applications where particle consistency, grain retention and tool profile stability are important.

Features

Selected High-Integrity Grains: Emphasizes consistent crystal quality and stable abrasive performance.
Controlled Blocky Morphology: Supports predictable grain projection and cutting geometry.
Stable Wear Behavior: Helps maintain consistent abrasive performance under sustained loading.
Retention-Oriented Grade: Suitable for metal-bond, electroplated and selected single-layer CBN tools.
