Introduction

Super abrasives like CBN (Cubic Boron Nitride) and Diamond have revolutionized precision grinding in high-performance industries. But choosing the right one is not always straightforward — it depends on the material you’re working with, surface requirements, and cost-efficiency.

What Is CBN?

CBN is second only to diamond in hardness and is chemically stable at high temperatures — especially when machining ferrous materials like hardened steel.

Best for:

Hardened steel
Cast iron
Tool steels
Inconel

What Is Diamond Abrasive?

Diamond abrasives offer the highest hardness and are ideal for non-ferrous materials, composites, ceramics, and glass.

Best for:

Carbide tools
Glass and ceramics
Graphite
Tungsten and silicon
