What are Diamond Cutting Tools?
Generally, diamond Cutting Tools or PCD cutting tools can cut aluminum, brass and copper, graphite, and other materials like wood, plastic, and carbon-fiber-reinforced polymer (CFRP).
Basically, diamond insert cutting tools are used to obtain high abrasive resistance and high hardness. Also, these motives result in a longer life for the cutter in comparison to conventional cutters.
Moreover, they can be customized to fit your exact measurement specifications for high precision.
What is CBN Cutting Tool?
Polycrystalline Carbon Boron Nitride (PCBN) or known as CBN cutting tools have high resistance to heat abrasion that is perfect for fine finishing and effective for tolerance control. They are also suitable for iron, cast iron, sintered material, and other hardened materials (HRC50 and above).
Furthermore, PCBN cutting tools are typically applied with inserts and round tools which include endmills, reamers and boring tools. Whereas, CBN tools can help reduce the production costs due to more efficient process of turning and milling.

Why are diamonds used in industrial cutting?
Basically, one of the most significant reasons you need to know why diamond insert tools are famous in industrial cutting is their hardness.
Which also means they consist of small particles of industrial-grade diamonds that are perfect as embedment in saw blades, grinding wheels and drill bits.
