What are diamond cutting tools?
Diamond cutting tools are cutting or abrasive tools where diamond—either natural or synthetic—is the primary cutting medium.Although various materials such as carbide and high-speed steels are used as cutting tools, diamond tools have excellent "hardness" and "diffusion of heat" compared with these materials.Polished diamond tools can make "sharp cutting edge."
Diamond cutting tools with these characteristics provide superior precision, superior lifetime, and high performance for your work pieces.
But Diamond is not suitable for machining ferrous metals (steel, iron) at high temperatures because the carbon in diamond reacts with iron, causing rapid graphitisation and tool wear. For those materials, cubic boron nitride (CBN) is preferred.
What's the advantage of Diamond cutting tools?
The diamond cutting tool has become an indispensable tool in the modern cutting process, which is mainly shown in the following aspects:
-
Extreme hardness – Diamond tops the Mohs scale (10) and has the highest Vickers hardness, enabling it to cut materials like tungsten carbide, ceramics, stone, glass, and composites.
-
Superb wear resistance – Tool life is typically tens to hundreds of times longer than carbide, reducing tool changes and downtime.
-
Outstanding thermal conductivity – Diamond quickly dissipates heat from the cutting zone, protecting the tool and workpiece from thermal damage.
-
Low coefficient of friction – Reduces cutting forces, built-up edge, and improves surface finish.
-
Excellent edge sharpness and form stability – Single‑crystal diamond can be sharpened to an atomic‑scale edge, achieving mirror finishes and sub‑micron form accuracy in ultra‑precision machining.
-
High material removal rate – When used as an abrasive (grinding, sawing, drilling), diamond tools combine speed with long life.
-
Superior surface integrity – Produces minimal subsurface damage in hard‑brittle materials.
