How to choose the fit type cutting tools for the graphite machining?

Graphite and carbon products have excellent performance. The most widely used graphite is as EDM electrode material. It has high machinability, light weight, fast forming, 

minimal expansion rate, low loss and easy dressing. Widely used in die industry. Graphite has a low hardness and is a very easy material for cutting. However, when cutting 

graphite, the tool is very easy to wear and the graphite workpiece is easily broken.

Tool material is the fundamental factor determining the cutting performance of the tool, and has a great impact on machining efficiency, machining quality, machining cost and tool 

durability. In general, the harder the tool material is, the better its wear resistance, the higher the hardness, the lower the impact toughness, and the more brittle the material. LINKUT
