Graphite milling, the proper way - EDM Sales & Supplies

Graphite is very abrasive due to its bond strength between individual carbon molecules. The only effective way to conquer graphite is using diamond coated tools. Generally, diamond coated tools can last 15-20 times longer then uncoated tools. But it also depends a lot on cutting conditions, machine tools and user requirement of surface quality.

Diamonds do not last forever. Diamonds degrade to graphite, because graphite is a lower-energy configuration under typical conditions. Diamond (the stuff in wedding rings) and graphite (the stuff in pencils) are both crystalline forms of pure carbon.

During the coating process, hydrogen molecules are dissociated from the carbon molecules deposited onto the tool, leaving a diamond matrix under the right temperature and pressure conditions. Under the wrong conditions, the tool may be simply coated in graphite. 6% cobalt carbide blanks allow for the best adhesion of diamond and a substrate.

Carbon - Wikipedia

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.

Allotropes of carbon - Wikipedia

Graphite, named by Abraham Gottlob Werner in 1789, from the Greek γράφειν (graphein, "to draw/write", for its use in pencils) is one of the most common allotropes of carbon.Unlike diamond, graphite is an electrical conductor. Thus, it can be used in, for instance, electrical arc lamp electrodes. Likewise, under standard conditions, graphite is the most stable form of carbon.

Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.In graphite the bonds are sp 2 orbital hybrids and the atoms form in planes with each bound to three nearest neighbors 120 degrees apart.
