The Extended Shank tools combine a short flute length for maximum rigidity with a long shank for reaching into deep cavities. When the extended shank is not required, you can choke up on the tool to make it extremely rigid as a stub tool.

Crystallume DCC rotating tools were first developed in an NIST (National Institute of Science and Technology) program that involved a research partnership with Boeing Aircraft and three other large manufacturing companies. Some of the information gained in that program is presented below.

The material was 8-276 carbon fiber laminate 0.30 thick. Test tools were 0.251 diameter drill countersinks. The graph compares the number of holes drilled versus the thrust required. The test was concluded at 50 lbs. of thrust when breakout and haloing became unacceptable. Carbide lasted about 200 holes, PCD lasted 1, 500 holes and Crystallume DCC lasted 2, 700 holes. Also, note that the sharper carbide tool started with the lowest thrust while the PCD and Crystallume DCC started with about the same thrust (even though the PCD is a ground edge and the Crystallume DCC is a coated, faceted edge). These test lab results were repeated on the production floor.

Crystallume DCC tools are finding rapid acceptance among manufacturers of graphite electrodes for use in EDM operations because they last 10 to 30 times as long as carbide tools currently used. Increased tool life results in longer periods of unmanned machining. The machining speeds for Crystallume DCC tools can be increased 2 to 3 times over the speeds used with carbide tools to increase your productivity. These features combine to increase the utilization of your machine tools.

The 0.500 Replaceable Tip End Mill is intended to be held in a heat shrink holder and give you 4 and 6 flute productivity as compared to the 2 flutes available from insert end mills this size. Depending on your application several configurations are currently available from stock.

Standard DCC Drills are 2 flute with a 118, 4 facet drill point and come in jobbers lengths. The diamond coating extends a minimum of one diameter from the drill tip on the jobber drills and past the counter sink on center drills. DCC drills are available as specials in sizes from 0.028 to 0.750. Metric sizes are available as well.

The ThunderBolt Ultra Thin Nano Diamond Tools have a real diamond coating that is the thickness of most PVD coatings. The performance of real diamond, along with the edge sharpness of a thin coating, gives unheard of performance in the finishing of graphite. It is also the perfect tool for rib machining on graphite electrodes.

They allow longer periods of unmanned machining at increased machining speeds.

Crystallume offers the most consistent diamond tool available for electrode and mold manufacturing. These tools are available in 2 and 4 flute, standard and metric sizes.

The Lightning Series of tools are a cost-effective solution for the machining of graphite electrodes. By reducing the coating thickness, the edge sharpness is increased and the cost reduced. These tools are a great solution for medium-lot size jobs.
