Drilling tool is the main part of drilling equipment, its main function is to break rock and form borehole. Rotary drilling tool is widely used in the oil industry. Driven by machinery, the rotary drilling tool will rotate, which will drive the whole drill tool to produce centripetal movement. The rock will be cracked and broken by cutting and grinding, which will play a role in downward drilling.

HCVAC coating equipment is developed for the hard film of drilling tools. The design of the working frame can maximize the number of products per furnace, and the turret adopts the lower transmission structure. The anode layer ion source with international advanced level and planar rectangular arc source with domestic leading level are adopted. It has multi-channel feedback control system, arc source control, gas path control, process control and unique octahedral cavity design, which not only improves the equipment space utilization rate, but also facilitates maintenance and repair.
