Diamond Pdc Button Round Shank Cutting Bits

Keeping track with market development, we are indulged in exporting, manufacturing and supplying an excellent quality spectrum of PDC Button Round Shank Cutting Bits in Wuhan, Hubei, China. PDC picks are widely used for hard tunneling excavation, coal mining (with coal gangue), complex geology, road milling, applied in construction of rotary drilling machines and dual milling equipment. When cutting coal rocks, picks will bear periodic high compressive stress, shear stress and impact load. At the same time, in such complicated conditions, due to friction and impact will cause pick temperature, the pick heads are required high wear resistance, good impact resistance, and excellent thermal stability. Compared with tungsten carbide inserts, PDC inserts have such excellent performances, and show higher cost efficiency advantage.

Technical Features
The pick body is made of molybdenum nickel alloy steel, with high strength, high hardenability, high toughness, small deformation, high temperature quenching. The pick steel use the special heat treatment, with high fatigue limit, high impact resistance, and good low-temperature impact toughness.
The pick head is PDC insert. Using HTHP process, the PDC head is with extremely wear resistance, excellent impact resistance and heat resistance, also with good heat conduction, corrosion resistance.
