Product Description

PDC Picks

PDC picks are widely, used lo, hard tunneling , 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 tungtsen 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.

The combination of the pick head and pick body applies the cold setting process.



Compared with common alloy picks, the advantages of PDC picks are:

Long service life
Reduce the quantity of the picks replacement
Reduce the use cost of the picks
Improve mining/excavating efficiency
Improve the utilization rate of equipment
Improve the reliability of the operation and reduce the labor intensity of workers


According to the long service life of PDC picks, the performance requirement of the pick sets and pick seats are higher, To get better performance of PDC picks, it is recommended to use our pick sets and pick seats.
