What is the difference between PDC 2Wing anchor shank drill bit and PDC 3Wing anchor shank drill bit May 17, 2017

PDC 2 Wing drillefficiency could be improved efficiently in hard terrane (sandstone).The PDC disks are wearable and of high impact resistance,do not need to repair anymore and made the bit’s service life extended.

 

The bit makes less shrinking and high high success ratio hole,save the test drill pipe,improve the efficiency of construction as well as reduce the miners’ labour intensity.

 

PDC anchor shank drill bit wildly applied in all kind of terrane,can be applied in the terrane of f≤12.

 

PDC 3Wing anchor shank drill bit possess of perfect stability in drilling process,the PDC disks hardly damaged.The bit makes less shrinking and high success ratio hole,save the test drill pipe.It has four nozzles for discharging the debris.The drilling speed is twice of 2Wing bit and that makes it possess of much higher efficiency than the 2Wing bit and improve the efficiency of construction as well as reduce the miners’ labour intensity.PDC 3Wing shank drill bit fit for the terrane of f=9-12.
