What is PDC bit?

PDC BITS are drilling tools uses polycrystalline diamond compact (PDC) cutters to shear rock with a continuous scraping motion. These cutters are synthetic diamond disks about 8mm--13mm. Thick and about 13mm--16mm. In diameter. PDC bits are effective at drilling at soft to medium rock formation, as shale, limestone, dolomite and sandstone formations, especially when used in combination with oil-base muds. These bits are normally used at higher rotation speeds when drilling in certain formations, most typically homogeneous sedimentary rock formations.

PDC bits are designed for high speed drilling in shale, limestone, and sandstone formations.
These bits are a one piece solid steel body with no moving parts. The fixed-cutters shave away the rock, making it possible to operate with higher rotation speeds more efficiently in consolidated formations.

Champion New PDC bit

large circulation ports on the side of the bit instead of the bottom to reduce plugging in softer formations. bore through sandstone, limestone, granite, conglomerate, basalt, shale and any other hard substance that may impede us.
One Piece Steel Body PDC bits

These bits are recommended for drilling in soft to medium, sedimentary formations Mainly used for geological exploration,coal mining, water conservancy and hydropower, construction of road, railway, bridge and building.
PDC cutter

PCD or PDC cutter is a material composed by diamond and carbide matrix composite with high hardness, wear resistance characteristics, widely used in oil drilling, geological exploration, coal drilling bits and machining tools ,etc.
Anchor drill bits

Mainly used in drilling anchor nets support holes in coalfields, in mines for drilling holes for roof-bolts, providing a powerful guarantee for efficient roadway excavation.
