Polycrystalline Diamond Compact Bits

Main components of polycrystalline diamond compact bits are steel body and polycrystalline diamond composite sheet. Bit has firm structured, without moving parts and wearing parts, which is help to prevent drilling accidents.

Features

1. Broken rock in shear way. PDC drill bits feature high rock breaking efficiency in medium to hard formation stratum.
2. Polycrystalline diamond compact bits have diverse shape cutting tooth, reasonable structure, and high speed machinery rotate.
3. Low bit pressure is required and the drill string load is little.
4. Good thermal stability is easy to adapting to high rotate speed.
5. Bit has firm structured, without moving parts and wearing parts, which is help to prevent drilling accidents.
