PDC cutters (Polycrystalline Diamond Composite) is consist of polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high temperature and pressure, the PDC cutter like 1308,1313 etc, PDC cutters are widely used in petroleum/oil field PDC bit, geological PDC exploration bits, gas exploration bits, PDC coal mining drill bits, oilfield drilling bits,currently, we developed new type of PDC cutters, the length of the cutter is 32mm, with a round radius of the tungsten carbide substrate of the PDC cutter.

PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.

Microstructure with complete C-C bond combination is characterized between the grains of diamond in polycrystalline diamond layer, which allows the high strength, high hardness and high wearing property of diamond layer as well as good self-sharpening property. New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks.

PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller cone bit or plowing and grinding of rocks by diamond impregnated bit.

the serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the two layers and allows more impact resistance of the whole PDC.

PDC-F (Flat cutter)
Spec:	0505 0808 0810 1008
Info:	the flat surface combines small specification size to be applicable to PCD auger to protect through area, with other drill not into the use, such as measure tool etc..

PDC-C (claw cutter)
Spec:	1308 1313 1613 1913 1916 1919
Info:	the teeth of a saw type combines. the increment concludes to match of the strength reduced interface in response to the dint. the usage takes directive. the medium etc. Anti- impact uses thicker diamond grain, the increment drills into the efficiency. Diamond layer 1.2 －2.0 MM can be provided as choice. Apply softer geologic strata.

PDC-S(streng the ned daw)
Spec:	1308 ．1313 ．1613 ．1913 ．1916 ．1919
Info:	the wreath form combines central part to take several teeth of a saw type to have directive but not easy confirmation to have stronger anti- sex to pound at function to bear to whet sex senior high school etc. the diamond grain apply medium soft bear to whet geologic strata, diamond layer 1.5 － 2.5 MM can be provided as choice.

PDC-G (great strengthened claw)
Spec:	1308． 1313． 1613 ．1913 ．1916
Info:	Three layers of complicated structure, biggest of reduce internal help dint, take to drill into the direction, high anti- impact, be applicable to more complicated geologic strata, medium thick diamond grain, have good of comprehensive function, diamond layer 2.0 － 3.0 MM can be provided as choice.

PDC-(C S C)-R
Spec:	1320, 1925, 1929
Info:	Can choose a variety to combine a way, empress the department present a semicircle type, being applicable to just body auger.
