Our main market is China, USA, Russia, Canada, Australia currently.  We have established our US branch “Hai Ming Run Inc” as the service & marketing center for USA, Canada and Middle & South American customers in 2017.  

Our main product is PDC cutter for oil&gas drilling.

PDC cutter is Polycrystalline Diamond Compact Cutter, which consists of a polycrystalline diamond layer and a WC-Co hard alloy substrate, is made up by sintering diamond powder and WC-Co hard alloy substrate together under ultra-high pressure and temperature(about 1400-1500℃ and 60000-80000ATMS).   Please check out more details on the Introduction of PDC Cutters page. 

PDC cutters feature not only high hardness, wear resistance and thermal conductivity of diamond, but also feature high strength and impact resistance of tungsten carbide.  The WC-Co hard alloy substrate makes PDC welded on the bit body more easily.

1.  PDC drill bit is pressed into rock under the weight on bit when drilling hard formations, which makes the rock in contact with PDC cutters show plastic under ultra-high stress.

2.  In plastic (or the rock show plastic under ultra-high stress) formations, the inside parts of the rock ahead will be broken or flow plastically under the torque action of the PDC bit when PDC cutters cutting into the formations, finally the inside parts will disconnect from the rock matrix and form debris.

3.  In brittle formations, the rock is broken by shear force and strain as the rock will show brittle break under the weight on bit and the stress caused by the torque action, the ROP of the PDC bit will be high and the broken volume of the rock will be much more than the displacement volume after the PDC cutters cutting into formations in this situation.  

The appearance, impact resistance test, wear resistance test and thermal stability test is the main factor to evaluate the quality of the PDC cutter.

The actual drilling depth, ROP and wear grading of PDC cutters after lifting the bits is the main standard to evaluate the effect of PDC cutters.

Yes!  If you are our long-term cooperating customers and the needs are stable, reasonable stocks of the regular ordered models will be prepared for you to shorten the delivery time.

Yes!  Our oil level cutters UG series can be also used for mining drill bits which have showed very good performance in field drilling.  Our EQ series are specially designed for DTH drill bits which showed much better performance than tungsten carbide cutters.

Yes!  We have a brother mining PDC mining drill bits factory which manufactures mining PDC drill bits with HMR's self-manufactured PDC cutters, as we are oil & gas PDC cutters manufacturer, We are very confident that our Mining PDC Drill Bits with HMR's PDC cutters are much better than those PDC bits with mining level PDC cutters.
