1. high efficiency and longer life expectancy. 2.It is becoming main products in the oil fields in the domestic and abroad.

"JSRNC" series is our new generation PDC cutter. It is our most advanced PDC  cutter at present. Developed in 2004 and has been made several important technical improvement.

1. Diamond thickness is increased to 2.0mm (JSRTC: 1.7mm),2. The impact strength is higher than the old series. 3. Wear resistance is a bit higher than old series. 4. Heat resistance is improved to 750 centigrade degrees while previous RTC is 700. New Technology: 1. The diamond powder is selected in a higher degree. 2. Use a new type of tungsten carbide that different from JSRTC cutters, which improved the strength character of bonding.3. The claws of the interface are changed to be net-grooves-shaped which formed by 20 straight vertical grooves, and the depth of the grooves are shallower.4. Improved the interior structure of the sintering cell that makes the pressure and temperature to be more uniform. It is very important for the PDC sintering.5. Use new super heat-resistant metal, to avoid being contaminative during sintering. 6. Amended the sintering processing, and improved the bonding strength of the diamond-diamond key among the diamond layer.7. Increase the content of diamond, and increase the thickness of diamond layer up to 2.0mm.

 In past year, JSRNC cutter is very widely used in China and other countries. It accepted by most customers and successfully substituted the old JSRTC cutter in the market.
