Features:1.Thediamond powder is selected in a higher degree. 2. Use a new type of tungsten carbide that different from previous cutters, it improved the strength character of bonding.3. The claws of the interface are changed to be net-grooves-shaped which formed by 10-20 straight vertical grooves, and the depth of the grooves are shallower.4. Improved the interior structure of the sintering 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 contaminativeduringsintering.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 diamondlayer up to 1.5-2.0mm.The result ofplenty of tests and the performanceincustomers' practical drilling in theoil fields shown that the performance inheat resistance and impact resistance are improved evidently, and quite similarto the cutters made by thebest world-class manufactures.
