What is the difference of the new cutter? Why advanced?

 Improvement:
1.  Diamond  thickness  is  increased  to  2.0mm  (S-RTC:  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  S-RTC  is  700. 

The  advantages  of  the  new  S-RNC  cutter  is  based  on  the  improvement  of  the  technology,  which  has  completely  updated  in  several  factors:  

 New Technology:
1.  The  diamond  powder  is  selected  in  a  higher  degree.  
2.  Use  a  new  type  of  tungsten  carbide  that  different  from  S-RTC  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.

 The   result   of   plenty  of  tests  and   the   performance   in   customers'   practical  drilling  in  the  oil    fields    shown   that   the  performance  of   "S-RNC"   in  heat  resistance  and  impact  resistance  are  improved  evidently,  and  quite  similar  to  the  cutters  made   by   the   best   world-class   manufactures.  In   past   year,   S-RNC   cutter   is   very   widely   used  in   China   and  other   countries.   It   accepted   by   most   customers   and   successfully   substituted   the   old   S-RTC   cutter   in   the   market.
