We supply new and secondhand and scrap drill bits, PDC bits, TCI bits, tricone bits, rock bits, PDC diamond bits, cone bits,etc.

 

 

1.Working priciples and applications:
Roller bit is widely used in drilling rock formation ,oil drilling ,geological drilling ,etc.It is divided into

 

steel teeth and inserted teeth as the difference of the cutting material .The cutting tooth touch the

 

well bottom in turn ,the rock fragmentation torque is small,the touching area of the cutting tooth

 

and well bottom is small,the beta ratio is high , it is easy to enter the layer; the total working blade

 

length is big ,thus reduce the attrition relatively . Roller bit is adapt many soft and hard layers .

 

2.Features and advantages:

 
1) Powdered metal matrix body for longer service life.
 
2) Advanced geometric design for faster penetration.
 
3) Added cutters for maximum performance.
 
4) TSP gauge protection.
 
5) Large junk slots for better hole cleaning.
 
6) Oil field technology for deep hole drilling.
