Chevron And Step Drag Bit Size 6 1/2


Drag bit and PDC drag drill bits 
Stratum conditions                                                                                                          
PDC drag  drill bits are  mainly used for drilling soft and medium -hard formation. Such as mud stone, limestone, shale, sandstone and granite etc.

Appication:                                                                                                                 

 PDC drag drill bits are used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water canservancy and hydropower, road construction, bridge and building. 

Operating condition :                                                                                                       PDC drag drill bits work under low drilling pressure, midium-low drive speed  ,big drainage .

Available size:                                                                                                                     50mm,  56mm,  60mm,  65mm,  75mm,  94mm,   98mm,  113mm,  120mm,  120.5mm,  124mm,  143mm,   149mm,  152mm,  173mm,   190.5mm, 203mm, 254mm

Wireline core bit :  A gauge, B guage, N gauge, H gauge , P gauge.  
After sales service  :                                                                                                           
If any of the following occur , we will responsible for replace . And we will afford the shipping cost of replace.
1. Thread can not fit customers' rod or barrels.
2.Matrix or PDC cutters falling not caused by drilling.
3. Size, Cutters , or other technical parameters are different from the requirement of customers.
4. working life obviously short caused by manufacture.

3.Main features                                                                                        

1. Cutting Structure of this type sealed and non-sealed tci tricone bits :

The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit.

2. Gauge Structure of this type tci tricone rock bits:

Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capability and bearing life.

3. Bearing Structure of this type tci tricone rock bits :

High precision roller bearing with two thrust faces. Ball locks the cone. Thrust faces hard face with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.
