Product Description

 Cutter structure of 

 In roller tooth surface, according to the single cone bit cone on tooth movement 

cutting way different characteristics, different regions of permanent decorate cone ball 

tooth contact area, alternate contact region decorate a cog, improve the efficiency

 of the teeth and broken rock;The most serious permanent tooth wear on the roller 

contact region, diamond composite tooth arrangement, strengthen tooth wear resistance.

Cone roof with protection of rock matrix in the plane of the tungsten carbide tooth, 

prevent rock basic wear and tear.

 

Gauge structure

Tooth claw part gauge set active gauge cone ball or wedge tooth, cutting bit has good 

protection function and the function of redressing.

Using radial sliding bearing, the adaptation of the tooth claw journal welding with wear-resisting gold, inner hole welding special alloys, enhance bearing abrasion resistance 

and resistance to bite and ability.Compared with the sanya cone bit, due to the bearing size, 

high reliability, drilling pressure ability.

Hydraulic design

Using small Angle nozzle flow design, enhance the claw back thickness, can

 effectively prevent the flow channel erosion.Optimization design of hydraulic 

structure can enhance the cleaning ability of the hydraulic system.Improve 

the rate of penetration.

Application

Applicable to the open window sidetracking, in deep well drilling and old well repair

spade drill bit of  Size,Type and Recommended Parameter
