Applications:

  1. High air pressure bit of 100-DHD3.5,The bit face designs is convex face,for high penetration rates in soft to medium-hard with low to medium air pressure,It is the most resistance to steel wash,and may reduce the load and wear on gauge buttons,but poor hole deviation control,but poor hole deviation control.

  2. The shape of the Carbide button shape gauge buttons and front buttons is domed/round button and parabolic-ballistic button respectively.The quantity both is 7 .The domed/round button are usually used as gauge buttons of DTH bits,suitable for very abrasive and very hard formations.The parabolic-ballistic button are usually used as gauge buttons and front buttons of DTH bits,suitable for medium abrasive and hard formations.The shank big length is 260mm,the total weight is 15.6kg.

 

Feature Advantage:

 

High air pressure bit speed and deep depth, it can be used for drilling more complex materials. It can choose higher cutting speed, can drill harder materials, multi-layer geometric cutting end edge, improve drainage performance and maintain small cutting resistance. In addition to the commonly used right angle handles, it is available in a variety of shank types, suitable for a variety of drilling rigs, drilling machines. A high-performance alloy blade for alloy drills is selected to effectively reduce the chipping and maintain good wear resistance.

 

Insufficient Cleaning Of The Well Bore And Excessive Abrasiveness Often Present Re-Drilling Problems That Can Cause Deformation Around The Venting Holes And Grooves.

 

Therefore, It Should Be Ground To Ensure That The Air Can Slam The Debris In The Drill. Severe Erosion Of The Bit Body And Energy Generated By The Piston Striking The Bit Will Cause The Alloy
