Directional drilling pilot is a frequently used power-driven drilling pilot in well drilling , long-term and high speed drilling of the horizontal boring, sandstone drilling etc .
Plate-type Guide Drill Bits:
The drilling pilot is composed of drilling pilot plate and drilling tools. The guide plate is designed with alloy steel in its front part, with various steering blades optional. It can be selected according to different geology to improve construction efficiency.
Type : Direct connection & Octagonal connection.
Two optional types of pilot with sonde housing : side-load and back-load type.
Features of side-load drilling pilot : Easy dismantle time and effort saving .
Features of back-load drilling pilot : Waterproof greater torque, compression resistance, less likely for bending, but time consuming.
Eagle Claw Type Drill Bits:
Eagle claw bit is designed for medium hard soil conditions designed with interchangeable cutter. The edge of the drill bit is designed with wearable strip, greatly improving life time of the drill bit.
