Drilling Tools#drill machine construction#
The saying "A skilled craftsman must first sharpen his tools" and "Sharpening the axe doesn't delay the work" both highlight the importance of drill bits.
1. Function of Drilling Tools: The torque and pressure output by the drilling rig act on the drill teeth to cut and break up the geological formation, and collect the drilled material in the drill bit using different methods to bring it out of the borehole.
2. Types of Drilling Tools: Double-bottom sand scoop (conventional geology), Double-bottom rock drilling (medium difficulty geology), Spiral drill (dry hole, jointed rock), Rock drill bit (high difficulty geology), Pressure wheel drill bit, Pressure wheel drill (extremely high difficulty geology)#drill machine construction#
Drill Teeth
1. Function of Drill Teeth: To concentrate the output torque and pressure of the drilling rig, cutting or breaking the geological formation through the sharp cutting edges at the front of the teeth.
2. Types of Drill Teeth: Bucket Teeth: (Linear cutter) Cuts the geological formation through the cutting edge at the front of the bucket teeth (suitable for conventional geology); Cutting Teeth: (Point cutter) Breaks the geological formation through the alloy head at the front of the cutting teeth (suitable for high-strength geology).
3. Selection of Drill Teeth: Select drill teeth according to the geological type. For pebble layers (Bauer teeth: wear-resistant, high strength), for conventional geology (bucket teeth: cutting), for hard geology (cutting teeth: breaking).#drill machine construction#
