When working in soft rock formations and changing the drill bit in the middle, it is necessary to strictly check whether the alloy teeth on the palm back of the old drill bit and the roller cone fall off custom Ship Auger Bit Manufacturers to the bottom of the hole. After the teeth are crushed and eaten into the rock, they also slip and shear the rock at the same time.

During normal piercing operations, the main air path of the air compressor should not have serious air leakage to ensure sufficient air volume and air pressure to extend the service life of the drill bit. When it is rolling at the bottom of the well, the teeth on it will sequentially impact and press into the formation. The drill bit should be reasonably stored on the drill to prevent dust and other debris from entering the drill bit.

When drilling rigs, follow the principle of matching the three elements of drilling (wind pressure, axial pressure, and speed) with the parameters recommended by the drill bit sample. When the drill bit is in the hole and the air compressor suddenly stops working, the slag can easily enter the drill bit. When the drilling tool is in the hole, it is strictly forbidden to reverse to prevent the drill bit from falling into the well. When the drilling rig is stopped, the drilling tool cannot be parked in the hole with water to prevent slag and water from flowing back into the bearing and damaging the drill bit.

When there are cracks in the rock or rock cracks caused by blasting and the work in the mined-out area, the axial pressure and speed should be reduced to prevent the teeth from breaking. In the process of transportation, it is strictly prohibited to knock the cones and threads.

The remaining rocks in between broke the rocks at the bottom of the well and the well bore was extended. It is strictly forbidden to use curved drill pipes to avoid uneven force on the three palms of the drill bit and accelerate the damage of the drill bit. After the teeth are crushed and eaten into the rock, they also slip and shear the rock at the same time
