Value:
Carbide Drill Bushings are frequently utilized in oil exploration or oilfield boring tools. These devices have a typical demand, which is to run at high speed in severe atmospheres for a long period of time. The drill bit utilized throughout exploration has a greater expense contrasted to the drill bit. For that reason, in order to decrease the rubbing between the drill bit and the outdoors, a Carbide Bushing Type is typically positioned on the exterior.
Highlights:
1. Outstanding durability and hardness of all hard alloy products
2. Strict quality inspections of each process
3. Exceeding stress tolerance and compressive capacity
4. Personalized service is provided
Advantages:
The outstanding solidity of Drill Guide Bushings enable them to preserve their initial form even after being pressed by below-ground rocks, efficiently safeguarding the drill bit and making the whole work procedure smoother.
