In today’s competitive environment, miners are demanding improved processes and equipment to add value to their mining operations. To increase efficiency and lower drilling costs, blasthole rigs are expected to deliver more and more energy to the drill bit. As a result, drill bits must be carefully designed and manufactured to not compromise the productivity and efficiency of increasingly complex and expensive drilling systems. Bits have become an even more critical and vital component in this process.
Tricone bits – Verified in the lab, for superior performance in the field.
Our tricone bits product line promises the highest performance, reliability, and availability. This effectively results in a lower drilling cost. With sealed bearing product line, takes the guess work out of drilling. Our bits are designed to increase bit life even further where the application presents restrictions to drilling.
1. Advanced technology
HKX series is a product of our extensive field experience combined with sophisticated research and development, including advanced simulation technology.
2. Balanced cutting structure
Cutting structures (the placement of inserts) and bearing geometry have been optimized to distribute load more uniformly over the bearings. The result is a smoother and more balanced cutting structure, allowing sustained penetration rates over longer periods of time, with reduced risk of bearing failure. As an added bonus, full body armour minimises wear on both bit body and shirt tail.
3. Lower total drilling costs
Our bits are designed with streamlined lug allowing the ejection of larger pieces or rock. Ultimately, you can now look forward to faster penetration rates, longer bit life, and significantly lower total drilling cost. It now takes less time to get the job done!
