Bringing drill bit re-sharpening to the rock face

摘要

The most important factor contributing to premature drill bit failure and poor drilling performance is 'overdrilling' or operating beyond the reconditioning point. Failure to regrind in time can prove costly. Regular checks are important to maintain maximum penetration rates and to avoid overheating the bit, as this can destroy its metallurgical properties. Re-profiling the carbide button and removing excess steel is important in order to optimize drill bit service life, enhance the performance of the entire drilling operation and keep down the drilling and grinding costs.
