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.
