Blast hole drilling is used most frequently in the mineral exploration industry. The drill uses a pneumatic reciprocating piston-driven “hammer” to energetically drive a heavy drill bit into the rock. The drill bit is hollow, solid steel and has ~20 mm thick tungsten rods protruding from the steel matrix as “buttons”.
