Button Bit Hole Drilling | Rock Mining Heads

Rock Head Drills
You will achieve consistent production of holes in steel rock drill heads (50 - 60 HRC) through using our precision drills -
engineered for high positional accuracy, stability,
and hole size.

Ensuring optimum interference fit between the carbide button/bit and the rock drill head is one method of minimising significant costs associated with premature button/bit failure. Cajero drills afford you the confidence that at least one potential obstacle is overcome.
