  • What is Gun Drilling?

    Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes in metal at high depth-to-diameter ratios. Gun drilling is effective in diameters from 1 – 50 mm [0.04 – 2.00 in]. A gundrill tool differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective
