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 cutting edge that removes chips as it advances into iceland the metal tank building volume Hole drillingWell Owners Handbook - Minnesota Department of HealthA cable tool drilling machine uses a steel cable to raise and drop a heavy chisel-shaped bit, which breaks up sediment and rock into small pieces called cuttings. The cuttings are removed from the hole with a bailer a hollow tube or pipe with a valve on the bottom.
