Control Method of Drilling Depth in Blind Hole Drilling

Important tips for drilling:

  • The feeding amount should be small when the drilling starts, and the normal drilling can be achieved only after the cutting part of the twist drill enters the workpiece.
  • When drilling through holes to be drilled through the workpiece, the feed should be small in order to prevent the twist drill from breaking.
  • When drilling small holes or deep holes, the twist drill must always be withdrawn from the drill to remove chips, so as to prevent the twist drill from “biting” or breaking because of cutting blockage.
  • When drilling steel materials, cutting fluid must be poured sufficiently to cool the twist drill in order to prevent the twist drill from heating and annealing.
