When to Consider Gun Drilling

Gun Drilling is the process of choice when:

  • Hole depths are greater than 20x.
  • Holes would require reaming or honing to meet tolerances.  Gun drilling requires no reaming or honing.
  • With diameters of less than 20mm.  Larger diameters can be done more efficiently with BTA Drililng.

Sometimes even relatively shallow holes (by gun drill standards) benefit from gun drilling when straightness, diameter, and surface finish requirements are high.  The hole size, finish, and straightness of a gun drilled hole are all higher than with twist drilling, so eliminate a second reaming or honing op via gun drilling may save time.
