5xD Blackmamba Coolant Thru Drill, Drill Bit Size: 13.60 Mm

  Rather than drilling out the metal with a solid drill, Drillco cutters remove only the periphery of the hole, ejecting a slug at the end of the cut.Broach cutting using Drillco cutters means you can produce large diameter holes efficiently and quickly with less energy, faster penetration and less thrust..

Because of the inaccessibility or the extreme depth of a hole, it is found that even long series drills are not long enough.  The drilling of such holes generally requires the use of an Extra Length Drill..
