180° Flat-Bottom Drills • Through Coolant

  • FBG is material-specific for best performance in non-ferrous materials.
  • Creates a true flat-bottom hole from O.D. to center.
  • Four-margin land design improves hole straightness and roundness and provides good alignment, even when drilling cross holes.
  • Can run into cored holes.

Application-specific SC drills that combine two operations in one:

  1. Eliminate the 180° end mill in flat-bottom drilling or when preparing an inclined or curved surface for drilling.
  2. After full cylindrical engagement, the drill runs at normal solid carbide drilling parameters.
