UNISIG USK series CNC knee-type deep hole drilling machines are designed for machining complex, very accurate workpieces. Diameter-to-depth ratios greater than 200:1 are possible due to a refined control of the drilling process.

  • Off Center Drilling
  • Specifically designed for routinely and successfully machining Inconel and other exotic materials.
  • Can be configured to be used with standard gundrill, and BTA/STS tooling or both with minimal changeover.
