The common factors for choosing trepanning are a long design, through bore, and within size ranges of 4.1″ to 15.75″.

Trepanning can be utilized in:

  • Machinery and Heavy Equipment
  • Manufacturing and Rebuild
  • Oil and Gas
  • Aerospace and Defense
  • Metals Production and Distribution
  • Forging

Can be utilized when holes may be required in:

  • Finished Parts for Weight Reduction
  • Clearance
  • Fluid Flow
  • Working Cavities
