Trepan Tools

Trepanning cuts only the circumference of the hole leaving a center core for other uses. It is faster and more economical to cut the circumference of deep holes rather than converting all of the material in a hole into chips.

Trepanning Using Muskegon Tools

Trepanning is the fastest and most economical method of producing holes from the solid.
  1. Start with the properly-engineered tools
  2. Utilize the correct geometry
  3. Use the proper starting technique for the work piece
  4. Employ feeds and speeds that assure disposable chip configuration
  5. Use a recommended coolant at the correct volume and pressure
  6. Contain the coolant for optimum chip disposal
  7. Arrange for removal and disposal of cores
