Modular Stability

A stable modular drilling platform accompanied by three insert geometry types to machine a variety of applications. 

TDMX was engineered with a secure pocket seat design to ensure maximum stability in challenging drilling applications like cross-hole, inclined entry/exit, and interrupted cuts.

Product Features:

  • X pocket seat design to increase stability in high-demanding applications
  • Insert diameter range from .629"-1.574" (16mm-40mm)
  • Margin lands on the entire body to ensure straightness and hole quality
  • Improved chip evacuation
  • Coolant channel exit behind the cutting edge
  • Flanged shank for higher rigidity
  • Polished flutes for improved chip evacuation
  • Tapered insert seat z-axis
  • Engineered grades for material-specific applications
  • Available to regrind 3x
  • Front clamping design easily removed from the body without disassembling the body from the holder to change the insert
