Easy-to-index milling cutters for superior surface quality

High reliability, stability, and efficiency

Applications & Features

Applications

Face milling

Features

Excellent surface quality

  • No axial/radial run-out adjustments needed.
  • The insert pockets are designed so that the finishing insert always performs the finishing, providing consistent surface roughness.
  • Light cutting geometry with wiper edge incorporating a great circular arc.

First choice

  • Provides superior surface quality

Light cutting

  • Generates light cutting action with excellent surface finishing thanks to the same wiper geometry as the LNCQ0906N-100L.

For super light cutting / Finishing close to the shoulders

  • Reduced radial force
  • Allows minimum interference with the shoulders when machining into the Cutting force work corners

Optimizing the insert combinations for workpieces with thin walls or shoulders
