High reliability, stability, and efficiency

m_306_m_01

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
