High-performance internal threading tool holder SIL in left-hand design
The SIL series internal threading tool holder has been developed for demanding turning operations to produce internal threads. Configured as a left-hand tool and equipped with targeted cooling holes, this holder represents a well-thought-out solution for modern machining. Supplying the coolant directly to the cutting zone aids in controlled chip breaking and helps reduce heat generation during thread turning. Combined with a rigid screw clamping system, it achieves high positioning accuracy for 11/16/22 IL type indexable inserts.

Applications
This holder is an excellent choice for internal thread turning (left-hand application) across diverse industrial sectors. Whether in series production, tool and mold making, or machining complex workpiece contours, the SIL tool holder creates good conditions for reliable and consistent results in thread manufacturing.
Special features
The most prominent feature of this holder variant is the integrated cooling channel technology. It not only enables a constant temperature in the cutting zone but also promotes the continuous evacuation of chips from the bore. Furthermore, the solid screw clamping ensures a secure fit of the indexable insert even under demanding engagement conditions, thereby minimizing the risk of vibrations during the cutting process.
