3.5.3 MTSRH – Endmill and Shell Mill for Helical Indexable Inserts
THREAD MILLING Endmills and shell mills for helical indexable inserts (27-38 mm) are the ultimate solution for

very fast and efficient thread milling. The helical inserts engage with the workpiece smoothly
and, when compared with straight, negative axial tools, exert lower cutting forces and
reduce vibration.
MTSRH tools are available with internal coolant channels directed to the cutting area.
These tools can be used for production of internal and external threading.
The tools carry up to 9 inserts depending on the tool diameter, which enables machining at
very high feeds and produces a high-quality surface finish.

A simple and very convenient screw clamping mechanism makes insert indexing accurate
and user-friendly. By using these thread milling tools, thread production time can be
very short.
