The SUMOTURN line includes external and internal tools, as well as large sized inserts for roughing and heavy duty applications.. Rough and heavy duty turning applications feature relatively large depths of cut, high feed rates and rough, non-uniform surfaces to be machined. These applications require both tough carbide grades and specifically designed chipformers.
The tools are equipped with a lever lock clamping system, which is recommended for large depths of cut and interrupted cut applications.
The SUMOTURN inserts are coated with ISCAR’s innovative SUMOTEC grades.
In order to assist customers in selecting the correct grade for their applications, ISCAR developed new coating processes for the SUMOTEC grades featuring different colors for easy identification. (The older SUMOTEC grades featured the same gold color.)
This coating technology improves insert life by 5 to 12% compared to the previous coatings.

Based on accumulated experience with the ISO TURN line, ISCAR designed a range of chipformers which, together with the most advanced SUMOTEC grades, provide higher productivity, tool life and performance reliability.
The inserts carry systematic designations in order to facilitate insert selection by the end user.
