Modular turning toolholders (THT) designed for a wide range of turning operations, from heavy roughing to high-quality finishing. The system uses interchangeable heads and standard ISO carbide inserts to offer flexibility and adaptability across multiple machines and applications.
OverviewThe THT modular toolholders are based on the patented HT polygonal tapered coupling that ensures a perfect fit and delivers outstanding torsional strength. The system combines a male component (with different machine attachments such as HSK, PSC, VDI, DIN, MAS, KM, etc.) with a female component (the tool body) available in many geometries to accommodate ISO carbide inserts (negative and positive). The modular approach enables composing many tool variants with a limited number of elements.
