Clamping holders & boring bars for thread turning | Internal & external

A thread is only as good as the tool that forms it. Since threads often serve as safety-critical connections, dimensional accuracy and a clean flank surface are non-negotiable. Our tool holders (for external threads) and boring bars (for internal threads) form the indispensable foundation for this demanding process. Manufactured from specially heat-treated steel and refined through advanced hardening processes, these tool holders provide the maximum rigidity required to withstand the high radial cutting forces involved in thread turning.

Vibrations are the enemy of every thread flank. Our solid holders and vibration-damped boring bars effectively eliminate chatter marks and ensure absolute profile accuracy – whether you are producing in series on CNC machines or manufacturing individual parts on a conventional lathe. The precise insert seat design guarantees that the indexable insert remains accurately positioned even under load. From delicate precision engineering to heavy-duty machining: equip your machine with holders that bring precision to every pitch.

Invest in process reliability and order your thread turning tool holders for internal and external machining now.
