Left Hand Threading Tools - Designed for CNC and lathe applications.

Our left-hand threading tools are engineered for high precision and exceptional performance in demanding applications.

Designed with a 60° thread form, these tools are perfect for cutting UN, ISO, and NPT threads with ease and accuracy.

Available in uncoated and coated versions, the AlTiN+ coating significantly extends tool life, providing enhanced durability and resistance to wear, even under high-speed machining conditions.

Featuring a precision ground shank flat, these tools ensure proper tool orientation, reducing setup time and improving consistency.
