The Carmex Thread Turning Holder Through Coolant is a precision internal threading tool designed for reliable, repeatable internal threads in a variety of workpieces. Built for through-coolant operation and secure insert mounting, it supports both right- and left-hand threading setups when paired with the appropriate inserts.

• Through-Coolant Bore: Integrated coolant passage helps evacuate chips and keep insert temperatures under control for steadier cuts and longer insert life.
• Internal Threading Focus: Specifically engineered for internal threading operations, delivering accurate thread forms and consistent results.
• Insert Compatibility: Optimized for IR (internal right-hand) and IL (internal left-hand) inserts, enabling flexible RH/LH threading configurations.
• Screw-Clamp Connection: Robust screw-clamp mechanism secures the insert to the holder, minimizing displacement and maintaining precise alignment during machining.
• Right-Hand Orientation: Tailored for right-hand threading applications while supporting left-hand setups when using the corresponding inserts.
• 125 mm Overall Length (OAL): Sufficient reach for deeper internal features without compromising rigidity or control.
• 16 mm Shank Size: Compatible with standard tool holders, promoting stable, balanced performance in typical CNC setups.

Designed for production environments that demand precise internal threads and dependable tool retention, this Carmex holder helps reduce rework and improve thread quality. The combination of a through-coolant feature, secure screw-clamp insert hold, and compatibility with IR/IL inserts makes it a versatile choice for automotive, hydraulic, and aerospace components, as well as general precision machining tasks. For best results, pair with the appropriate IR/IL insert, ensure proper coolant flow, and follow manufacturer guidance for seating and clamping torque to maintain repeatable accuracy across jobs.
