Carmex Thread Turning Holder Standard - Internal - Right Hand - 350mm OAL - 33UIR Insert - 50 Shank Size

The Carmex Thread Turning Holder Standard for Internal threading is a purpose-built tool holder designed for precise internal threads in machining and manufacturing. Built for right-hand internal threading, it offers a 350 mm OAL and 50 Shank Size for deep-bore reach and stable guidance, with secure compatibility for U-Type inserts.

• Handedness: Right-hand internal threading holder designed for clockwise internal threads.
• Overall Length (OAL): 350 mm, providing extended reach into deep bores for internal threading operations.
• Shank Size: 50, ensuring robust support and compatibility with standard tool changers.
• Insert Compatibility: 33UIR insert compatibility for reliable, repeatable performance in precision threading.
• Holder Type: U-Type holder engineered to securely fit U-Type inserts for precise alignment and stability.
• Helix Angle: 1.5° helix angle optimizes chip evacuation and reduces cutting forces for smoother threading.
• Clamping System: Screw clamp design delivers secure seating and minimizes tool runout during operation.

With its dedicated internal-threading capability, this holder helps you achieve cleaner, more accurate internal threads with fewer passes. The long reach reduces the need for multiple setups, while the 1.5° helix improves chip management and lowers wear on both tool and workpiece. The combination of a secure screw clamp and U-Type insert compatibility provides dependable centering and repeatable results across a range of internal threading tasks, making it a practical choice for precision machining, maintenance, and production environments.
