Precision internal threading is made predictable with the Carmex Screw Clamp Threading Holder Through Coolant. Designed for professional machinists and job shops, it delivers reliable, high-quality internal threads with efficient coolant through the holder.

• Through-coolant bore: Provides coolant delivery through the holder to the insert, aiding chip evacuation and heat management for consistent thread quality.
• Internal threading support: Suitable for both right-hand (R) and left-hand (L) internal threading applications, increasing versatility across jobs.
• IR/IL insert compatibility: Engineered for use with IR (internal right-hand) inserts and compatible with IL (internal left-hand) inserts when paired with the appropriate setup.
• Screw clamp mounting: Secure, quick-clamp connection between the bar and insert to minimize tool displacement during machining.
• 200 mm overall length (OAL): Extended reach for deeper internal threading tasks and better access in challenging workpieces.
• 25 mm shank size: Standardized shank dimensions for compatibility with a wide range of tool posts and holders.
• Rugged construction: Built to withstand demanding threading operations, delivering stable performance and repeatable results.

This Carmex thread turning holder with through coolant is ideal for shops tackling precision internal threads in various metals. The combination of a coolant-through design, secure screw-clamp interface, and compatibility with IR/IL inserts helps you achieve cleaner threads, reduced heat, and longer insert life. With its substantial reach and robust build, it supports efficient production runs and tight tolerances, helping you complete deeper internal threads with confidence.
