The Carmex Vertical Slim Throat Thread Turning Holder (External, Left Hand) is a precision tool designed for external threading in tight, hard-to-reach spaces. It’s the right choice for machinists who need reliable performance from a compact, rigid holder.

• Throat Design: Vertical Slim Throat optimizes access in restricted areas during external threading.
• Handedness: Left-hand orientation for proper cutting direction in standard threading operations.
• Overall Length: 150 mm (OAL) to reach deep into assemblies while maintaining control.
• Shank Size: 25 x 25 mm square shank for secure seating in toolposts and holders.
• Insert Compatibility: Accepts 16VEL inserts for external thread profiles.
• Construction: Precision‑machined from high‑quality materials to deliver rigidity and long service life.

Designed to tackle external threading tasks in cramped work envelopes—think small-diameter fasteners, instrument housings, and tight automotive components. The slim throat reduces clearance requirements without compromising alignment, while the 150 mm reach provides the leverage you need for accurate thread formation. Paired with 16VEL inserts, this holder helps you achieve consistent thread tolerances, minimize rework, and keep production moving in space‑constrained setups.
