Carmex Thread Turning Holder Through Coolant - Internal - Left Hand - 250mm OAL - 16IL Insert - 32 Shank Size

The Carmex Thread Turning Holder Through Coolant, Internal Left Hand, is a precision tool holder engineered for internal threading with through-coolant efficiency. Designed for deep bore applications, it accepts 16IL inserts and provides dependable left-hand internal threading performance in demanding machining environments.

• Through-coolant bore: Delivers coolant directly to the cutting edge for improved chip evacuation and temperature control during internal threading.
• Internal left-hand threading: Optimized for left-hand internal threads with IL inserts, delivering consistent, accurate results.
• 250 mm overall length (OAL): Long reach to access deep or hard-to-reach internal threads while maintaining rigidity.
• 32 mm shank size: Robust shank compatibility for reliable fit in standard tool changers and holders.
• 16IL insert compatibility: Designed to pair with internal left-hand IL inserts for secure, precise cutting edges.
• Screw clamp connection: Strong clamping action minimizes insert movement and enhances tool life and reliability.

This holder delivers cleaner, more uniform internal threads by combining a secure screw-clamp interface with efficient through-coolant delivery. The result is improved surface finish, reduced insert wear, and consistent tolerances across production runs. It’s an ideal choice for deep internal threading tasks in engine components, gear housings, hydraulic blocks, and other assemblies where reliable left-hand internal threads are essential. Choose this Carmex holder when you need precise, repeatable results from a rugged, purpose-built threading solution.
