The Carmex Thread Turning External Holder (Left-Hand) is a precision tooling solution for external threading on cylindrical workpieces. Built for reliability and rigidity, it supports left-hand thread operations with a secure, repeatable clamping system and a compatible insert lineup.

• Left-Hand configuration: Designed specifically for left-hand external threading to ensure correct cutting direction and thread form.
• 200 mm overall length (OAL): Provides extended reach for deep threads while maintaining tool rigidity and balance.
• 40 × 40 mm shank: Square shank for robust mounting and compatibility with standard tool-holders.
• 22EL insert compatibility: Delivers precise external thread profiles when used with Carmex 22EL inserts.
• U-Type holder design: Engineered to accommodate U-Type inserts for stable seating and accurate thread geometry.
• 1.5° helix angle: Optimizes chip evacuation and enhances cutting efficiency for consistent finishes.
• Screw clamp mechanism: Secure, repeatable grip to minimize tool deflection during threading passes.
• ER/EL insert compatibility: Flexible use with ER and EL insert families for various thread forms.
• External thread turning focus: Specifically engineered to deliver high-precision results in external threading operations.

With this Carmex holder, you gain dependable stability during heavy thread passes, delivering accurate thread pitch and smooth surface finishes. The combination of a 200 mm length and a 40×40 mm shank provides ample reach and solid support, while the 1.5° helix angle promotes efficient chip control and reduced cutting resistance. The screw-clamp design ensures consistent grip across multiple cycles, minimizing runout and tool chatter. Ideal for production environments requiring reliable external threading on fasteners, bushings, or threaded adapters, this holder pairs seamlessly with Carmex 22EL inserts for precise, repeatable results.
