Clamp holder SER 4040 – right‑hand external threading, 40 x 40 mm – Teknik Makina

A heavy‑duty clamp holder engineered for right‑hand external thread turning and compatible with 27 ER indexable inserts in professional machine shops.

• Robust 40 x 40 mm clamping body
• 40 mm cutting height for deep threads
• Secure M5x18 Torx fastening
• Compatible with 27 ER indexable inserts

Stable geometry for repeatable thread quality

The primary advantage of this toolholder is its precise clamping geometry. The 40 x 40 mm cross section and 40 mm cutting height provide a rigid interface that reduces vibration during threading cycles, which in turn improves surface finish and dimensional repeatability. Mass distribution and the unit’s 2.589 kg weight contribute to stability on the carriage, so thread forms are produced consistently even under interrupted cuts. The ISO designation SER 4040 identifies the shank profile for straightforward integration into standard toolposts.

Quick assembly and secure fixing to reduce downtime

Designed for efficient workflows, the holder accepts 27 ER indexable inserts and mounts on the R27‑ER27 boring bar designation, enabling rapid insert changes without extensive reset procedures. Fixing is by an M5x18 Torx screw tightened with a T20 key, a combination that gives positive clamping force while remaining serviceable on the shop floor. The included U plate reference TA064 ensures compatibility with common mounting plates. Together, these features reduce set‑up time and make the toolholder suitable for batch production or mixed‑series turning tasks.

Practical applications and operational benefits

Optimised for right‑hand external threading, this holder is intended for industrial turning centres and manual lathes where reliable thread cutting is required. The robust construction supports operations in toolrooms and production lines that demand repetitive accuracy rather than one‑off setups. The overall length of 200 mm gives an accessible reach without compromising rigidity, and the toolholder is specified for right‑hand cutting direction. For purchasers, the clear technical alignment with 27 ER inserts simplifies stocking decisions and streamlines tool change procedures.

Durability, compatibility and supply confidence

Manufactured by Teknik Cutting Tools and distributed through Metav’s European channel, the holder benefits from tested manufacturing processes and logistical support from Emmerich. The combination of standardised ISO shank, proven fastening elements and common insert compatibility minimises the risk of mismatched components. For operations aiming to improve first‑pass yield on threaded parts, the assembly represents a pragmatic, high‑performance choice that balances ease of use with industrial robustness.
