Clamping toolholder D268TM — for external threading, left‑hand, compatible with 16 IR inserts (Teknik Makina)

Clamping toolholder D268TM for left‑hand external threading, designed for stable, repeatable performance on turning centres and lathes

• Left‑hand cutting for external threading
• Compatible with 16 IR indexable inserts
• ISO designation AL 2020 compatibility
• 125 mm overall length, compact footprint

Faster, more reliable external thread turning

The left‑hand geometry of this clamping toolholder enables efficient production of external threads where a left‑hand cut direction is required. Thanks to a rigid clamping concept and compact dimensions, operators benefit from reduced vibration and improved surface finish. With the toolbody engineered for stable force transmission, setup times are shortened and the likelihood of rework is lowered, delivering tangible productivity gains on batch and single‑piece work alike.

Compatible interface for indexable inserts and shanks

Designed to accept 16 IR indexable inserts, the holder matches common insert formats to simplify tooling logistics. The body also corresponds with the K16/IR16 shank designation, enabling straightforward integration into existing toolsets. This compatibility reduces the need for special adapters and makes the holder suitable for a broad range of turning centres and post‑holders, helping to standardise tooling across a workshop.

Compact dimensions that support workshop ergonomics

With an overall length of 125 mm, a head and body width of 20 mm and a cutting height of 25 mm, the clamping toolholder offers a compact footprint while preserving cutting stability. Its balanced mass (approx. 0.416 kg) eases handling during set‑up and minimises additional load on the turret. These dimensional values make the holder practical for confined setups and for machines with limited overhang, ensuring predictable chip control and consistent thread form.

Practical benefits for production and maintenance

The ISO designation AL 2020 indicates a standardised interface that simplifies replacement and spare management. Designed for indexable inserts, the holder supports quick insert changes that reduce machine downtime and increase effective cutting time. Where repeatability and short cycle times are priorities, the combination of standard insert sizes, compact geometry and secure clamping helps deliver measurable process stability and lower total machining costs.
