Clamping Holder D258TM — right‑hand holder for external threading by Teknik Makina

A clamping holder D258TM designed for right‑hand external threading operations, compatible with 16 ER indexable inserts and engineered for stable clamping in lathe tool posts and turret stations

• Right‑hand cutting direction
• Compatible with 16 ER indexable inserts
• 20 mm cutting head width and 20 mm height
• 125 mm overall length

Accurate thread turning with proven indexable insert compatibility

The D258TM is specified for external threading and accepts 16 ER indexable inserts, allowing manufacturers to rely on standard insert geometries for consistent chip control and repeatable results. The holder’s 20 mm head width and 25 mm cutting height provide a secure seat for the insert, which reduces vibration and maintains thread form across batch runs. This leads to measurable improvements in process stability and fewer rejects when producing external threads on turned components.

Compact design for fast set‑up and seamless workshop integration

With an overall length of 125 mm and a mass of 0.416 kg, the tool holder is compact enough for tight tool layouts while offering sufficient reach for typical external threading tasks. The shank designation K16‑ER16 aligns the holder with common toolpost configurations, helping to limit inventory complexity and accelerate changeovers between operations. The ISO designation AL 2020 indicates a standardised geometry that supports predictable positioning and easier replacement scheduling.

Practical advantages that reduce downtime and support productivity

Engineered with right‑hand cutting in mind, the clamping system secures the insert firmly for high repeatability during thread cutting. The combination of standard insert compatibility and a straightforward clamp design shortens maintenance intervals and simplifies insert indexing. For production environments, this translates into lower machine idle time and clearer planning for tool life, wear allowances and reconditioning cycles — practical benefits for both single‑part jobs and serial production.
