Turning tools for internal turning and threading

Choose turning tools that match your machining task from the start: internal turning holders, external threading holders, internal threading holders and indexable inserts for common thread profiles. A well-matched holder and insert combination improves repeatability, surface finish and tool life, while making setup faster on manual and conventional lathes.

What to consider before buying

Start with the operation type. For internal turning, check shank size, holder geometry and insert compatibility. For threading, first decide whether you need external or internal thread cutting, then confirm insert size and profile.

It is also worth checking the workpiece material. The range includes threading inserts suited for steel, stainless steel, cast iron and hardened materials, helping you choose a more suitable cutting solution for your production or workshop use.

Holder and insert combinations

A good result depends on a compatible tool system. Internal turning holders such as SCLCR-type models are intended for precise internal machining, while NT-SER and NT-SIR holders are designed for external and internal threading. Matching 16ER and 16IR indexable inserts make it easier to build a practical setup for common threading applications.

If you already know your holder code or insert family, you can quickly narrow down the options by model designation. This is especially useful when replacing worn inserts or expanding an existing tooling setup.

For workshops, maintenance and small-series machining

These tools are suitable when you need dependable thread cutting and internal turning without unnecessary complexity. They fit well for workshop production, repair work and small-series machining where accurate dimensions and predictable insert changes matter.

Accessory availability also supports everyday use. In addition to holders, you can find compatible turning and threading inserts for replacements and routine stock-up purchases.

Delivery and buying support

Orders are shipped from Finland. For in-stock products, delivery is normally 2–4 business days depending on destination. If you are comparing holder sizes, insert profiles or threading options, our skilled staff can help you choose a suitable tool for your machine and application.
