Corner milling head for R390 17 indexable inserts — 40 mm, internal coolant (Teknik Makina)

The corner milling head for R390 17 indexable inserts is a compact cutting head built for precision external machining where small‑diameter tooling and through‑tool coolant are required.

• 40 mm cutting diameter
• Internal coolant supply
• Compatible with Sandvik R390 17 inserts
• Compact 45 mm overall length

Stable machining with small‑diameter tooling and defined geometry

The head offers a 40 mm diameter and a 90° cutting angle, delivering a reliable geometry for square shoulder cuts and light face‑turning operations. With 4 cutting edges, the tool distributes cutting forces across multiple inserts, reducing vibration and improving surface finish. The short overall length contributes to increased stiffness at the tool tip, which in practice means fewer reworks and higher process stability in repetitive production runs.

Internal coolant for cooler cutting and longer tool life

Integrated internal coolant directs cutting fluid close to the cutting zone, improving chip control and reducing thermal load on the inserts. This results in more consistent cutting conditions and extended insert life when using Sandvik R390 17 indexable inserts. For workshops seeking predictable performance, the coolant feature reduces the risk of built‑up edge and supports higher metal‑removal rates without compromising surface quality.

Practical assembly and serviceability to reduce downtime

Assembly uses Torx fastening with a Torx T15 key and supplied screw dimension M3.5x8.5, enabling quick insert changes and straightforward maintenance. The tool is held on a 16 mm connection (aufnahme 16 mm), keeping compatibility with compact holders and modular systems. The lightweight construction (approx. 0.276 kg) and compact 45 mm length allow rapid tool changes and reduced spindle load, helping to maintain production flow on medium‑duty lathes and milling centres.
