Corner turning head — for R390-1806 indexable inserts, 90° cutting angle (Teknik Makina)

Corner turning head designed for 90° turning operations with R390-1806 indexable inserts, suitable for mounting on toolholders with a 22 mm shank.

• 90° cutting geometry for accurate corner turning
• Compatible with R390-1806 indexable inserts
• 22 mm shank diameter for secure mounting
• Torx clamping with M4x11 screw (T15 key)

Consistent geometry for precision turning

The 90° cutting angle guarantees repeatable corner profiles, which reduces the need for secondary machining and supports tight dimensional tolerances. The holder accepts R390-1806 indexable inserts, a widely used insert form that simplifies inventory and tool management. By pairing standard insert geometry with a stable tool head, machining cycles benefit from predictable forces and improved part-to-part uniformity.

Secure clamping and reduced setup time

A dedicated clamping arrangement using a Torx M4x11 screw actuated with a T15 key provides reliable seat retention and straightforward insert changes. The 22 mm shank ensures firm engagement with standard toolposts or toolholders, lowering vibration and improving surface finish. Faster insert swaps and consistent seating translate into higher machine uptime and fewer regrinds.

Compact design suited to diverse turning operations

With a 63 mm diameter and a total length of 45 mm, the compact form factor balances rigidity and accessibility in tight tool zones. The head incorporates 5 cutting edges, offering extended utility before indexation or replacement is required. At 0.49 kg, the component is lightweight enough for agile tool assemblies while remaining robust for industrial turning applications.

Built for workflow reliability and efficiency

Engineered as a component for indexable-turning systems, this tool head supports workflow optimisation by reducing fixture changes and set-up variability. Compatibility with inserts from established suppliers such as Sandvik helps streamline procurement and ensure proven cutting performance. The overall design contributes to predictable tool life and fewer interruptions on the shop floor.
