Boring bar S10J STIR — STI for IR/ER indexable inserts, right-hand, by Teknik Makina

Boring bar S10J STIR is a right-hand, STI-compatible boring bar designed for use with IR/ER indexable inserts in confined machining setups.

• Right-hand STI holder for IR/ER inserts
• 10 mm shank diameter for compact installations
• 110 mm overall length for restricted bores
• Low weight 0.079 kg for easier handling

Precision where space and repeatability matter

The S10J STIR boring solution is engineered for consistent, repeatable performance in constrained environments. Thanks to its STI interface and compatibility with IR/ER indexable inserts, the tool secures inserts with defined geometry and repeatability, reducing set-up time and positional error. This results in improved tolerance control when finishing bores or performing light internal turning operations. The measured design supports stable cutting conditions, which helps to reduce vibration and extend the life of both the insert and the holder.

Compact dimensions that increase rigidity and control

With a 10 mm shank and 110 mm overall length, this boring bar minimises overhang and improves stiffness at the cut, delivering better surface quality in tight bores. The tool’s 12 mm diameter and 20 mm cutting height are optimised to balance accessibility with mechanical stability. The low mass of 0.079 kg makes handling and inventory management easier while the compact form reduces centrifugal forces at higher spindle speeds. For production environments where space and repeatability are critical, the compact geometry translates directly into fewer rejects and more consistent cycle times.

Secure clamping and easy system integration

Designed for the STI holding system and compatible with the IR11 clamping variant, the bar integrates smoothly into modular tooling setups. The ISO designation S10J STIR provides a standard reference for toolholders and adapters, simplifying procurement and fixture planning. Installation is straightforward: the profile aligns with established STI interfaces and the right-hand cutting orientation matches common machining sequences. Combined with Metav Werkzeuge’s supply chain and technical advice, the component can be specified into process plans with confidence, reducing downtime and ensuring rapid fitment.
