SIR S40T boring bar — right‑hand tool for 22 IR indexable inserts (Teknik Makina)

The SIR S40T boring bar is a right‑hand machining tool for IR indexable inserts, engineered for extended reach and robust shank stability.

• 40 mm shank for high rigidity
• 300 mm overall length for extended reach
• Compatible with 22 IR indexable inserts
• Secure Torx T15 clamping with M4x15 screws

Enhanced stability for consistent bore quality

The tool body delivers improved rigidity, primarily through its 40 mm shank and a 300 mm overall length that balances reach and stiffness for longer bores. With an external diameter of 46 mm and a mass of 2.84 kg, the design reduces vibration and run‑out, which directly supports repeatable hole tolerances and extended insert life. These mechanical advantages translate into fewer reworks and more predictable cycle times on production lines.

Fast, secure insert changes that cut setup time

Compatibility with 22 IR indexable inserts and the dedicated IR22 clamp ensure a reproducible cutting edge position after each change. The clamping system uses Torx T15 drive and M4x15 screws together with a U‑plate (TA063) and pass ring (BSP010) for reliable seating and torque control. This straightforward interface delivers quick insert replacement and consistent tool geometry, which eases tool presetter procedures and keeps machine downtime to a minimum.

Designed for workshop integration and efficient machining

Right‑hand cutting orientation and an ISO designation that matches common toolholder standards support rapid integration into existing setups. The combination of stable geometry and standardised fastening components helps maintain cutting parameters across shifts and operators, supporting lean production and predictable output. Supplied by Teknik Makina and distributed through Metav Werkzeuge, the component fits into a supply chain that emphasises dependable stock and quality control for industrial workshops.
