S16Q STIL Boring Bar (STI for IR/ER indexable inserts) – left‑hand, ER16 shank by Teknik Makina

The S16Q STIL is a left‑hand boring bar designed for internal turning with IR/ER indexable inserts, offering a compact shank and ER16 clamping for precision machining in confined spaces

• Left‑hand cutting direction
• ER16 clamping system
• 180 mm overall length
• Compatible with 16 ER inserts

Stable performance for internal turning and indexable inserts

The holder delivers consistent stability when machining internal features thanks to its robust shank design and predictable geometry. With a 16 mm shank diameter and a 20 mm outer diameter, the toolholder minimises vibration in medium‑duty turning tasks and keeps insert engagement steady. Using indexable inserts reduces downtime for regrinding and cuts tooling costs: the STI concept for IR/ER indexable inserts allows fast insert changes while maintaining repeatable seating and cutting angles. For shops moving from solid tools to modular systems, this design provides a tangible increase in process reliability and a lower total cost of ownership.

Secure clamping and straightforward compatibility

Designed around the ER16 clamping system, the bar ensures a firm connection to standard collets and holders found in many CNC lathes and turning centres. ER16 compatibility means familiar workshop equipment can be used without additional adapters, simplifying tool inventory and changeover. The nominal cutting height of 40 mm gives enough clearance for common insert geometries, while the left‑hand orientation suits operations where tool approach and spindle direction require inverse cutting. This combination supports efficient toolset standardisation across a production cell.

Practical dimensions for tight bores and compact setups

With an overall length of 180 mm and a weight of 0.286 kg, the bar is tailored for confined setups where access and rigidity must be balanced. The relatively short length reduces overhang, improving dynamic stiffness and surface finish in internal machining. Where space is limited but accuracy remains critical, the compact footprint of this holder aids in achieving repeatable bore tolerances and consistent cycle times. The tool’s ISO designation and STI engineering reflect an industry‑oriented specification suitable for small to medium batch production.

Integrating the tool into workshop workflows

Adopting this boring bar aligns with a pragmatic, efficiency‑driven workflow: modular inserts for rapid service, an ER16 interface for broad compatibility and a left‑hand option for specific turning directions. For teams refining their process chain, the tool reduces complexity by matching widely available indexable insert formats and clamping standards. Where traceability or part changeover is required, the simple geometry and standard interfaces make programming and presetting straightforward, helping to reduce set‑up time and keep machines productive.
