SIR S16L boring bar — SIR for IR indexable inserts (Teknik Makina)

The SIR S16L is a right‑hand boring bar designed for internal turning with 11 IR indexable inserts, offering a compact 15 mm cutting diameter for precision machining in CNC lathe operations.

• Compatible with 11 IR indexable inserts
• Right-hand cutting for conventional turning
• 15 mm cutting diameter, 140 mm overall length
• Torx T8 fastener, M2.5x5.5 clamp screw

Precision that increases throughput and reduces scrap

The SIR concept combines a compact cutting geometry with a stable shank to deliver repeatable results in internal turning. Its compatibility with 11 IR indexable inserts allows for fast insert changes and consistent edge position, which reduces setup time and minimises scrap. The 15 mm cutting diameter and cutting height 32 mm provide a clear, measurable specification for process planning; operators can therefore predict material removal rates and cycle times with greater confidence. This technical clarity supports efficient production planning and higher first‑pass yields.

Secure clamping and balanced dynamics for reliable machining

Secure fixation is essential for accurate boring. The tool uses a Torx‑type drive and a small clamping screw to achieve repeatable clamp torque: Torx T8 with M2.5x5.5 screw specification ensures the insert seat is held firmly and reduces the risk of slippage during heavy cuts. At a mass of 0.207 kg, the bar contributes little to spindle imbalance while offering sufficient rigidity; the 16 mm shaft diameter helps transmit torque cleanly and keeps runout low. These characteristics combine to deliver stable cutting conditions and predictable tool life.

Easy integration into workshop workflows

With an overall length of 140 mm and an ISO designation of SIR S16L, the boring bar fits common toolholders and post‑holders used in turning centres. Indexable inserts make edge changes straightforward: only the small Torx screw needs to be accessed, shortening maintenance intervals and keeping machines on cycle. For teams new to indexable systems, an indexable insert is a replaceable cutting tip that allows the cutting edge to be renewed without withdrawing the entire tool, which lowers tooling costs and simplifies inventory management.

Applications, benefits and choice guidance

This right‑hand boring solution is suited to internal turning tasks that demand consistent geometry and quick insert replacement. The configuration is advantageous for finishing and semi‑finishing operations where dimensional tolerance and surface integrity are priorities. Selection of the matching 11 IR insert grade and geometry will determine performance on different materials; the bar itself provides the stable connection and precise positioning that the insert requires for optimal results.

FAQ

Which insert type fits this boring bar?
The bar is designed for 11 IR indexable inserts; matching the insert geometry ensures correct positioning in the SIR seat.

Is the tool suitable for finishing cuts?
Yes, the rigid SIR S16L configuration and its secure clamping make it appropriate for finishing and semi‑finishing internal turning tasks.

What is the required Torx key size for insert changes?
Insert changes use a T8 Torx key with an M2.5x5.5 clamp screw to secure the insert.

Will the bar fit standard toolholders?
The ISO designation SIR S16L and the 16 mm shaft diameter are compatible with common toolposts and boring holders that accept that specification.

How does the SIR design reduce machining downtime?
The indexable insert system allows fast tip replacement without removing the whole tool, and the Torx clamping system ensures repeatable torque for consistent set‑ups.
