Boring bar SIR S16M by Teknik Makina — compact design, IR16 compatibility

the Boring bar SIR for IR indexable inserts is a right-hand tool designed for internal turning with 16 IR inserts, offering a compact 150 mm length for confined setups

• SIR S16M for 16 IR indexable inserts
• 16 mm shank for secure clamping
• 150 mm overall length for compact set-ups
• Right-hand cutting for standard lathe operations

Consistent accuracy through rigid shank and insert compatibility

The bar is engineered to provide consistent accuracy in internal machining by combining a 16 mm shank with the SIR mounting geometry. Compatibility with IR16 indexable inserts means that insert seating and repeatability are optimised, which directly improves concentricity and reduces scrap rates. The construction emphasises stability under load so that cycle times remain predictable and tool life is extended. For production environments where repeatability matters, this configuration supports predictable tolerances and smoother process control.

Fast, secure insert changes and low-maintenance operation

Maintenance and tool changes are simplified by a practical fastening concept: a Torx T15 interface and an M3.5x8.5 fixing screw ensure secure retention while allowing quick replacement of inserts. The cutting height 32 mm provides the correct seat geometry for IR inserts, minimising the need for shimming or complicated adjustments. The compact 150 mm overall length reduces overhang, lowering vibration potential and improving surface finish. These features combine to reduce downtime and make routine servicing straightforward without requiring specialised equipment.

Practical workshop benefits and typical applications

Designed primarily for internal turning applications on conventional lathes and CNC turning centres, the bar is suitable where a right-hand cutting direction is standard. The tool supports operations such as boring, internal profiling and light face-turning using indexable carbide inserts. Its modest mass and reduced overhang support higher feeds than longer, more flexible assemblies, delivering improved material removal rates and consistent surface quality. For tailored tool selection or machining strategies, Metav’s technical advisers can provide guidance to match the bar’s geometry to the specific insert grade and substrate.

FAQ

Which insert size fits this boring bar?
The bar is designed for IR16 indexable inserts; use inserts specified for IR16 seating to ensure correct fitment.

What is the shank diameter and why does it matter?
The shank diameter is 16 mm, providing a rigid connection to the toolholder and reducing deflection during internal turning.

Is the cutting direction suitable for standard lathes?
Yes — the tool has a right-hand cutting direction, compatible with standard right-hand internal turning operations.

What fasteners are required for insert clamping?
Insert retention uses a Torx T15 interface with an M3.5x8.5 fixing screw as supplied or specified for IR16 inserts.

Can this bar be used in compact or confined setups?
The 150 mm overall length and compact SIR design make it suitable for constrained workspaces where reduced overhang is required.
