Boring bar SIR S50U (K342TM) — 50 mm shaft, 350 mm overall length — Teknik Makina

The SIR for IR Indexable Inserts (K342TM) is a right-hand boring bar designed for stable heavy-duty turning with standard IR indexable inserts in industrial lathe applications

• SIR S50U design for high stability
• 50 mm shaft diameter for rigid set-up
• Compatible with 16 IR indexable inserts
• Right-hand cutting direction

Built for rigidity and consistent surface quality

The machining set-up benefits from a 50 mm shaft diameter and a substantial outer Ø54 mm section that together deliver increased stiffness and reduced vibration. This rigidity is converted into measurable process advantages: improved surface finish and extended insert life. The tool is specified for heavy turning tasks where stability is decisive; with a compact mass of 5.337 kg, inertia is controlled while maintaining structural robustness. The design supports consistent repeatability, which reduces scrap rates and rework across production batches.

Fast insert changes and standardised clamping for uptime gains

Compatibility with 16 IR indexable inserts and the matching clamping holder IR16 simplifies inventory and shortens changeover times. Insert retention is secured with a Torx system (Torx key T15; screw M3.5x11) and uses the TA060 mounting plate together with pass ring BSP010, so insert replacement is straightforward and reproducible. The right-hand cutting orientation is specified for conventional turning centres and is supported by common workshop practices; this standardisation reduces the need for bespoke tooling and speeds up maintenance cycles.

Practical dimensions and seamless machine integration

The bar’s 350 mm overall length and 48 mm cutting height are balanced to suit a wide range of lathe turrets and toolpost arrangements, offering a compromise between reach and stiffness. Its ISO designation SIR S50U denotes a machining tool that has been configured for indexable-insert turning systems, enabling easy matching with compatible holders and turret interfaces. The measured dimensions make it simple to plan fixture clearances and collision avoidance, while the compact profile supports efficient tool storage and handling in busy workshop environments.

FAQ

What insert type does this boring bar accept?
The SIR S50U boring bar (K342TM) is specified for 16 IR indexable inserts, using the IR16 clamping configuration for secure retention.

Is the bar suitable for heavy-duty turning operations?
Yes. The 50 mm shaft diameter and robust outer section provide the stiffness required for heavy turning tasks, supporting improved surface finish and longer insert life.

Which fasteners and accessories are required for insert mounting?
Insert retention uses a Torx system — key T15 and screw M3.5x11 — together with the TA060 plate and pass ring BSP010 for standardised assembly.

Can the tool be used on left-hand turning centres?
This item is manufactured for right-hand cutting direction; for left-hand operations, a correspondingly configured tool should be selected.

How does this boring bar integrate with turret toolholders?
With an ISO designation of SIR S50U and a defined 350 mm overall length and 48 mm cutting height, the bar is compatible with common turret interfaces and can be mounted using standard clamping systems
