Boring Bar K337-3TM (SIR S10H) by Teknik Makina — for 11 IR indexable inserts, Ø12 mm, 100 mm length

Boring Bar K337-3TM designed for internal turning with the SIR system; compact toolholder for workshop and CNC lathe applications with right-hand cutting

• Fits 11 IR indexable inserts
• Shank Ø10 mm, body Ø12 mm
• Cutting height 20 mm for accurate seating
• Torx screw M2.5x5.5, key T8 supplied specification

Precise geometry for repeatable internal turning operations

The compact SIR S10H toolholder provides a rigid, low-mass solution for internal machining where space and repeatability matter. With a Ø12 mm body and a shank Ø10 mm, the unit keeps the centre of gravity close to the spindle, reducing vibration and improving surface finish on internal bores. The measured cutting height 20 mm ensures correct insert seating; this translates into consistent tool life and fewer re-adjustments between jobs. The lightweight construction (approx. 0.063 kg) also reduces spindle load, which is especially relevant for high-speed smaller-capacity setups.

Secure insert clamping and quick indexable changes

Clamping is achieved with a Torx screw specified as M2.5x5.5, tightened with a T8 driver for positive, reproducible clamping torque. Designed for 11 IR indexable inserts, the holder accepts standard IR platings and seat geometries, enabling fast replacement and minimal downtime. The right-hand cutting orientation supports conventional lathe setups and predictable chip flow. Clear mechanical interfaces reduce adjustment time, making the toolholder suitable for series work and frequent insert changes on production lines.

Workshop integration and practical benefits on the shopfloor

At an overall length of 100 mm, the toolholder is compact enough for tight internal operations yet long enough to access recessed features. The ISO designation SIR S10H signals compatibility with the SIR clamping family, facilitating standardisation across a tooling estate. As a ready-to-fit component, the bar simplifies inventory management: the same holder geometry can be used with compatible insert grades, so tooling diversity is reduced while maintaining machining flexibility. The construction supports stable, repeatable results on internal turning tasks without extensive machine setup.

FAQ

What insert size does this toolholder accept?
The toolholder accepts 11 IR indexable inserts; it is designed to match the seating geometry of standard IR inserts for reliable clamping.

Which screw and driver are required for clamping?
Clamping uses an M2.5x5.5 Torx screw tightened with a T8 key for repeatable seating and secure retention.

Is the cutting direction suitable for conventional lathes?
Yes, the toolholder is specified for right-hand cutting and is compatible with standard lathe orientations and tooling setups.

What are the key dimensions to check for machine compatibility?
Key dimensions are Ø12 mm body, shank Ø10 mm, and overall length 100 mm; verify these against the machine clearance and toolpost capacity.
