Boring bar K337-4TM — SIR S16K holder for 11 IR indexable inserts, 12 mm dia by Teknik Makina

The K337-4TM is a compact boring bar designed for precise internal turning with 11 IR indexable inserts, suitable for right-hand cutting applications in production environments.

• 12 mm cutting diameter for fine boring
• Compatible with 11 IR indexable inserts
• 25 mm cutting height for stable engagement
• S16K shaft with 16 mm shank diameter

Precision where it counts: consistent bore quality with every pass

The compact design of this boring bar ensures repeatable diameters and stable tool engagement in serial work. The combination of a 12 mm cutting diameter and 25 mm cutting height enables secure seating of the insert and predictable chip control; as a result, runout is reduced and surface finish is improved. Insert clamping is achieved with a standard M2.5x5.5 screw and T8 Torx key, enabling quick, toolroom-friendly replacement without special fixtures.

Faster set-up and steady performance on the machine

A 16 mm shank (S16K) delivers the necessary rigidity for common turning and boring cycles while keeping the overall tool length compact at 125 mm. The modest mass of 0.167 kg facilitates rapid tool changes and reduces carriage inertia during short operations, supporting higher throughput in batch production. The holder is specified for right-hand cutting and is optimised for indexable insert economics, lowering tool consumable costs and easing inventory management for workshops and subcontractors.

Simple maintenance, minimal downtime

Maintenance and serviceability are straightforward: the insert pocket is designed for 11 IR format plates and is secured with the supplied Torx screw type M2.5x5.5, operated with a T8 key. This standardised fastening reduces spare-part variety and simplifies staff training. The bar’s ISO designation SIR S16K clarifies mounting and compatibility, allowing compatibility checks with toolholders and turret systems to be completed quickly and reliably.
