SIR S20P boring bar K337-7TM by Teknik Makina — 19 mm cutting diameter, 20 mm shank

A SIR S20P boring bar for right-hand turning, intended for use with 16 IR indexable inserts and machines accepting a 20 mm shank.

• Right-hand cutting for standard turning
• Fits 16 IR indexable inserts
• Shank Ø 20 mm for secure clamping
• Overall length 170 mm for extended reach

Stable cutting for consistent surface finish

The design focuses on delivering repeatable results in turning operations. The combination of a 19 mm cutting diameter and a 20 mm shank reduces deflection during cuts, which improves surface quality and dimensional stability on the workpiece. Using 16 IR indexable inserts means insert changes are fast and economical; the replaceable cutting edges maintain consistent geometry without the need for regrinding. This approach supports efficient cycle times and helps to lower total tooling costs over production runs.

Secure clamping and straightforward maintenance

Robust clamping is enabled by the shank size and the fastener system: the insert is secured with an M3.5x8.5 Torx screw, tightened using a T15 key, which ensures accurate seat contact and reliable torque transmission. The SIR S20P designation indicates the intended insert and holder interface, simplifying tool setup in the shop. With an overall length of 170 mm and a compact mass of 0.381 kg, the bar balances reach and rigidity, making maintenance and handling uncomplicated while preserving machining stability.

Integration into machining workflows

The bar is optimised for right-hand cutting applications and will suit conventional lathes and CNC turning centres that accept a 20 mm shank and IR-style inserts. Its ISO-related designation and standard fastening arrangement support compatibility with common indexable systems, so the tool can be introduced without complex adapter work. For operations requiring reliable insert changes and a predictable toolpath response, this turning bar provides a practical blend of accessibility and performance.
