KA129TM Boring bar (A16M SDUCR) – SDUC for DC-- indexable inserts, right‑hand, through‑coolant by Teknik Makina

The KA129TM boring bar is a right‑hand indexable insert holder designed for precision turning and internal boring, offering through‑coolant capability and a compact shank for stable clamping and reliable chip evacuation.

• Through‑coolant for improved tool life
• Compatible with DC-- 11T3 indexable inserts
• 20 mm shank with 25 mm head diameter
• 180 mm overall length for deep bores

Stable cutting for consistent bore quality

The combination of a 20 mm shank and a 25 mm head diameter provides a rigid interface that reduces vibration during machining, resulting in improved roundness and surface finish. This holder’s A16M SDUCR ISO designation ensures straightforward integration with standard tool posts. The documented cutting angle 93° supports controlled engagement of the insert, so each pass delivers repeatable results — an advantage for batch production and quality‑sensitive applications.

Coolant delivery that extends tool life

Integrated through‑coolant directs cutting fluid precisely to the cutting edge, which aids chip removal and reduces thermal load on the insert. As a result, the indexable inserts run cooler and resist premature wear, improving process uptime. For workshops aiming to lower tooling costs, the improved tool life from effective coolant flow reduces the frequency of insert changes while maintaining machining performance.

Designed for straightforward workshop integration

With a total length of 180 mm and a compact shank, the holder fits many common tool stations without complex adaptation. The unit is specified for DC-- 11T3 indexable inserts and is configured for right‑hand cutting, allowing quick setup for standard turning and boring tasks. Where machine tool compatibility matters, the ISO designation and standard shank size simplify procurement and spare‑part management across diverse CNC fleets.

Practical benefits for production workflows

The boring bar’s geometry and internal coolant capability deliver measurable efficiency advantages: fewer interrupted cycles for tool changes and more consistent machining outcomes. The modest weight of the assembly keeps handling easy during tool changes, while the holder’s construct supports controlled chip flow thanks to its right‑hand orientation. These operational improvements contribute to smoother toolroom logistics and predictable production batches.

FAQ

Which inserts fit this holder?
The KA129TM boring bar is specified for DC-- 11T3 indexable inserts and is supplied in the A16M SDUCR configuration for straightforward mounting of those insert types.

Does the holder support through‑coolant machining?
Yes, the holder features through‑coolant delivery to the insert area, which improves chip evacuation and reduces thermal stress on the cutting edge.

What are the key dimensions to check for machine compatibility?
Check the 20 mm shank diameter and the 180 mm overall length when planning tool‑post mounting; the ISO designation A16M SDUCR also assists in confirming fitment.

Is the cutting direction suitable for common turning operations?
The unit is configured for right‑hand cutting, making it suitable for standard external and internal turning operations where that orientation is required.

What advantage does the 93° cutting angle offer?
A cutting angle of 93° provides an appropriate approach for controlled engagement and helps achieve consistent surface finish and bore geometry on many workpiece materials.
