Bohrstange KA260TM A20Q SDUCL – 20 mm shank, internal coolant | Teknik Makina

The Bohrstange KA260TM is a left‑hand boring bar designed for SDUC‑style indexable inserts, optimised for precise internal turning and reliable coolant delivery in industrial workshops.

• Left‑hand cutting, 93° cutting angle
• Built‑in internal coolant for tool cooling
• 20 mm shank diameter for secure clamping
• Compatible with DC-- 11T3 SDUC indexable inserts

Consistent chip control and extended tool life

The KA260TM boring bar combines a 93° cutting angle with integrated internal coolant to reduce heat at the cutting edge and improve chip evacuation. This configuration lowers the risk of built‑up edge and reduces cycle interruptions, which translates directly into higher productivity and less scrap. The use of SDUC indexable inserts provides repeatable geometry and faster index changes, supporting continuous production runs and simplified maintenance routines.

Stable holding and vibration reduction for accurate finishes

A 20 mm shank paired with a compact body diameter gives the tool a rigid setup that resists deflection during turning and boring tasks. The overall length 180 mm offers the necessary reach while maintaining stability, which helps to achieve uniform surface finishes and dimensional repeatability. Reduced vibration leads to longer insert life and fewer re‑work cycles, making the tool appropriate for demanding machine‑shop environments.

Clear compatibility and practical application guidance

Designed for use with DC-- 11T3 inserts in the SDUC format, the bar supports left‑hand cutting applications where the tool must cut when fed from right to left. Internal coolant supports applications that require effective cooling at the insert seat, such as medium to heavy interruption of cut or materials that generate heat. The tool’s configuration makes it suitable for conventional boring and face‑turning operations where indexable insert systems are preferred for rapid re‑conditioning of cutting edges.
