KA259TM A16M SDUCL Boring Bar – Left‑hand, internal coolant for DC-- 11T3 inserts (Teknik Makina)

The KA259TM is a left‑hand boring bar designed for CNC turning applications, engineered to accept SDUC‑style indexable inserts for internal‑coolant‑assisted machining on production and jobbing lathes

• Left‑hand cutting orientation
• Internal coolant delivery
• 16 mm shank for rigid clamping
• Compatible with DC-- 11T3 inserts

Stability and repeatable toolholding for production

A robust toolholder is essential for consistent results; the 16 mm shank and ISO designation A16M SDUCL provide a standardised fit that reduces runout and vibration. The combination of shank diameter and a 150 mm overall length balances accessibility and rigidity to support short‑reach boring and finishing passes. Specified mass (0.246 kg) and measured geometry help machine setup precision, which translates into reliable concentricity and longer insert life in serial production.

Controlled cooling and cleaner chip flow

Integrated internal coolant ensures coolant reaches the cutting zone directly, aiding heat dissipation and chip evacuation when paired with the appropriate insert geometry. The declared cutting angle of 93° supports stable engagement and predictable chip formation with DC‑series inserts. For applications where thermal control affects tolerances, the coolant channel improves surface finish and reduces the risk of built‑up edge, making the tool suitable for consistent, repeatable operations.

Flexible indexable insert system and left‑hand orientation

Designed for SDUC‑style indexable inserts (notably DC-- 11T3), the holder supports quick insert changes and cost‑effective tool management. Left‑hand cutting orientation is commonly required for specific lathe setups or insert geometries; this tool matches those needs without compromise. The compatibility with widely available inserts lowers tooling overhead and permits rapid adaption between roughing and finishing grades while maintaining a conservative tool inventory.

Practical integration in workshop workflows

This boring bar is intended for machinists and production engineers seeking a straightforward insert‑based solution for internal‑coolant turning tasks. Installation follows standard clamping practices for A16M holders; when replacing inserts, the modular concept minimises downtime and simplifies inventory. Combined with Metav’s distribution and technical support, the product integrates into maintenance cycles without elaborate retooling, supporting a dependable supply chain for everyday workshop demands.
