Teknik Makina S50U MTUNR Boring Bar – MTUN for TNMG indexable inserts, 50 mm shank

A S50U MTUNR boring bar designed for right-hand external turning, ideal where stiffness, repeatable insert seating and extended reach are required.

• 50 mm shank for stable clamping
• Compatible with TNMG 2204 inserts
• 65 mm cutting height for deep cuts
• 350 mm overall length for extended reach

Increased rigidity for consistent surface finish

The combination of a 50 mm shank and a solid construction reduces vibration and improves stability during external turning. Reduced chatter leads to a better surface finish and longer insert life, which in turn lowers tooling costs and machine downtime. The ISO designation S50U MTUNR indicates a standard interface for secure mounting, guaranteeing predictable behaviour under moderate to heavy cutting conditions and simplifying integration into existing tool holders.

Reliable insert seating and efficient chip control

Designed specifically for TNMG 2204 indexable inserts, the holder provides a secure seating geometry that supports repeatable cutting results. The 93° cutting angle and 65 mm cutting height promote controlled chip flow and reliable cutting edge engagement, reducing the risk of unexpected insert movement. This combination is particularly effective for finishing and semi-finishing passes where dimensional consistency and repeatability are essential.

Reach and tool geometry for versatile external machining

With a 350 mm overall length and a tool diameter of 63 mm, the tool balances reach with rigidity to enable access into deeper workpieces without excessive deflection. The right-hand cutting orientation is optimised for standard lathe setups, providing straightforward use in conventional turning operations. The tool’s mass and dimensions make it suitable for medium-duty to demanding external boring tasks where a longer tool overhang is required while maintaining acceptable stiffness.

Practical integration and operational benefits

The bar’s compatibility with standard TNMG inserts simplifies inventory and reduces preparation time at the machine. A measured weight of 5.145 kg reflects its robust build and contributes to stable cutting dynamics once mounted. For production environments the reliable geometry and standard interface reduce set-up variation, supporting consistent cycle times and predictable maintenance intervals—factors that improve overall process efficiency and quality assurance.
