Boring bar S25S MTENR — MTENR for TNMG 1604 indexable inserts by Teknik Makina — 60° cutting angle, right-hand

Boring bar S25S MTENR for precision turning and insert clamping; designed for TNMG 1604 indexable inserts and right-hand cutting in CNC turning applications

• S25S MTENR holder for TNMG 1604 inserts
• 60° cutting angle for versatile turning
• 25 mm shank for rigid clamping
• 250 mm overall length for deeper reach

Stable clamping for repeatable turning results

The S25S MTENR toolholder prioritises rigidity and repeatability. With a 25 mm shank and a nominal body diameter of 32 mm, the bar resists deflection under load, delivering consistent engagement of the TNMG 1604 insert. The robust geometry and clamping arrangement reduce vibration, which helps to extend insert life and maintain surface finish — a clear efficiency gain for batch and single-piece production alike. The design supports right-hand cutting and a 60° cutting angle, offering a balance between strength and access for common turning profiles.

Workpiece-focused performance and predictable tool life

Built for standardised indexable inserts, the holder enables fast insert changes and predictable machining cycles. The compatibility with TNMG 1604 insert geometry ensures familiar chip formation and stable cutting forces, which translates to lower setup times and predictable maintenance intervals. At a weight of 0.96 kg and an overall length of 250 mm, the assembly remains manageable in automated tool turrets while providing enough overhang for medium-depth turning tasks. This combination enhances process reliability and helps to reduce unplanned downtime.

Practical benefits for workshop and production planning

The toolholder’s 55 mm cutting height provides correct seating for TNMG inserts, simplifying tool presetting and reducing the need for shimming. The S25S MTENR designation identifies the shank and mounting form, assisting toolroom inventory management and preventing mix-ups during rapid tool changes. For operations migrating inserts across machines, the standardised interface and right-hand orientation streamline tool allocation and spare-part planning, supporting lean stock management and lower tooling costs over time.
