MTWN Boring Bar for TNMG Indexable Inserts — 32 mm shank, left‑hand (Teknik Makina)

MTWN Boring Bar designed for left‑hand internal turning with TNMG 1604 indexable inserts, suited to medium‑duty machining and constrained bores.

• Left‑hand cutting direction for internal turning
• Compatible with TNMG 1604 indexable inserts
• 32 mm shank for enhanced rigidity and stability
• 300 mm overall length for deeper reach

Stable performance for internal turning applications

The MTWN boring bar is engineered to deliver consistent stability during internal turning operations. With a 32 mm shank, the holder reduces tool deflection and helps to prevent chatter when machining interrupted cuts or long overhangs. The robust geometry translates into improved surface finish and longer tool life for the chosen indexable inserts. Specified mass and dimensions contribute to predictable dynamic behaviour: a balanced assembly minimises vibration, making the tool suitable for repeatable production tasks where process reliability matters.

Clear insert compatibility and cutting geometry explained

Compatibility with TNMG 1604 indexable inserts provides a broad selection of grades and chipbreaker geometries, allowing adaptation to materials from mild steels to stainless alloys. The tool features a 60 mm cutting height, which sets the insert projection and seating for secure clamping, while the cutting angle 107.5° influences chip flow and edge engagement—valuable when optimising feeds and speeds. This combination of insert format and geometry enables effective material removal rates while maintaining control over cutting forces for internal contours.

Practical integration, handling and shopfloor advantages

Designed with the ISO designation S32T MTQNL, the boring bar integrates into standard turret and tooling systems without modification. The 300 mm overall length provides reach for deeper bore work, and the listed mass of 1.821 kg signals a substantial construction that assists stability during machining. The clamp interface identified as Clamp size 16 supports secure screw tightening and repeatable clamping of the insert seat. Selection of this bar supports streamlined tooling setups: fewer changeovers, reliable insert seating and compatibility with common TNMG insert families reduce process interruptions and inspection effort.

FAQ

What insert type does the boring bar accept?
The MTWN boring bar accepts TNMG 1604 indexable inserts, offering a wide range of grades and chipbreakers for different materials and cutting conditions.

Is this tool suitable for left‑hand internal turning only?
Yes, the bar is configured for a left‑hand cutting direction and is optimised for internal turning tasks that require that orientation.

What are the key dimensions to consider for toolholders?
Relevant dimensions are the 32 mm shank diameter, 300 mm overall length, and 60 mm cutting height, which determine rigidity, reach and insert seating.

How does the ISO designation affect compatibility?
The S32T MTQNL designation ensures the boring bar fits standard turret and holder systems, simplifying integration with existing tooling setups.

Can the MTWN bar be used for deep bores?
With a 300 mm overall length and a robust shank, the bar is suitable for deeper bores where reach and stability are required; final suitability depends on machine setup and cutting parameters.
