MTWN for TNMG Indexable Inserts — S50U MTQNR boring bar (Ø63 mm, 350 mm)

The MTWN for TNMG Indexable Inserts is a right-hand boring bar engineered for external turning applications with TNMG 1604 inserts, providing a heavy-duty shank and a geometry optimised for stable, repeatable chip formation.

• Right-hand turning for external operations
• Compatible with TNMG 1604 indexable inserts
• 63 mm outer diameter, 350 mm overall length
• Robust S50U MTQNR shaft, 50 mm shank diameter

Stable cutting performance for demanding turning operations

The design focuses on process stability by combining a substantial shank diameter (50 mm) with a large outer diameter (63 mm) and an overall length of 350 mm. This geometry reduces deflection during interrupted cuts and supports consistent concentricity in serial production. The ISO designation S50U MTQNR identifies a standardised interface for secure clamping; the heavier mass (weight 5.121 kg) contributes to vibration damping, which results in improved surface quality and extended insert life. Explanation of technical terms: a larger shank diameter increases rigidity, while the outer diameter and geometry influence how the tool presents the insert to the workpiece.

Predictable chip flow and repeatable finishes

With a defined cutting angle of 107.5° and compatibility with TNMG 1604 indexable inserts, the toolholder promotes controlled chip breaking and effective evacuation in general turning tasks. The right-hand cutting direction suits conventional turning setups. The combination of cutting geometry and insert fit improves reproducibility across batches, meaning fewer reworks and steadier cycle times — a rational benefit for production planning. Where material or feed ranges are critical, match the TNMG grade to the workpiece to balance wear resistance and toughness.

Practical integration and workshop suitability

The bar's ISO-style designation and the clear specification of shank and overall dimensions simplify tool selection and fixturing on lathes and turning centres. The item is intended for use with TNMG 1604 inserts; adapt the insert grade to the application (roughing, finishing, or mixed-duty). The specification includes a clamp-holder designation (value 16) for reference during tooling configuration. For workshops aiming to reduce supplier complexity, this robust holder reduces the need for frequent re-clamping and supports a predictable maintenance rhythm.

FAQ

Which insert type fits this boring bar?
The bar is designed for TNMG 1604 indexable inserts; select the appropriate TNMG grade for the material and cutting conditions.

What are the key dimensions to check for machine compatibility?
Check the 63 mm outer diameter, 50 mm shank diameter and 350 mm overall length against toolpost clearance and turret capacity.

Is the bar suited to heavy interrupted cuts?
The robust S50U MTQNR construction and substantial mass (5.121 kg) improve damping and make the bar suitable for heavier, interrupted turning routines when paired with the correct insert grade.

Does the tool have a specified cutting direction?
Yes — the tool is configured for right-hand cutting operations.

What ISO designation helps with clamping and replacement?
The S50U MTQNR ISO-style designation identifies the holder interface and assists with secure clamping and straightforward replacement.
