• For TNMG 1604 indexable inserts
• 25 mm shank diameter for rigid clamping
• 250 mm overall length, right-hand design

Higher cutting reliability through geometry and insert compatibility

The combination of a 107.5° cutting angle and support for TNMG 1604 indexable inserts provides a practical balance between approach access and effective chip control. This geometry reduces radial cutting forces in finishing passes, which in turn lowers the risk of chatter and contributes to improved surface quality. The use of standard indexable inserts enables quick regrinding or replacement, reducing downtime and supporting predictable cutting performance across batch work and single-part production.

Stable clamping and reach for consistent machining

Designed with a 25 mm shank and an overall length of 250 mm, the tool delivers the necessary rigidity for reliable bore finishing while offering sufficient reach for medium-depth operations. The specified 32 mm diameter and the ISO designation S25S MTQNR indicate a holder-form suited to secure clamping systems, supporting repeatable concentricity and minimised runout. Right-hand cutting orientation is integrated into the tool geometry to match standard lathe setups and common turning cycles.

Economical operation and simple integration into existing tooling systems

Acceptance of TNMG 1604 inserts and the familiar ISO holder format allow straightforward integration into established tool inventories, lowering tooling costs through the use of widely available inserts. The modular nature of indexable insert systems shortens service intervals since only the insert requires replacement or rotation, not the entire bar. With a mass of 0.942 kg the bar balances manageable handling with sufficient mass to dampen vibrations, supporting both finishing and light roughing tasks when combined with appropriate feeds and speeds.
