S32T MTUNL Boring Bar — MTUN for TNMG Indexable Inserts, left-hand, Ø40 mm (Teknik Makina)

A S32T MTUNL boring bar designed for left-hand external turning with TNMG 1604 indexable inserts, suited to stable medium-duty applications where repeatable seating and chip evacuation matter

• Compatible with TNMG 1604 indexable inserts
• Left-hand cutting for specialised turning tasks
• Shank diameter 32 mm for secure clamping
• Overall length 300 mm for extended reach

Precision where it matters: stable support for indexable inserts

The S32T MTUNL is engineered to provide consistent insert seating and predictable cutting behaviour when paired with TNMG 1604 indexable inserts. The combination of a 32 mm shank diameter and a body diameter of Ø40 mm reduces deflection under radial loads, which improves dimensional stability on external bores and shoulders. Translating insert geometry into reliable part tolerances is simplified by the tool's geometry, so cycle times can be maintained without compromising finish quality.

Designed for controlled chip flow and effective cutting

With a specified cutting angle of 93° and left-hand cutting orientation, the bar assists in directing chips away from the cutting zone, reducing recutting and potential surface damage. The cutting edge height of 60 mm aligns the insert correctly for secure clamping and dependable performance; this is particularly useful when swapping inserts during shift changes or in mixed-production environments where quick turnover is required. The tool's mass and balance also help to dampen vibration, supporting a better surface finish.

Practical installation and compatibility with clamping systems

The bar is supplied in an ISO designation of S32T MTUNL, making it straightforward to identify in tool libraries and draw lists. A shank diameter of 32 mm matches common toolholders, while the specified clamping-holder dimension "16" indicates the intended clamping interface for many standard holders. The mechanical setup is therefore uncomplicated, enabling rapid tool changeovers and minimising machine downtime when the insert index is required.

Built for workshop reliability and everyday use

Weighing 1.835 kg and measuring 300 mm overall, the component balances reach and rigidity for a wide range of external turning tasks. The construction supports repeated insert changes and routine handling without excessive wear, helping to preserve toolholder precision over time. For workshops seeking dependable tooling that integrates seamlessly into existing turning cells, this solution provides a robust, no-nonsense option that prioritises operational continuity and measurable results.
