Take advantage of a robust combination of rigidity and compatibility: the left-hand design and 40 mm shank ensure secure clamping and steady cutting forces, while compatibility with TNMG 2204 indexable inserts simplifies tooling logistics; order directly via Metav Werkzeuge or consult our specialists for application advice.

S40T MTUNL Boring Bar — 40 mm Shank, Left-hand for TNMG 2204 (Teknik Makina)

The S40T MTUNL is a left-hand boring bar designed for external turning operations on CNC lathes, optimised to accept TNMG 2204 indexable inserts and deliver stable results in medium to heavy-duty cuts.

• Stable 40 mm shank for secure clamping
• Compatible with TNMG 2204 indexable inserts
• 300 mm overall length for extended reach
• Left-hand cutting geometry for specific turning tasks

Improved rigidity for consistent cycle times

The solid design with a 40 mm shank and a 50 mm working diameter provides enhanced stiffness that reduces vibration and extends insert life. This stability translates into repeatable machining and shorter setup times on series production runs, helping to maintain cycle-time targets. The toolholder’s mass of 2.814 kg contributes to damping cutting forces without compromising manoeuvrability, which is particularly beneficial when precision and surface finish are priorities.

Designed around common inserts for lower tooling complexity

Engineered specifically for TNMG 2204 indexable inserts, the holder simplifies inventory and changeover processes. The S40T MTUNL accepts standard triangular inserts, permitting quick indexing and predictable chip control. The left-hand cutting direction and a 93° cutting angle ensure correct rake and clearance for many external turning tasks; this alignment reduces the need for multiple specialised holders and supports efficient production planning.

Practical reach and handling for workshop flexibility

With a 300 mm overall length and a defined cutting height of 60 mm, the bar provides the reach required for deeper bores and extended overhangs while remaining suitable for conventional external turning setups. The combination of reach and compatibility enables workshops to tackle a wider range of components without frequent tool changes. Clear specifications reduce programming uncertainty on CNC machines and make tool selection straightforward for operators and planners.

FAQ

Is the holder compatible with TNMG 2204 inserts?
Yes. The S40T MTUNL boring bar is specifically designed for TNMG 2204 indexable inserts, enabling fast insert changes and predictable chip control.

What is the shank diameter and why does it matter?
The holder has a 40 mm shank; a larger shank diameter increases rigidity and reduces vibration, improving surface finish and insert life during turning operations.

Can the bar be used for deep-reach turning?
The 300 mm overall length provides extended reach for deeper turning tasks while maintaining acceptable stiffness for many workshop applications.

Which cutting direction does the tool use?
This tool uses a left-hand cutting geometry, suitable when the tool must cut in the left-hand direction on the lathe.

What mounting information is relevant for CNC setup?
Key values for setup are the 40 mm shank, 300 mm overall length and 60 mm cutting height; these dimensions support reliable tool offsets and repeatable positioning.
