MTUN for TNMG Indexable Inserts – Boring bar S40T MTUNR (Ø50, 300 mm) by Teknik Makina

The MTUN for TNMG Indexable Inserts is a right-hand boring bar for external turning, engineered for secure TNMG 2204 insert seating and medium‑duty CNC applications

• 40 mm shank for stable clamping
• Compatible with TNMG 2204 inserts
• 60 mm cutting height for deep overhangs
• Right-hand cutting, 93° cutting angle

Greater rigidity for consistent turning accuracy

The combination of a 40 mm shank and a 50 mm diameter body gives the toolholder elevated torsional stiffness, which reduces vibration during cutting and extends insert life. With an overall length of 300 mm and a mass of 2.814 kg, the construction balances reach with stability, enabling reliable external turning on standard CNC lathes. The S40T MTUNR ISO designation ensures compatibility with common toolholders and simplifies procurement and replacement cycles.

Faster set-ups and optimised chip control

Designed for TNMG 2204 indexable inserts, the MTUN configuration secures inserts with consistent clamping force, shortening insert changes and set-up time. The 93° cutting angle delivers clearance for effective chip evacuation and helps to avoid rubbing on interrupted surfaces, so finishing passes remain predictable. This focus on insert compatibility and chip flow supports higher productivity and reduces scrap rates in batch production.

Practical fit for workshop workflows

The right-hand feed and defined cutting geometry make the boring bar suitable for conventional turning operations and many CNC turning programmes. The 60 mm cutting height allows larger overhangs without immediate loss of rigidity, useful for components with stepped diameters. With a clamping holder designation of 22 and the standard ISO shank format, integration with existing fixtures is straightforward, helping to centralise tooling and lower the number of special holders required.

FAQ

Which indexable inserts fit this boring bar?
The MTUN for TNMG Indexable Inserts is designed for TNMG 2204 inserts, offering reliable clamping and straightforward insert replacement for series production.

What are the key dimensions to consider when selecting a holder?
Key dimensions are the 40 mm shank diameter, 50 mm body diameter and the 300 mm overall length; the S40T MTUNR designation also guides compatibility with standard toolholders.

Is the cutting direction right-hand or left-hand?
This tool is configured for right-hand cutting and features a 93° cutting angle to support effective chip evacuation during right-hand turning.

How does the 60 mm cutting height benefit machining tasks?
The 60 mm cutting height increases the effective cutting envelope and permits deeper overhangs while maintaining reasonable rigidity for medium‑duty turning operations.

What does S40T MTUNR indicate for mounting and use?
S40T MTUNR is the ISO-style shank and configuration code that identifies the shank size and MTUN insert arrangement, simplifying integration with compatible holders and machines.
