S32T MTUNL Boring Bar – MTUN for TNMG Indexable Inserts, 300 mm (Teknik Makina)

A S32T MTUNL boring bar engineered for left‑hand external turning with TNMG 2204 indexable inserts, offering a balance of rigidity and reach for medium‑duty lathe work

• Left-hand cutting orientation
• Holds TNMG 2204 indexable inserts
• 32 mm shank diameter for stability
• 300 mm overall length for extended reach

Improved stability and repeatable turning results

The design centres on a 32 mm shank and a solid mass (weight: 1.836 kg) to reduce vibration during cut entry and maintain concentricity over longer passes. A consistent toolholder geometry ensures that radial forces are managed, which reduces the likelihood of chatter and supports tighter tolerances. For production environments where repeatability matters, the reduced deflection translates directly into fewer rejected parts and less rework.

Broad insert compatibility for process flexibility

Compatibility with TNMG 2204 indexable inserts means the holder accepts a widely available insert grade and format, simplifying inventory and enabling quick insert swaps between roughing and finishing operations. The MTUN designation indicates the insert clamping and seating geometry tailored to triangular TNMG plates; this allows stable cutting edge support and straightforward orientation. The resulting setup time is minimised, improving overall machine utilisation.

Designed for practical machining tasks and clearance

The tool features a 60 mm cutting height and a 93° cutting angle, which together provide practical clearance and effective chip flow for external turning applications. The left‑hand (L) orientation is suited to operations where tool approach and feed direction demand left‑hand geometry. The 300 mm overall length delivers reach for off‑centre work or components with deeper shoulders, while the specified diameters (shank 32 mm, body 40 mm) assist with secure clamping in standard toolposts or holders.

Efficient operation and serviceability on the shop floor

Attention to clamping interface and standard insert type reduces downtime during tool changes and maintenance. The holder is compatible with standard TNMG inserts, so replacement parts and grades are readily available across suppliers. When set up correctly, the combination of rigid shank and established insert format supports higher cutting parameters and predictable tool life, which helps to lower cost per part in series production.

FAQ

What insert type fits this holder?
The holder accepts TNMG 2204 indexable inserts; the MTUN geometry is configured for stable seating of TNMG triangular plates in the S32T MTUNL boring bar.

Is the tool suitable for deep‑shoulder turning?
Yes. With a 300 mm overall length and a 60 mm cutting height, the holder provides extended reach for components with deeper shoulders while maintaining stability.

Which cutting direction does the holder support?
This tool is manufactured for left‑hand cutting direction to match lathe setups requiring left‑hand approach and feed.

How does the shank diameter affect performance?
A 32 mm shank increases bending stiffness compared with smaller shanks, reducing deflection and improving surface finish and repeatability during turning.

Who manufactures this tool and what is the SKU?
The tool is produced by Teknik Makina and listed under SKU K528TM; the ISO designation is S32T MTUNL.
