K450TM S32T MTUNR Boring Bar — MTUN for TNMG indexable inserts, 32 mm shank, right-hand

The K450TM S32T MTUNR is a right-hand external boring bar designed for turning applications using TNMG 2204 indexable inserts, offering extended reach and stable support for medium-duty machining

• 32 mm shank for stable clamping
• Compatibility with TNMG 2204 inserts
• Right-hand cutting with 93° approach
• 300 mm overall length for extended reach

Maximise cycle reliability with rigid support and proven insert compatibility

The combination of a 32 mm shank and a supportive cutting geometry ensures consistent clamping and reduced vibration during external turning. Designed for TNMG indexable inserts, the tool supports reliable chip formation and predictable tool life; the 93° approach angle helps maintain favourable cutting forces and surface finish. These engineering choices translate into fewer interruptions on the shop floor and a measurable improvement in process stability for batch production.

Reach confined bores and external profiles with controlled balance

With a 300 mm overall length and a nominal diameter of 40 mm, the boring bar provides extended reach while retaining a practical balance for set-up and handling. The 60 mm cutting height stabilises the insert pocket, and the unit weight of 1.836 kg gives a tangible feel in the holder that aids repeatable mounting. For fixtures where access is limited, the extended length and robust shank reduce the need for multiple tool changes, helping workpieces to be completed faster with fewer set-up iterations.

Clear identification and traceable quality for process assurance

The tool carries the ISO-style designation S32T MTUNR and is listed under SKU K450TM, enabling straightforward procurement and inventory control. Compatibility with TNMG 2204 inserts simplifies tooling logistics by using an established insert family. Supplied by Teknik Cutting Tools and distributed via Metav Werkzeuge’s European quality filter, the component fits into a traceable, professional toolroom supply chain that supports continuous production and dependable reordering.

FAQ

Which inserts fit this boring bar?
The boring bar is designed specifically for TNMG 2204 indexable inserts; the MTUN pocket accepts standard TNMG geometry for predictable seating and chip flow.

Is the tool suitable for right-hand turning only?
Yes, the construction and cutting direction are specified for right-hand external turning operations as delivered.

What shank diameter is required for the holder?
The tool features a 32 mm shank, which requires a matching holder or collet system sized for 32 mm shanks.

How does the 93° approach angle affect cutting?
The 93° approach angle reduces axial cutting forces and supports stable engagement, improving surface finish and extending insert life under recommended conditions.

How is the product identified for reordering?
Reorder using SKU K450TM or the ISO-style code S32T MTUNR to ensure the correct boring bar configuration is supplied.
