Boring bar S32T MTQNR – MTWN for TNMG indexable inserts (Teknik Makina)

The S32T MTQNR boring bar is a right‑hand toolholder designed for use with TNMG 1604 indexable inserts, offering rigidity and reach for medium‑duty external turning applications.

• S32T MTQNR shank Ø 32 mm
• 300 mm overall length for extended reach
• Compatible with TNMG 1604 indexable inserts
• Right‑hand cutting, 107.5° cutting angle

Greater stability for consistent surface finish

The S32T MTQNR boring bar is engineered to reduce chatter through a shank Ø 32 mm and a 40 mm outer diameter, delivering a stable connection between holder and insert. The 300 mm overall length provides the reach required for deeper external operations while maintaining rigidity; this combination helps to preserve tool life and improves repeatability of diameter tolerances across batches. For production environments, the reduced vibration directly translates into fewer reworks and more predictable throughput.

Faster changeovers and efficient machining with indexable inserts

Designed as an MTWN holder for TNMG 1604 indexable inserts, the tool supports quick insert replacement and economical tooling strategies. The compatibility with standard TNMG geometry allows use of a wide range of chipbreakers and grades, enabling optimisation by material and cut. The right‑hand cutting orientation and the 107.5° cutting angle balance clearance and cutting edge strength, which helps maintain stable cutting forces and longer edge life — a clear benefit when switching between roughing and finishing passes.

Seamless integration into workshop routines and process reliability

The toolholder's mass (approx. 1.821 kg) and ISO designation ensure predictable handling during set‑up and predictable balancing in rotating assemblies. The MTWN for TNMG indexable inserts format supports established clamping practices and simplifies inventory by aligning with commonly stocked TNMG inserts. For complex operations where fixture space and access matter, the boring bar’s geometry provides reach without excessive overhang, promoting safer toolpaths and easier programming for CNC lathes.

FAQ

Is this tool compatible with standard TNMG inserts?
The MTWN holder is compatible with TNMG 1604 indexable inserts; the design of the boring bar supports standard TNMG geometries and common chipbreaker options.

What is the shank size and how does it affect rigidity?
The shank Ø 32 mm of the S32T MTQNR provides increased stiffness compared with smaller holders, which improves cutting stability and surface finish when machining external profiles.

Which cutting direction is this tool intended for?
This boring bar is configured for right‑hand cutting, optimised for conventional turning directions on standard CNC lathes.

What reach does the tool provide for deep cuts?
With a 300 mm overall length, the tool offers extended reach for deeper external turning while maintaining a balance between overhang and rigidity.

How does the 107.5° cutting angle influence performance?
The 107.5° angle offers a compromise between clearance and edge strength, helping to maintain stable cutting forces and prolong insert life during mixed roughing and finishing operations.
