K367TM boring bar — MTWN for TNMG indexable inserts, S40T MTQNR, Ø40 mm shank (Teknik Makina)

The K367TM boring bar is an MTWN‑style holder designed for right‑hand turning with TNMG 1604 indexable inserts, suitable for medium to heavy‑duty CNC lathe applications

• S40T MTQNR shank Ø40 mm
• Compatible with TNMG 1604 inserts
• Overall length 300 mm, head Ø50 mm
• Right‑hand cutting, 107.5° cutting angle

Stable machining for consistent component finish

The MTWN design delivers a rigid tool geometry that reduces chatter and improves repeatability. With a Ø40 mm shank and the recognised S40T MTQNR interface, the holder provides enhanced clamping stability, which translates into a more consistent surface finish and longer insert life. The specified 107.5° cutting angle optimises the cutting engagement for typical lathe setups and helps maintain dimensional accuracy during extended production runs.

Quick insert compatibility and predictable tool setup

Compatibility with TNMG 1604 indexable inserts simplifies tool provisioning and shortens setup times on the shop floor. The head diameter of Ø50 mm and the clear designation as an MTWN style holder mean that tool offsets and mounting remain predictable across machines, lowering the risk of errors during tool changes. The right‑hand cutting orientation is explicitly marked to support correct installation and safe operation.

Designed for production reliability and easy integration

At 300 mm overall length and a measured weight of 2.807 kg, the bar balances reach with rigidity for a range of internal and external turning tasks. The robust construction suits series manufacture where stability and repeatability are priorities; the toolholder form factor is compatible with standard clamping systems used in modern CNC lathes. Where process reliability matters, this solution reduces rework and supports steady throughput.
