MTENR for TNMG 1604 Indexable Inserts — Boring bar S40T, right-hand, 40 mm shank (Teknik Makina)

The MTENR for TNMG 1604 Indexable Inserts is a right-hand boring bar designed for turning operations using TNMG 1604 indexable inserts, intended for general workshop and industrial lathe applications where insert interchangeability and stable chip control are required

• S40T shank, 40 mm diameter
• Compatible with TNMG 1604 inserts
• 60° cutting angle for versatile turning
• 300 mm overall length, robust 2.8 kg weight

Stable clamping and insert compatibility for reliable production

The ISO designation S40T MTENR indicates a secure 40 mm shank suited to standard toolholders; this geometry delivers a predictable connection between machine and tool. With compatibility for TNMG 1604 indexable inserts, insert changes are fast and repeatable, reducing downtime. The 60° approach angle is optimised for common turning tasks, allowing consistent chip formation and easier tool-path programming. This combination supports steady cycle times and reproducible part quality.

Rigidity and overhang balance for improved surface finish

A 300 mm overall length paired with a 50 mm body diameter and a shank of 40 mm provides a sensible balance between reach and stiffness. The tool’s mass of 2.8 kg contributes to vibration damping in medium-duty operations; lower nuisance vibration helps to maintain surface finish and extends insert life. In practice, shorter overhangs reduce deflection — planning set-ups around the bar’s geometry enables operators to achieve dimensional stability with fewer rework cycles.

Efficient machining with predictable cut geometry

The 60° cutting angle and 60 mm cutting height yield a well-defined engagement geometry for turning applications, which simplifies process calculations for cutting forces and feed rates. Using standard TNMG inserts keeps tooling inventories compact and simplifies procurement. The right-hand cutting orientation ensures compatibility with most conventional lathes and turning cycles. For production-oriented shops, the result is fewer tool changes, clearer tool life estimation and improved overall throughput.

Easy integration into existing toolrooms and maintenance routines

The boring bar is deliberately specified to match common holder standards (ISO S40T), so mechanical integration is straightforward and setup time is reduced. Routine maintenance consists of correct torqueing in the clamping system and regular inspection of the insert seat; replacement inserts restore original accuracy without lengthy adjustment. If clarification is needed on holder selection or suitable insert grades, technical advice is available to ensure the component fits the intended machining task and machine capability.

FAQ

Which inserts fit this boring bar?
The MTENR for TNMG 1604 Indexable Inserts is designed specifically for TNMG 1604 inserts; insert interchangeability ensures quick replacement and consistent cutting geometry.

Is the bar right- or left-hand cutting?
This boring bar is configured for right-hand cutting operations, matching standard right-hand turning cycles on conventional lathes.

What are the key dimensions to check for holder compatibility?
Check the S40T shank size (40 mm), the overall length of 300 mm, and the clamping interface; these determine holder fit and acceptable overhang.

How does the 60° cutting angle affect machining?
A 60° approach angle delivers a balance between cutting force distribution and surface finish, suitable for many finishing and semi-finishing turning operations with TNMG inserts.
