Boring bar — MTENR for TNMG 1604 indexable inserts, Ø50 mm shank, 350 mm length (Teknik Makina)

A boring bar (S50U MTENR) designed for right-hand turning operations using TNMG 1604 indexable inserts, offering extended reach and stable clamping for metalworking applications

• Compatible with TNMG 1604 indexable inserts
• Ø50 mm shank for secure clamping
• 350 mm overall length for deep reach

Stable geometry for consistent material removal

The tool's geometry, defined by the 60° cutting angle and an optimised insert pocket, delivers predictable chip flow and reduced vibration during turning. As a result, surface finish and dimensional repeatability are improved when machining common metals. The use of standard indexable inserts allows quick index changes, lowering set-up time and ensuring consistent cutting conditions across production runs.

Secure clamping and rigid toolholding

A Ø50 mm shank provides a high clamping surface for standard toolholders, increasing stiffness at the tool-to-holder interface and reducing deflection in interrupted cuts. The S50U MTENR designation indicates a robust shank and holder fit compatible with typical lathe toolposts, which supports stable finishing passes and longer tool life under moderate cutting forces.

Compatibility that simplifies tooling logistics

Designed specifically for TNMG 1604 inserts, the boring system standardises the cutting edge across turning operations. Using widely available indexable inserts simplifies spares management and reduces inventory complexity. The option to run common grades of TNMG inserts enables fine-tuning of wear resistance and surface quality without replacing the boring bar itself.

Reach and balance for industrial turning tasks

With a 350 mm overall length and an outside diameter of 63 mm, the bar is suited for deeper internal and external turning where accessibility is required. The specified cutting height of 70 mm aligns the insert seat for proper rake and clearance, helping to maintain cutting stability over extended overhangs. The component's mass and design balance contribute to reduced chatter and a steadier machining process.
