Boring bar S50X DDUNR (K417TM) — heavy-duty external boring bar, 50 mm shaft, DN-- 1506 compatible

The Boring bar S50X DDUNR is engineered for demanding external turning applications where stability and reliable insert clamping determine dimensional repeatability and surface quality

• Right-hand cutting, robust construction
• 50 mm shaft diameter for high rigidity
• Compatible with DN-- 1506 indexable inserts
• 550 mm overall length, balanced weight

High rigidity for improved accuracy and surface finish

A robust toolbody delivers measurable advantages in routine turning operations: the combination of a 50 mm shaft and a 65 mm cutting height provides a stiff support that minimises deflection under heavy cut and improves dimensional repeatability. The substantial mass of 8.716 kg helps dampen vibration, which in turn reduces chatter and the need for secondary machining. For workshops aiming to tighten tolerances, this structural approach converts directly into fewer rejects and lower rework costs.

Clear insert compatibility and optimised cutting geometry

Designed for use with DN-- 1506 indexable inserts, the bar’s geometry supports consistent chip formation and evacuation. The 93° cutting angle is selected to balance cutting forces and edge strength, while right-hand cutting aligns with standard lathe setups. These characteristics make insert selection straightforward: matching the DN-- 1506 grade to the workpiece and speed profile results in predictable tool life and reliable surface quality. Explaining how geometry affects performance reduces specification uncertainty for production planning.

Reach, handling and workshop integration for efficient setups

With a 550 mm overall length and a main diameter of 63 mm, the bar offers extended reach for deeper bores or external overhangs while retaining the stiffness required for precise turning. The physical dimensions demand an appropriately rated holder and secure clamping; when the machine setup and fixture strategy are aligned to the bar’s size, cycle times remain consistent and tool change intervals become predictable. For complex setups, Metav’s technical resources can advise on optimal clamping and balance to maintain machining stability.

FAQ

Which inserts fit this boring bar?
The S50X DDUNR is specified for DN-- 1506 indexable inserts; matching insert grades should be selected according to the workpiece material and cutting conditions.

What is the shaft diameter and why does it matter?
The 50 mm shaft provides the stiffness necessary to reduce deflection during heavy cuts, improving dimensional accuracy and surface finish with the S50X DDUNR.

Is this tool intended for right-hand or left-hand turning?
This tool is designed for right-hand cutting, which suits conventional lathe configurations and standard programming.

How long is the boring bar and what does that mean for setup?
The overall length is 550 mm; longer reach requires careful clamping and machine stability to maintain precision during extended overhangs.

Can the S50X DDUNR be used for deep external boring?
Yes, the combination of the bar’s stiffness, 63 mm diameter and extended reach makes it suitable for external boring tasks that require both reach and rigidity.
