Precision and process stability for internal bores

The S50U DDQNR configuration provides a stiff 50 mm shank and a controlled overhang that reduces deflection during interrupted cuts. With a nominal diameter of 63 mm and an overall length of 350 mm, this boring bar is engineered to deliver consistent concentricity when paired with appropriate holders. The 65 mm cutting height ensures correct insert seating and secure clamp engagement, which translates into more accurate hole diameters and fewer rework cycles. These attributes combine to reduce cycle variability and improve first-pass yield in serial production.

Compatibility and secure clamping for fast tool changes

Built to accept DN--1506 indexable inserts, the bar uses a proven clamping concept that enables quick index changes and repeatable positioning. The specification S50U DDQNR denotes a standardised interface compatible with common turning systems, so tool-change downtime is minimised. The included clamping-holder reference (15) and the right-hand cutting orientation ensure the assembly is aligned with standard lathe toolposts. For operations where tool-change speed and repeatability are priorities, this setup significantly reduces non-productive time and supports lean machining workflows.

Machining performance and application suitability

The tool geometry, with a cutting angle of 107.5°, balances cutting forces and chip flow for internal turning tasks, helping to avoid chatter on longer bores. At a weight of 5.166 kg, the bar provides mass for vibration damping while remaining manageable for installation and inspection. Its configuration suits a wide range of turning tasks where indexable inserts are preferred for economical edge changes — from prototype shops to light industrial production. The robust construction contributes to predictable tool life and simplifies tool management across the workshop.

FAQ

What insert type does this boring bar accept?
The K479TM boring bar is designed for DN--1506 indexable inserts, providing standardised seating and repeatable positioning for quick index changes.

Is the cutting direction configurable?
This model is specified for right-hand cutting; the S50U DDQNR form factor is intended for right-hand internal turning operations.

What are the key dimensions to check for holder compatibility?
Verify the 50 mm shank diameter, overall length 350 mm and 65 mm cutting height to ensure correct fit with the intended clamping system and toolpost.

Can the K479TM be used for long-reach boring?
The design offers stiffness for moderate overhangs, but for very long-reach boring operations a specialised long-reach bar should be considered; consult Metav Werkzeuge for parameter recommendations.

Which ISO designation identifies this bar?
The bar carries the S50U DDQNR designation, indicating the standardised shank and head geometry suitable for compatible holders.
