S25R ST‑CR boring bar — for TC-- 16T3 indexable inserts, shaft Ø 25 mm

A robust S25R ST‑CR boring bar designed for right‑hand cutting operations, compatible with TC-- 16T3 indexable inserts for precise internal turning and finishing in production and workshop environments.

• Right‑hand cutting direction
• Shaft diameter 25 mm for rigid support
• For TC-- 16T3 indexable inserts

Consistent bore quality through proven insert compatibility

The combination of a 25 mm shaft and compatibility with TC-- 16T3 indexable inserts provides a predictable machining setup that reduces variability between batches. The tool's 50 mm cutting height and 60° cutting angle are coordinated to deliver uniform chip formation, which in turn improves surface finish and repeatability. For production environments where cycle‑to‑cycle consistency matters, this indexable‑insert arrangement simplifies tool changes and inventory management while maintaining a high level of machining accuracy.

Stable shank and balanced geometry for reduced vibration

A compact overall length of 200 mm together with a 32 mm diameter profile and a mass of 0.772 kg contributes to the bar's inherent stability. Reduced overhang limits deflection and vibration, which leads to better concentricity and longer insert life. The mechanical balance and firm clamping reduce the need for additional damping measures, so operators and CNC programmers can expect fewer rejects and longer uninterrupted cutting sequences in both prototype and serial runs.

Efficient chip control and reduced downtime

Engineered for indexable inserts, the system allows rapid replacement of cutting edges without full tool withdrawal, improving uptime in the workshop. The right‑hand cutting orientation aligns with common lathe setups, enabling straightforward integration into existing processes. By using standardised indexable inserts, tooling costs can be optimised: worn edges are replaced instead of the entire tool, which supports predictable maintenance cycles and cost‑efficiency in the medium to long term.

Practical integration, handling and workshop benefits

The boring bar's S25R ST‑CR designation reflects its ISO‑style mounting and compatibility with common clamp holders, including the nominal clamp designation 16. This makes tool changeovers and inventory control simpler for procurement and floor staff. Metav's emphasis on accessible precision means that suppliers and smaller workshops benefit from a product filtered for European quality standards and supported from the Emmerich hub.

FAQ

What insert type is required for this boring bar?
The boring bar is designed for TC-- 16T3 indexable inserts, ensuring standardised replacement and predictable cutting behaviour.

Is the bar suitable for right‑hand turning only?
Yes, the tool features a right‑hand cutting orientation as specified in the product data.

What are the key dimensions to check before ordering?
Check the shaft diameter (25 mm), overall length (200 mm) and the cutting height (50 mm) to ensure compatibility with the machine tool and clamp holder.

How does the bore finish benefit from this design?
A compact, well‑balanced shank and a 60° cutting angle contribute to reduced vibration and consistent chip evacuation, which together improve bore surface quality.

Can the bar be integrated into existing toolholders?
The bar uses a standard S25R ST‑CR mounting style and a clamp designation of 16, which allows integration into compatible holders and existing setups.
