The S20S-SDQCR-11 20mm Steel Shank Boring Bar is a precision tool designed for right‑hand turning with DCMT11 inserts. Built for rigidity and dependable performance, it delivers stable, repeatable boring results in demanding setups.

• Shank diameter: 20 mm steel shank engineered for compatibility with common tool holders.
• Material: Solid steel construction for enhanced rigidity, stability, and long service life.
• Insert compatibility: Specifically designed for DCMT style turning inserts (DCMT11).
• Clamp system: Screw On Clamp provides secure insert seating and quick changeovers.
• Approach angle: 108° approach angle to improve contact geometry and reach in tight features.
• Orientation: Right-hand configuration optimized for standard turning workflows.
• Brand: Vortex—trusted tooling designed for consistent performance in shop environments.

This boring bar pairs a robust solid steel shank with a reliable screw‑on clamp to minimize insert movement and vibration. The 108° approach angle expands your cutting envelope, enabling cleaner entrances into pockets and shoulders while maintaining good chip control. Suitable for DCMT11 inserts, it supports a range of finishing and preparatory passes with predictable wear and repeatability—ideal for machinists who value precision, stability, and efficient tool changes in small-diameter boring tasks.
