Meet the S20S-SDUCL-11: a 20mm steel shank boring bar built for left‑hand turning with DCMT11 inserts. Its screw‑on clamp and a 93° approach angle deliver stable, repeatable bore quality in precision machining applications.

• Shank size: 20 mm solid steel shank for rigidity and compatibility with common tool holders.
• Left-hand configuration: specifically designed for left‑hand turning operations.
• Insert compatibility: designed for DCMT11 style turning inserts to cover a range of boring and finishing tasks.
• Clamp system: Screw On Clamp provides quick, secure insert seating and easy changes.
• Approach angle: 93° approach angle optimized for cutting geometry and efficient chip evacuation.
• Construction: solid steel construction delivers stiffness and durability for demanding machining environments.
• Brand alignment: part of the Vortex SDUCL family, engineered for reliable performance in precision boring.

This boring bar is designed to deliver consistent hole diameters and smooth finishes by minimizing tool deflection and chatter. The quick‑change screw‑on clamp reduces setup downtime, making it suitable for production runs and shops that value repeatability. With its 93° approach and left‑hand orientation, it excels in internal boring and finishing passes on a range of workpieces, helping you achieve precise, repeatable results with DCMT11 inserts.
