Description

The Vortex Boring Bar Pin Lock (Steel Shank, 93 Deg) S25R-PDUNR11 is a rugged solution built for machinists who demand consistent precision when using DNMG1104 inserts (PDUNR). Its 93-degree nose and secure pin-lock interface deliver stable, reliable performance across turning and boring operations.

  • Steel shank construction: A rigid, durable shank that resists flex and vibration for true bore geometry over long machining runs.
  • 93-degree nose geometry: Precisely matched to DNMG1104 inserts, optimizing seating and improving corner radii control for accurate bores.
  • Pin-lock insert retention: A secure locking mechanism that minimizes insert movement during heavy cuts, reducing chatter and interruptions.
  • PDUNR/DNMG1104 compatibility: Specifically designed to work with PDUNR inserts for dependable, repeatable performance.
  • Versatile for turning and boring: Suitable for roughing and finishing passes, delivering stable results across a range of bore diameters.
  • Precision seating and alignment: Tight tolerances ensure consistent insert alignment and dependable surface finish.

When setting up your Vortex boring bar, pair it with the right components to lock in precision and speed. Explore these commonly used accessories to streamline setup and enhance performance:

The Vortex Boring Bar with Pin Lock delivers tangible advantages in real-world machining. The rigid steel shank minimizes deflection under load, helping you maintain consistent bore diameters and smooth finishes. The pin-lock retention keeps inserts securely seated through demanding passes, reducing the need for rework and downtime. This makes it a reliable choice for producing precise internal bores, housings, and bushings, where repeatability matters most. By combining robust construction with purposeful geometry, you gain predictable tool life, clearer surface finishes, and more efficient setup across both roughing and finishing operations.
