The 6 Inch Soft Jaws (60° Pitch) with 12mm Keyway for Kitagawa Style Power Chucks (Vortex) — SJ06030B is a precision workholding accessory designed to fit Kitagawa-style power chucks. Engineered for secure, repeatable gripping during machining, these jaws help maintain accuracy across a range of parts.

Built for durability and easy customization, they balance robust performance with machinability so you can tailor the jaw geometry to your exact application, boosting consistency and reducing setup time on the shop floor.

• 60° pitch geometry: Delivers stable grip and uniform clamping pressure, minimizing part shift and improving repeatability during milling or turning.
• 12mm keyway for secure mounting: Positive drive and alignment prevent jaw rotation under load, ensuring consistent contact with the workpiece.
• Designed for Kitagawa-style power chucks (Vortex): Precise compatibility with popular chucks means fast, confident setup and reliable performance across jobs.

These soft jaws help you clamp parts quickly and securely, reducing setup time and part runout. The combination of durable construction and machinability means you can tailor the jaw shape to your part geometry, conserve tooling, and achieve tighter tolerances with fewer adjustments—delivering cleaner finishes, reduced scrap, and improved throughput on demanding machining operations.
