These SJ215001 soft jaws are designed for Kitagawa‑style power chucks, specifically sized for large workpieces in the 15/18 inch class. With a 60° pitch and a 25 mm keyway, they provide secure, repeatable gripping and precise alignment during milling and turning operations. Crafted from high‑quality materials, these jaws are not only durable but also machinable, so you can tailor the contact surfaces to your exact part geometry and machining needs.

• Precision grip and repeatable accuracy: The 60° pitch ensures uniform contact across the workpiece, delivering consistent clamping force and minimizing runout for precise, repeatable results.
• Durable, machinable construction: Built from high‑quality materials that withstand repeated use, while remaining easy to machine into custom profiles to fit your parts exactly.
• Secure 25 mm keyway mounting for Kitagawa‑style chucks: The precise keyway interface provides a tight, vibration‑free fit on Vortex chucks, helping reduce movement during heavy cuts and boosting overall reliability.

In practice, these soft jaws help you hold diverse components securely without marring surfaces, speeding setup times and preserving tight tolerances. The combination of 60° contact, robust keyway mounting, and machinability gives you flexible, dependable holding power across a range of materials and geometries, enabling consistent quality and smoother throughput in demanding machining workflows.
