L.S. Starrett 25SC14 Split Collet For 3 8 24 NF Lathe

Starrett 25SC14 Split Collet, English-thread 3/8-24NF, is a precision accessory in the Starrett 25SC lathe system designed to grip cylindrical stock by compression within compatible 25SC holders. The split-collet design allows the collet to clamp around a workpiece as the threaded interface is tightened, providing concentric contact when holding small-diameter stock. The collet’s overall length with threads is 1 inch, enabling predictable fit in standard 25SC setups and adapters that accept 3/8-24NF threads. The 25SC14 is part of Starrett’s split-collet lineup for lathe use and is intended for applications requiring secure clamping on round stock. Pair with the appropriate 25SC accessory and verify that your lathe or holder accepts 3/8-24NF threads to ensure compatibility with your spindle geometry and clamping range. This collet is suitable for use with compatible Starrett 25SC adapters or chucks designed to receive 3/8-24NF threaded split collets, enabling a compact, repeatable clamping solution for small-diameter turning work.
