22-Piece Case Clamping collet set and drawbar

This 22-piece case clamping set is designed to clamp inside diameters ranging from 18mm to 40mm. They're ideal for securely holding watch cases, case backs, and bezels during repair and finishing.

Unlike traditional chucks, the collet system does not extend beyond the workpiece, allowing for significantly improved angular accuracy with less setup effort. This makes precision work easier and more efficient, especially in delicate watchmaking and fine mechanical tasks.
