The Tobler TMDI-3 ST1447 is a precision collet-style clamping head designed for holding round workpieces or tooling shanks in machine tools. It features a segmented conical body with longitudinal slots that enable expanding or contracting clamping action, a rear mounting flange with threaded holes, and a central draw-bolt arrangement. These units show light handling marks but remain in good used condition.

Condition & Testing

Both units are in used condition with light handling marks and no corrosion. Surfaces retain their ground finish and parts appear functionally complete.

What's Included

Two matching collet clamping heads/mandrels, one small brass or bronze stepped shaft/bushing with internal thread, one flanged ring segment (wrapped in plastic), socket-head cap screws (installed), and one printed paperwork sheet with technical sketch.

Tobler manufactures precision toolholding and clamping systems for CNC machining applications.
