1. How a Collet Works
Unlike a standard 3-jaw drill chuck (which grips at three points), a collet has longitudinal slits. When you tighten it, the sleeve contracts uniformly, providing 360-degree contact.
-
Precision: Because it grips the tool all the way around, it keeps the tool perfectly centered.
-
High RPM: Due to their balanced, lightweight design, collets can spin at much higher speeds than standard chucks without vibrating.
