Perfectly centered Micro Chuck - diameter of 2.4mm (0.3/1.5mm) for thinnest drills.

The dynamically balanced, compact and streamlined design of our Mini Chuck allows it to spin true and vibration-free even at high speeds.
The shank and collet are precision machined from a single steel billet, thus insuring optimum concentricity and balance.
The chuck has a collet capacity.
This makes the task of centering these tiny drill bits in a hand or electric drill simple and easy.
The integral collet design allows your drill bit to spin true, thus avoiding tool wear.
Accurate, precise and strong, these chucks have a popular (#) shank and can be run at 35,000 RPM.
This is what makes the preferred choice for use with micro drill bits.
