Reduce runout and slippage under heavy cutting forces from CNC machines. These chucks have an integrated arbor for a one-piece design that makes them more accurate and compact than chucks with a separate arbor. Made of hardened steel, they resist wear from repeated use. They meet DIN or ISO standards for compatibility across machines with HSK spindles.

You can route coolant through these chucks to extend the life of your bit and clear chips. To do so, you must install an HSK coolant tube. For automatic tool identification and tracking, these chucks have a hole for a small RFID tag.

To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.

Keyless chucks let you swap bits in and out with a quick twist of the sleeve. As torque increases, their grip will tighten. These chucks only tighten in the clockwise direction, so they may loosen under heavy reverse loads, such as during left-hand drilling. They’re balanced to G 6.3, so they’re good for most drilling tasks.

Keyed chucks use a worm-and-gear design to deliver exceptional grip on bits for the highest torque and accuracy when drilling in hard materials. They're so strong they can even be used for light duty milling in soft materials such as aluminum. Use their Torx key to tighten and loosen the chuck. Balanced to G 2.5, they vibrate 60% less than chucks balanced to G 6.3 for longer life under heavy use and high speeds.
