Minimize runout and slippage under heavy cutting forces from drill presses and Bridgeport milling 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 thread onto your machine’s drawbar for a secure connection.

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

Minimize runout and slippage under heavy cutting forces from drill presses, lathes, and milling 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’re keyless, so you can swap bits in and out with a quick twist of the sleeve. As torque increases, their grip will tighten.

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

Limit 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. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet JIS standards for compatibility across machines with BT spindles. They have a threaded hole that accepts retention knobs, so they connect to your machine’s drawbar system.

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. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet ASME standards for compatibility across machines with CAT spindles. They have a threaded hole that accepts retention knobs, so they connect to your machine’s drawbar system. 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.

Limit runout and slippage under heavy cutting forces from manual mills and older CNC mills. 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. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet ASME standards for compatibility across machines with NMTB spindles. They're also compatible with older Erickson quick change spindles. Internal threads in the shank connect to your machine's drawbar.

Twist the sleeve by hand to swap bits out quickly. The grip on the bit tightens as torque increases.

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

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.
