Cut down on runout and slippage under heavy cutting forces from 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.
