SPI JT2S Ball Bearing Drill Chuck With No Key

SPI JT2S Ball Bearing Drill Chuck with No Key is a compact, keyless chuck designed for JT2S spindle tapers and a 2JT arbor. It accepts drill bits from 1/32" up to 3/8" in diameter and ships with a 2JT arbor for a secure, repeatable connection to compatible machines. The ball-bearing construction provides smooth operation and reliable grip without a key, enabling quick bit changes on benchtop drills or light milling setups. Mounting on JT2S spindles ensures broad compatibility with drills and small milling machines that use this taper, while the included 2JT arbor supports rigid engagement under load. This chuck is well suited for precise drilling tasks on metal, wood, or plastic where small-diameter bits are required and fast, tool-free bit changes are advantageous.
