JKP
Self-Tightening High Precision Keyless Drill Chuck
● Self-tightening mechanism automatically increases the clamping forces in proportion to the increase in torque during the drilling operation. This prevents tool slippage in clockwise rotation.
● For right-hand rotation applications only
● Use on high accuracy drill presses, jig borers, milling machines and production drilling equipment.
● All components exposed to wear are completely hardened to maintain accuracy and extend chuck life.
● Left hand rotation is available upon request
● Also available with through hole, for EDM machines, on demand
