• All Drill Chucks are 100% inspected to ensure not to exceed a maximum total integrated run-out of 0.0016".
• The self-tightening feature automatically increases clamping, force proportional to increased torque to prevent tool shank slippage.
• All Components of the JKP Drill Chuck series that are exposed to wear have been hardened to maintain accuaracy and extend the tool and chuck life.
• The JKT Drill chuck series offers the addition of milled wrench flats to be used in applications where more tool clamping force is necessary. Clamping forces can be increased up to 3 times with light wrench tightening versus the standard hand tightening.
