Deliver maximum clamping force and high torsional resistance for heavy-duty drilling applications with industrial-grade Gear Rim Chucks (keyed drill chucks). Engineered for mounting on stationary drill presses, pillar drilling machines, lathe tailstocks, and portable power tools, these classic keyed chucks utilize a precision gear rim key interface to tighten three hardened steel jaws. The gear-driven leverage allows operators to apply exceptionally high clamping torque, ensuring straight-shank drill bits, reamers, and counterbores remain solidly locked without slipping, even under high cutting loads and heavy vibration.
