Jacobs JKP100-J2 High-Precision Keyless Drill Chuck 0.020"-0.394" | 2JT Mount | Brand New

Achieve ultra-precise alignment and rapid bit changes on your high-accuracy milling machines, drill presses, and CNC machinery.

When production deadlines demand speed without sacrificing accuracy, the Jacobs JKP100-J2 High-Precision Industrial Keyless Drill Chuck (Part Number: 9681) delivers elite-level workholding performance. Specifically designed for high-accuracy applications on both conventional and CNC production equipment, this premium steel chuck offers a versatile 0.020" to 0.394" (0.5mm to 10mm) clamping capacity. Featuring a precision-machined Jacobs Taper 2 (2JT) mount, it integrates seamlessly into compatible high-end drill presses, jig borers, and production mills.

What sets the JKP100-J2 apart is its innovative, engineering-focused design. It features an integrated self-tightening function that automatically scales up its gripping force proportionally to the torque applied during drilling—safely eliminating tool shank slippage during heavy cuts. Built to endure rigorous industrial environments, every single wear component is fully hardened to preserve its certified 0.0016" maximum Total Indicated Runout (T.I.R.) accuracy over an extended operational lifespan.

Key Features & Benefits

• Brand New Condition: 100% authentic Jacobs Chuck equipment, arriving completely unused, pristine, and uncirculated in original factory packaging.

• Certified High-Precision Accuracy: Precision-tested and certified to a maximum T.I.R. of 0.0016 inches at half capacity, guaranteeing exceptional concentricity for tight-tolerance industrial holes.

• Torque-Responsive Self-Tightening: The internal mechanism self-locks tighter as drilling torque increases, firmly anchoring bits and preventing costly damage from shank slippage.

• Effortless Keyless Operation: Hand-tighten and release tooling in seconds. Drastically cuts down on cycle changeover times and maximizes your shop floor's daily productivity.

• Fully Hardened Core Components: All internal and external friction points exposed to heavy wear are entirely hardened, preserving its industrial tolerance and structural integrity for years.

• Universal 2JT Taper Integration: The industry-standard 2JT mount offers stable, vibration-free toolholding compatibility across a broad lineup of machine spindles and production drill heads.
