The Jacobs Chuck Manufacturing Company maintains a global presence as a recognized leader in the design manufacture of precision tool and work holding devices for stationary equipment and portable power tools.
This Jacobs JK 130-3/8 Industrial keyless chuck is designed for industrial use (medium duty), available with screw fittings for professional portable drilling machines and with taper fitting for stationary drilling machines. The Jacobs JK 130-3/8 Industrial keyless chuck is equipped with automatic fitting for efficient, fast change of tools. A self-tightening mechanism automatically increases the grip in proportion to the increase in torque during the drilling to prevent the tool from slipping in a clockwise rotation. The chuck capacity is from 0.04-Inch to 0.512-Inch (1.0 Millimeter to 13.0 Millimeter) with 1/2-20 threaded mount. Like all Jacobs products, this product comes with a one year factory warranty.
