Kingston’s CK Chucker is a rough turning beast that excels at high-volume facing, boring, and drilling of large-diameter workpieces. The powerful H6 350 turret sits atop a specially designed carriage with a larger contact surface area and uniquely designed box way cross slide. The heavily ribbed one-piece casting allows for high loading capacity, extreme rigidity, and vibration buffering. All of this and the 28″ wide 2 V-way bed provide the unsurpassed stability and heavy cutting capability Kingston built its name on. The Chucker comes equipped with a 4-speed headstock for maximum torque and comes front- and rear-chuck ready.
