Jet 15 in. 230-Volt/460-Volt Variable Speed Floor Drill Press

These JET Drill Presses use a variable-speed motor with the stepped-pulley system, and come equipped with a continuously variable transmission. This enables use at a wide range of speeds, as well as the ability to change speed during operation. A scale-marked hand wheel that matches the desired machine speed is mounted to a reduction gearing system for precise operator control. This adjusts the gearing ratio between the motor's fixed pulley and the output shaft's variable pulley, changing the speed of the chuck. A tensioner pulley is implemented in the belt transmission to take up or release the slack in the belt as the speed changes.Full bearing support on quill for maximum spindle stiffnessHand wheel speed adjustment of 400 RPM to 5,000 RPMLarge 2-1/4 in. quill for greater accuracy3 in. column diameter for maximum head support6 in. stroke for deep hole applicationAccurate depth stop for precise hole depths1/2 in. drill chuck and arbor includedSafety collar
