Product Details
These JET drill presses utilize a variable-speed motor with a stepped-pulley system and are equipped with a continuously variable transmission that allows for use at a wide range of speeds, including the capability to change speed during operation. A scale-marked hand wheel aligns with the desired machine speed and is mounted to a reduction gearing system for precise operator control, adjusting the gearing ratio between the motor's fixed pulley and the output shaft's variable pulley to modify the chuck's speed. A tensioner pulley is included in the belt transmission to either take up or release slack in the belt as speed changes. The features include speeds ranging from 400 to 5000 RPM, handwheel adjustment for setting speeds, a large 2-1/4 quill for enhanced accuracy, a 3-inch column diameter for maximum spindle stiffness, a 6-inch stroke for deep hole applications, an accurate depth stop for precise hole depths, a 1/2-inch drill chuck and arbor, and a safety collar.
