Jet Tools J-A5816 15" Variable Speed Floor Model Drill Press, 1 Phase/115V

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.

Features:

• 1/2" Drill chuck and arbor included
• 3" column diameter for maximum head support
• 6" stroke for deep hole application
• Full bearing support on quill for maximum spindle stiffness
• Handwheel speed adjustment of 400 to 5,000 RPM
• Large 2-1/4" quill for greater accuracy
