I needed to upgrade and older drill press as well as needing a far more powerful unit to work with dense, thick and wild grained wood. This motor did the trick. I upgraded to a 3/4hp 1750rpm unit with a 56C frame that mated up perfectly with my drill press. The nice thing about it was that it was wired for my unit at 110 volts. It was clearly marked on the motor wiring cover as well and the rotation was exactly what I needed, although the instructions and "how-to's" for changing these options were clear and concise. Installation was quick and easy but the unit is heavy so keep that in mind. It started up perfectly. I have run it for about a month now and have used my largest Forstner bit a 3" bit in hard teak wood and it cut right through the 2 1/2" block with no slow down or hesitation. It cuts though Oak, hard Maple and any other wood I have needed to drill without a problem. It works very well and I would recommend these motors to anyone looking to replace, upgrade or change out a motor to the Grizzly units for fit, form and function. Shipping was quick and the packaging was very good as well.
