I got my shipment with great service by the driver who was very helpful. When I went to assemble the drill press it was suggested to lay it on its side and install the top part and then get three people to stand it up. I could not find three people so I stood it up by myself and when the blood and oxygen got back to my brain, I finally realized how big the drill press really was! I had reservations about the drill press because it was made in China but it looks to be good quality. The fit and finish was good and no sloppy joints. I'm very happy it went together so nicely. Really good stuff so I'm working on a second order! Keep up the good work and hope to see you at the tent sale! Also, very good service from all the people I talked to at Grizzly. A most excellent company to do business with. Not one cranky person at Grizzly. Good job and thanks!
I have had this drill press for about 4 years and I have put it though its paces. Itâ€™s OK, itâ€™s powerful, but it has flaws and limitations. I bought it originally for its 4 ¾â€ spindle travel because I wanted to drill accurate holes in 4x4 hardwood posts to accommodate a stainless wire cable system for the new guardrail on my deck. It worked well for this. I have since used it on various metalworking projects, including gentle milling. I have a Shop Fox sliding vise that works quite well, although it is a little sloppy. I have two main complaints about the drill press. First the belt changing and tensioning device is terrible. For example, it takes forever to switch speeds between drilling a pilot hole and the full size finish hole. The central idler pulley often hangs up, just to slow the process even more. Belt tension is accomplished by sliding the motor backwards horizontally (in theory). In fact, the slides are so sloppy that the motor rotates skywards so that the axis is tilted causing excessive belt wear, especially with the small, slow speed pulley size. Also, during slow speed, high torque applications the head will stall due to belt slippage. My second complaint is about the red knobs at the end of the feed spokes. These are mounted on flimsy plastic bushings all of which have cracked causing the knobs to fall off. Fortunately the spokes have 12mm threads which allowed me to machine replacement aluminum bushings.
Overall, despite the limitations, I would recommend this tool for the price.
As others have described this machine is a beast. I used my engine hoist and a piece of 2" webbing strap (use a Water Knot) to slowly lower the head onto the tube. I highly recommend this stress free, muscle free method. The base, table, and tube are not a concern for one person to lift. But as a complete assembly, maneuvering this DP into its final position is hard! The information / manual, states that the machine works on either 110 or 220 BUT, the unit comes with a 3 wire cord (line-line-ground). So you can't run the unit on 220 AND use a light. Good news is 110 seems sufficient, and later on I will add a second cord just for the light. I would recommend a 5/8 T-Slot clamping kit (like G1076) because this DP could spin a tank and a good drill vise (such as Wilton 13402).
really like this unit, belts delivered with it are junk, guard went in the can immediately, but it is solid!
The power of this is phenomenal I am truly satisfied w this machine does need a key holder built it
This is the perfect drill press for the home shop. Nothing fancy just right. The big table is perfect for holding a vice or large items. The speed change is a bit of a nuisance but it didn't cost $2000 either.
