This drill is one of my favorites. With a weight of slightly more than 70 pounds, it is a substantial piece of equipment, but the adjustable mag base makes it very capable without the need to be extremely precise in your initial placement. This drill was purchased for a variety of tasks in my job shop, including drilling large holes with standard twist drills (which I did not do at the time). In order to be certain that the problem is not caused by the drill chuck, I purchased a Jacobs chuck from MSC. I also checked the chuck with indicators to be sure it was not the chuck. However, after installing the chuck on my Milwaukee 4208 Mag drill, I noticed that the end of my 1/2″ -5″ long twist drill was running about.030″ (30 thousandths of an inch) out of round. In order to determine whether or not the chuck surface was out of round, I removed the chuck and adapting sleeve from the motor spindle. Much to my surprise, the spindle was out of round by.002″ (2 thousandths of an inch), so I replaced the chuck and adapting sleeves and checked the spindle again. I couldn’t believe that a brand new drill could have a spindle that wasn’t perfectly true to the rest of it. It was just under an eighth inch out of round at the end of the drill that I used in my chuck, which was 9 inches long and 7/8 inch wide. I called Milwaukee and informed them of the error, and to my surprise, their surprise matched mine, and they directed me to my local authorized repair shop, which was approximately an hour away. I dropped off the drill and explained my situation to the technician, who had the same reaction as I did: “never in my days have I seen one like this,” he said, adding that it could take up to a week to repair. I thanked him and walked out the door after leaving my name and phone number. It was four hours later that the repairman returned my call and informed me that my drill had not been damaged and that there was no error. According to him, after speaking with a different technical service representative than I had earlier in the day, he was informed that a spindle run-out of.002″ was acceptable and that their factory tolerance was in fact a spindle run-out of.006″. (6 thousandths of an inch, to be exact!. It was impossible for either the tech or myself to believe what we were hearing. Milwaukee is unconcerned about whether or not you drill a precise hole. I understand that some iron workers may not be concerned about their drill bit walking around an extra 1/8″ or 1/16″, but in my experience, this is absurd. At the spindle,.002″ isn’t much of a difference, but when you multiply that error by an 11″ twist drill, you have a problem. If you’re looking for a very accurate drill, you may have to deal with this issue. I’m going to fix mine myself and make it as accurate as possible by grinding the spindle out tool, chroming the adapter, and grinding it down to match the bore, but I wanted to make sure to post here to let everyone know that this is something you may have to deal with if you’re looking for a very accurate drill. Whether it matters to most people or not, if I have an issue with it, I’m sure another machinist somewhere will appreciate knowing what he’s getting himself into before he starts working on it.
With the exception of the spindle run-out issue, the drill is a complete and utter BOSS!. I adore the drill, and it has served me admirably since I first acquired it, and I am confident that it will continue to serve me admirably in the future.
Thank you for your time, and good luck with the drill. Yes, I most certainly am!
