Another Drill Doctor Revisited...

"Thanks to Bob Engelhardt, I googled "Darex Drill Dcotor" this morning. The company is now "Professional Tool Manufacturing". I called there 800-597-6170 number and got a real human being right away.

Even though I've had my machine for a number of years (hadn't ever used it until a couple of days ago, they are sending me new chucks for free. Thanks again to all those who commented to me on this. I have to agree that, once I figured out the negative rake problem, the flutes sure were nicely centered. Pete Stanaitis" Well, Thanks to Pete Stanaitis, (who called The Drill Doctor folks thanks to Bob Engelhardt, Pete's post quoted above), I too, called the Drill Doctor company at the above number. My experience was the same, got a nice english speaking human on the first try, who directed me to yet another english speaking human (Imagine that!). I described my problem, (zero or negative relief angles, touchy setup, etc) and the nice lady asked me for the number on the bottom of the machine. I provided that, and she indicated that that they redesigned the chucks since my machine was made, took my name and address and sent out 2 new chucks. Just got them today. An interesting observation/aside is that the return address on the box reads "DAREX/Professional Tool Manufacturing". Anyhow, the design of the cam surfaces is significantly different. I might call them more "pronounced" or something and the angles the relate the 2 camming surfaces are different. Not exactly sure how to describe it, but definatly different. I gave this a quick try on maybe 10 bits of various sizes, and it sure is a huge improvement. The motion wheen turning the chucks in the machine is much more pronounced and "positive" feeling. I have the model 750 Pro, that came with 2 chucks. It seemed that I could get it to work, but not consistantly and not at all on some bits. Set up was very touchey. The new chucks seem to have solved much of that. I had one bit that seemed to have less relief that I usually would expect to see, so after sharpening it, I reset it in the chuck and ground it again. It looked much better that time. Not sure I could explain the reason for that, but it seemed to work. I blew a few holes through some 303 and 304 stainless scraps, they worked really well, cutting 2 nice curley chips. Just my first impression with the new chucks. All standard disclaimers, no connection, just a customer, blah, blah, blah... I do appreciate it when a company stands behind their product like this. I bought this thing maybe 1 1/2 years ago, did not use it alot. When I called, i got no grousing, no 40 minute call to Sri Lanka, no "fax me your sales recipt", no nonsense. Just a nice "I'll send you the new chucks, try them out and if you still have a problem, call me back. Here is my direct number..." How refreshing!! And of course, I appreciate the guys here who take the time to post when they learn something like this. I'd have never called if Pete had not mentioned it on RCM. Thanks, AL A. |
