    I had a good pneumatic rt. angle drill that somehow went on walkabout. I need to replace it. What are the brands to avoid and what are the best? What rpm is the overall best?

    Thanks to the experts

    I am by no means an expert, but I would think the RPM would depend on the type of material being drilled along with the size and type of drill bit.

    Boeing prints a drill guide for its employees for such a large spread of materials and diameters that I'm still "spun"

    I have such a drill motor. Take what you can get. If I wanted to fix Boeing's criteria I'd need a 7000 rpm drill motor.

    Find an older Dotco with the speed you need. When I moved out of production, the 2 Dotcos that I had in my tool box, were probably 15 years old and ran perfect. I was not the first guy that had them in the plant, and not the last by far.

    What is the 1/4-28 thread reference for?

    I had an electric right angle drill that vanished (more likely it's packed away somewhere and I can't find it) and if I recall it had a 1/4" chuck.

    The drill I'm referring to does not have the normal chuck but instead has a female ¼-28 threaded hole. The drill uses bits that have a ¼-28 stud on one end. For really close quarter drilling they are the "Cat's Meow".

    Do you recall if it was fixed or variable speed?

    Stuart: All of ours were variable speed. One of mine had a top rpm of 3-3500 or so and the other was around 2500 rpm. I typically was running drills between a #50 up to a #20, and occasionally reamers up to a .204" with them.

    Gave up search and bought one from A/C Spruce. Variable speed but it is going to be uncomfortable in my bed every night. $300 drill is not going to grow legs.

    That's not bad price wise at all Stuart. A new Dotco will set you back about 3-4 times that......

    $300 for an angle drill is cheap. It cost me that to get the head on my Dotco fixed after I managed to strip the gears in it.

    Well it happened again. I got delivery of my $300 rt. angle air drill from A/C Spruce, went to my threaded drill locker to select a drill, and the first thing I see is my old drill that had gone "walkabout". The best way I know to find a lost tool is to buy a replacement. Since I had looked there several times before deciding to buy a replacement, and I have been listening to a Harry Potter thing on the car radio, I now know that someone put an "Invisibility" curse on my Drill and it finally wore off!!

    Don't decode BTDT Probably closer would be BEDS (bad eyes dumb ****) Another: CFFTIJLD Can't find F(in) Tool I Just Laid Down. I've never misplaced the piano after a short spell of using it. Maybe there is a message here for me.

    Guess what? My lost drill that had just hidden under an invisibility cloak until I bought a cheaper replacement turns out to be a Dotco.

    Obviously, you prefer the new drill, so just send that old Dotco to me.

    Thank you.

    Obvious? Obvious? I sure don't know where you got that one. There is room in my bed for both drills. I've also started a search for anti-invisibility cloak spells. So far Harry Potter isn't answering any of my emails. Also I can't afford the armed guard that would be needed to ship you the old Dotco.
