Mini Electric Drill Kit

I used it to make a mini drill press that I saw on YouTube for holes to drill in thick circuit board for tube amplifiers, and it works great. I use one of those 12 volt motorcycle batteries to run it. The lead-acid type that can be recharged with a laptop charger and 21 watt car light bulb as a current limiter.

When I saw this on Amazon for tad over$10, I just had to buy it. I was thinking about making my own mini drill press - because I like to do things like that. Note that you can also buy a similar motor, or a similar JT0 chuck package (without the drill bits) separately for just under $10 each.Now I am extremely pleased with what I received! When I assembled and tested everything using my bench power supply, using a PWM motor control, it simply worked much better than I expected. There was no apparent offset or wobble of a sub-mm drill bit in the chuck at any motor speed!The only issue I noted was a slight grind when turning the Jacob chuck to open and close it. That's why I gave it a 4 star, instead of a 5 star, review. This is something I could have easily ignored and live with. However, it prompted me to do something that I'd never done before, but always wanted to do - disassemble a Jacobs chuck to see how it worked! I also wanted to see if I could fix the grinding problem (there are some Youtube videos on how to do this). I soaked and cleaned the chuck parts in some isopropyl alcohol and inspected them carefully. I noticed one very tiny metal splinter and two somewhat and two somewhat microscopic dots that washed out. After cleaning off the parts I lubricated and reassembled the chuck and pressed everything back together in my bench vise.Now the Jacobs chuck opens and closes very easily, and it still runs true on the drill motor.

--I've been using them to make 3D printed drill presses and other benchtop tools. The chuck adapters work great too.

Pretty good for the money, I built a little to start tool with mine. Keep in mind the shaft is very narrow about 2mm if you use it in a similar fashion( which I imagine everyone will) you need additional support because the simple action of using the chuck to tighten the jaws will bend the motor armature

This is the handiest darn tool I think I've ever had. While my Dremel is mounted in a press for PCB drilling I keep this one at my work bench for touch up work on the PCBs. Just have it running on 12V from a lab power supply. I also like the key for tightning the bit. The Dremel has a twist type collet which you really need a wrench for to get the bit tight but the key works better.

This is a fantastic motor, I suggest 2 or more amps.

This is a very nice simple 12v electric motor drill kitLIKES:1. SIMPLE kit...GREAT FOR DIY2. INCLUDED NEEDED ACCESSORIES such as the INCLUDED DRILL CHUCK3. SIMPLE to set up and FUNCTIONS GREATDISLIKES:1. Product does NOT INCLUDE a On/Off switch and it would be nice if this kit had a way to adjust the rpm speed for this Electric Drill Motor within the kit

Great for trying to drill in very tight spots like inside of speaker boxes
