Chucks for mini drill tools

 Author:   Posted on:    No comments
Miniature drill tools are a must have for everyone who is making his own printed circuit boards (PCB) at home. Not limited to this, drill tools have many uses as rotary tools. Although the motors you will use for DIY tools have smaller power than a Dremel tool, some of the accessories can be used for small work. You can attach cutting discs, sanding, grinding, carving and polishing attachments. What works and what doesn’t depends on the motor you use, the type of drill chuck and the material you are using it on.

Building your own miniature rotary tool is usually cheaper than buying a Dremel tool. If you want something for PCB drilling only, the motor can be very small. And small motors are found in a lot of devices (do not expect to use a motor from a CD/DVD drive for this purpose, but motors from toys, old cassette players, hair dryers, printers, scanners etc. can drill a hole through a PCB). If you are lucky enough to have a motor from battery operated vacuum cleaner or drill machine (like the 775 motor), you can build something very powerful.
