How to Make Powerful PCB Drill Drilling Machine at Home

Hi,Its very easy to make a PCB drill machine.the drill bit and the metal shaft is available in hardware shop and you can collect the mini motor from a old tape recorder,and the switch from a CD player.If you are ready to spend more,you can replace the normal DC motor to a brush less DC motor(BLDC),that is more powerful.And if you want to control the speed pleas use a speed controller circuit( better to use PWM speed controller circuit),.various circuit diagrams are available in the internet.
