Hi friends, I got this Hand PCB driller from shop no 718 Old lajpat rai market for Rs.1050. This is a cheap chinese driller. Although it is not for PCB drilling exactly, it is meant for some jewellery work but it had some PCB drill size adaptors so I purchased it. Unfortunately when purchasing I didn’t saw that it has adaptors only upto a size of 1mm drill bit and that a very poorly built adaptor.The drill bit wiggles a lot when running the machine and is not the best. Now I am regreting purchasing this bastard drill machine. I do not recommend anyone to buy these cheap chinese machines. Only buy good branded machines from venders like Black and Decker,etc.

Help me finding the specification of this DC motor
Hi friends,I got this motor for Rs.150 from Old Lajpat Rai market,Delhi. I searched on the internet and it is supposed to be a printer carriage motor. Unfortunately,I was unable to get the exact specification of this motor. I ran this motor on my 5 A DC power supply at about 26 Volts and it is consuming about 20 mA at no load. Also the speed and torque of the motor is not that great as I tried to stop the shaft with my hands. Please,if anybody of you know the exact specification of this motor, then let me know.
Thanks.
