18v Cordless Drills

- Converting 18v Cordless drill to Corded drill, what power supply to use?
It's a cheap Black and Decker cordless drill, 18v. I would like to know what voltage tolerance it has(can I use a 15v power supply, how about a 24volt power supply?) and would like to know typically how many amps these cordless drills use under full load. the Batteries are shot basically, and I can't find a corded drill with the cordless features(torque settings etc.) so I wish to utilize these drills I have laying around, I was looking in catalogs and seems to me a good power supply I can find is a 15v with 10 amps continuous or a 24 power supply. I hooked the drill up to my ex-tech variable voltage 3amp 0-30v power supply, my current limiter would keep tripping and can only screw a deck screw in about half way.... What would be a good power supply for this application, and I can't seem to find the watts the tool draws, so I am not sure how big of a supply I need, or the voltage.

A The more voltage the faster the drill will spin until it destroys from wiring flying off the rotor. At 18V it probably draws about 10 Amps at stalled condition, maybe more. If you keep it at 10A for too long it will get too hot and destroy from overheating. The faster the motor spins, the more airflow = more cooling. Drills (electric motors) don’t like low speed high torque. Air tools get fresh air to cool even when stalled. Heating is proportional to torque. Hope this properly answers your question Guru

- I found a cordless drill and i need a charger do i need to get a specific one to the drill or to the Battery ?
I found a Tooltec 18v cordless hammer drill but no charger are there specific types of charger to types of batterey or is it to the drill itself can i use the charger from any drill with an 18v removable power pack or the battereys unique to the drill itself or are they all a standard fitting and where can i get one?

A sorry mate. each cordless comes with its own version of charger. batteries in some cases are inter changeable.admittedly not very often. check out the local tool mart and see how much a charger is. if its more than £e30.oo , stuff it . tooltec sounds like ,no torque,no gears worth speaking off. if you can t get the charger and a spare battery for under a tenner,forget it .waste of money. invest in a makita. i ve worked with makita for 25 years, and they are the most reliable easy to use ,hard wearing tools around . think about it. ps b & q has a great offer for a 18 volt cordless makita ,inclusive 3 batteries and charger. batteries charge in half an hour . it will set you back £90.00.
