How to Calculate Torque for Drilling?

[RookieLearnin]

Hi!
Gonna keep it short.
Can someone give me an information how to calculate the needed torque/power of a drill?
My guess what would be important to calculate this is the density of the material that's being drilled, the depth of the drilling, and the diameter of the drill? Right? But i just can't find any information how to do this.

Thx for any help u can give me.

The torque of the drill is independent of the material it is drilling into. The "torque required" to drill something does depend on the material and the size of the drill bit.

The http://en.wikipedia.org/wiki/Torque" has good explanations of torque and the calculations you will need.
