How do you decrease rpm of the drill so that it draws less current from 4Amp to 1 Amp I want it to run very slowly?

It sounds like you need a variable speed drill. There was an item on the market a few years ago that you could plug your drill into and control its speed. I haven't seen one lately since most new drills have variable speed built into the drill. On a drill press all you need to do is move the drive belt to the smallest pulley on the motor and the biggest pulley on the drill spindle.

How do you make hole drilling where at the exit the drill has partial entry in to the wall thickness which makes the load nonuniform on the drill and hence drill breaks and size is not maintained?
There are a few ways of doing it depending on the exact geometry, size, and tolerance. You could drill the hole before cutting the profile that results in the partial entry. You could drill very carefully and slowly, stepping up the drill from a small size to the final size, if the smaller size would enter complete. You could make a fixture to fit over the part so the drill is guided into it. There are low melting alloys you can pour around the area to make a complete entry. You then melt the alloy away.

A power drill runs at a voltage of 120 V and draws a current of 4 A. What is the wattage of the drill?
The formula you are looking for is W = A x V. Watts = Amps x Volts.

How many watts of power does does an electric drill use when it is plugged into 120 volts and draws 10 amps?
Power = Volts * current [p = E*I]; 120volts*10amps = 1200watts
How do you drill a cast iron sink?

What drill bit is best suited to drill into lead?
Use a brand-new bit for metal mounted on a hand drill (not electric). Slowly rotate the bit in the lead, which is a "soft" metal.

What drill bit do you use to drill holes in perspex?
You can use a standard HSS drill bit with the edge slightly dulled with a grinder so it does not 'break through' at the outside edge. -Drill slowly and hold the drill steady. I always put a piece of smooth scrap wood at the point where the drill bit is going to come out.
How can you drill a hole in a china plate?
Very slowly with a Carbide drill bit or Diamond core bit, both will work, but the diamond core bit works much better, make sure the bit has a constant flow of coolant or be submerged in the coolant. (go very slowly, do not apply much pressure, let the bit do the cutting) The best way is to use a drill press but a hand drill will work.
How do you cut or drill through a fixed wall mirror to mount a light fixture?
i think you should drill through the wall slowly The question was about drilling an hole in a mirror. I think the correct way to do this is to mark out where the hole is required, get some putty and form a cupped mound below, fill with varsol or white spirit, and drill the hole slowly with a special glass drill bit. You must keep the bit lubricated with the liquid to dissipate heat and prevent the mirror from cracking.
What drill bit is used to drill holes in gemstones such as quartz agate or green tourmaline?
A hollow diamond drill bit, with lots of water, cutting slowly, will do the job. Ideally in a drill press of some kind instead of freehand. Diamond bits in rotary tools like Foredom or Dremel may do it, if it's suitable to use them with lots of water.
