You can see people sharpening drill bits on the internet that have been doing it for 25 years and they make it look easy, but if you are new at it you need to duplicate the angle. Use a piece of solid cardboard use a ruler and draw a straight line. Lay the side of the drill bit on the line. Now draw the angled line at the top intersecting the first line. now use your ruler and make the second line at least 1& 1/2 inches long. Cut out the cardboard and you now have an alignment tool to check your work. It is critical to make the sweeping angle up to the cutting edge on both sides. This is done by rolling the drill bit against the grinding wheel. Given that you are new at it you will need to practice. Use a spray paint can plastic lid with water in it to keep the bit cool-- if it gets too hot then you will have a soft tip. The bit must never get hot enough to sizzle. When you think you having it look like an unshapely bit put it in your card-board angle gauge one last time and mark the chisel point location on the cardboard. now turn the bit half way and check the chisel's point against your mark if it is not correct regrind the short side slightly and check again. If the chisel bit is not in the center then the bit will drill a larger hole. On very small bits you just do the best you can. To see the next post click here
