Machines have been made to sharpen drill bits. In most cases they work, but for the weekender DIY, knowing how to hone up a bit so it cuts doesn't take a rocket scientist to figure out. A drill bit can have two flutes or four flutes or any in between. Four flutes usually is referred to as a core drill with a hollow center.
Look at a drill tip. You'll see a flat area, this is called the web. One of two edges is the leading or cutting edge. The flute that follows is the rake. This rake is tapered at an angle to the cutting edge to provide a path for the cut metal to follow out of the work. Feed pressure should be constant to keep intimate contact with the work to remove metal and keep the edge cutting.
