Don't try to get too carried away with small increments in drill diameter as you try to make a big hole. Stick with a small pilot hole to guide the large bit. If you try to slowly work a hole larger with drill bits, all you are doing is using the outer ends of the cutting surface causing concentrated heat, and dulling only the edges rather than allowing the entire bit to do the cutting and carry away heat as a whole. So next time around you use it you get an uneven cut with that drill and egg your hole, or find it just doesn't drill worth a darn.
