Most drill bits become dull from trying to hog a hole into metal.Most people think they can get by with drilling only one hole.Bits will last MUCH longer if you start out with a small bit and work up to the size of drill you want. Forcing a bit to do more than it should and drilling at a faster speed that you should creates a lot of heat which removes the temper of the drill cutting edge and then it is all over for that sharpening. Its not always a case of "cheap" drill bits.In fact it almost never is the case. A pilot hole is key to keeping drill bits sharp.

And another tip.Don't just stop at tightening one hole in the Jacobs chuck.Tighten the chuck in all 3 holes.That will keep the drill from spinning in the chuck most times.

2 additional comments that I have learned over the years:

Always use a quality cutting oil.

Hold speed down to a level that will allow the material to show evidence of being cut; i.e. spiral screw shavings or chips and put lots of pressure on the bit (preferably drill press vs hand drill).

Worst thing I did early in life (when they didn't have variable speed) was run the drill at 2000 rpm or whatever it was and use no cutting oil. I could dull a bit in 2 minutes.

Today I don't remember the last time I dulled one.
