Here's a picture of what your drill chips will look like if you get the
feed and speed correct. Once the chips get to be a bit longer than the
length of the drill bit, you should stop advancing the bit so that the chip
will be broken, and you can put a bit more cutting fluid in the hole.
With the chips like this, you don't need to back out the drill bit to clear
the chips. In this picture I let the chips get a bit longer, but you need
to be careful because these are whipping around at the same speed as the
drill bit and they're sharp!
