Hole Saw. Have a couple of drills. I used the faster drill with more power. Started nice.Even started a pilot hole. But just before it went though the other side of the wood it bound up. Hurt my wrist. Did I push it too hard? Maybe at a slower speed?

Hi,
With a power drill, usually you use a holesaw that has a pilot bit at its center. Drill far enough through the piece until the pilot bit protrudes, remove and proceed to the other side to finish the hole. The pilot bit serves as an excellent locator for this. Finish the hole at reduced speed, if you are using a variable-speed drill; a highly recommended item in this situation.
Peace,

That is a good idea. About finish it from the other side. Thanks
