Avoid Breaking Pilot Bits For Hole-Saws

Thanks @TomC for this great idea!

Yes, I needed to make a hole for pipe to enter my tank at a tangent, so drilled the pilot hole with a regular 1/4" bit and put a longer piece of 1/4 rod into the hole saw to let me enter at a long angle. then continued to use this setup once I broke all my center drills with grabbing.
