Something I would like to pass on. I had to drill some 2" holes
thru the winch mount push bar assy on my Crawler/Jeep/Truck/thingy and
nearly took my arm off when the drill bit mounted in the hole saw
broke. Not smart enough to evaluate the cause I replaced the
drill bit and broke another within seconds. It is important that
the locating piece of the hole saw be round smooth material, the shank
of the drill or as I do now a smooth mandrel, not the flutes of a drill
bit. The flutes will catch then bind and break leaving the hole
saw running amuck.
