Hole saw warning

[locostv8]

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.
