I went through a bunch of several name brands that all stripped the threads on that screw-in arbor. I finally removed the pins from one and put bolts through and tightened well.
These were 4-1/4" saws.
good vid,, i worked in the machine shop at a plant that made tilted gravel shaker units,we made the sides from 3/8-3/4 plate,, we clamped them together and tack welded them..then used starett hole saws ,, we never drilled a chip hole in the side,,most chips came out in long strings, we just pulled out the hole saw,an blew out any remaing chips and kept on sawing,,ran the radial arm drill press lowest it would go 60 RPM.. i think,,good vid but it ran over 10 min and u did not mention your RPM u ran at, so heres your Sam Kinison award,,,OOOOOH,OH,OOH,OOH,OOOOOH,OOH,OOH ,OOOOOH !!!!!
Hate to burst someone’s bubble but this short cut has been around for a long time.
That's an excellent tip that many of us have never seen before! Just ignore the toxic negative comments.
While I agree the tip has been around for a long time, it doesn't hurt to be reminded of useful tips from time to time either.
I also stand with previous comments about the importance of using low RPMs.
I will also add that using a lubricating coolant when ever feasible is equally as important as the low RPMs especially for increasing the longevity to the cutters.
As far as being brand agnostic goes we might as well be as probably many of the name brand cutters are most likely made by 2 or 3 manufactures and privately labeled
Having said that whenever possible I do prefer to buy hole saws with brand names after band saw blades instead of power tool names, which may or may not be any better or any different than the power tool names as well.
Thanks for this great tip. As far as I am concerned, this one tip justifies the annual subscription fee.
Thanks for this one. I have been working steel for many years and did not know this tip.
