I was especially glad to see that this saw was deep enough to make it all the way through the countertop the cheapy allinone hole saw would not have made through and i would have had to go through the bottom of the cabinet

After screwing it down for about 2 turns it got really hard to turn and it was not yet fully seated on the mandrel

When you get through a piece of 2x4 for example the hole saw is filled with the small hole you just cut

You have to get the core piece out before you can drill through another layer of wood

You can use a screw driver and sort of pry it out from the sides using the slits that are cut into the drill

Another way is to unscrew the drill from the quick change mandrel and punch it out from the center using a screwdriver and hammer

If theres any negative with these hole saws its that sometimes when they are new they are difficult to get screwed onto the mandrel the first time

I found that screwing it on a little backing it off and then blowing the paint residue off and going again worked
