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 drills 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

If you have a 38 drill shank the 12 will not fit

Amazon promised delivery in 2 days but i thought they must have forgotten to consider the different time zones
