We’d like to let you in on a secret we learned from the plumber a while back: it’s not necessary to break your back when using hole saws. Milwaukee makes a slick set of “selfeed” bits that, well, feed themselves. (Now if only we could do that.)
These bits essentially have a screw mounted in the center. To use them, you simply act as if you’re driving a screw. The screw grabs the wood and pulls the larger bit right on through. Also, whereas hole saws fill up with the wood you’re cutting — they’re shaped like a cup, so once the “plug” you’re cutting out fills the bit, you’re in trouble — the Milwaukee Selfeeds actually chop up the center wood and eject it out the back.
The result: It’s easy to line up, easy to get started, easy to keep straight as it cuts, and it’ll cut through very thick material without problems. Nice.
Street pricing starts around $25.
