One time, long ago, someone posted a link to a hole saw bit that was for making a hole bigger. Instead of using a drill bit for the pilot, it used the original sized hole saw for the pilot. So it was a hole saw inside a hole saw.
Anyone know where to find one of these?

If your just drilling through framing (not finish work), you can drill the larger size hole through a scrap piece of lumber and then screw or clamp this piece over your existing hole to use as a guide.
1/2" or 5/8" plywood is ideal because you can easily screw through it to secure to the lumber that has the hole that needs to be enlarged.

Hi,
My DeWalt and Lennox hole saw sets allow nesting a smaller cutter inside a larger one on the same arbor.

Except y’all missed SB’s own part about finish work. The reason this came up this morning is because of a new customs cabinet. And I don’t see why the size of the pilot would make the holesaw any worse grab.

The size of the "pilot" would matter because the person wielding the drill might not have the skill to drive the smaller hole saw in without binding. On October 11, 2017 at 12:12, 3PedalMINI said...

My take: he has a cabinet with a wire pass through hole from the factory or previous installer; it’s too small of a hole, he wants it bigger to get more cables through.
My idea: have some monkey hold a board on the opposite side than you are drilling. This will give your pilot drill bit something to bite into while the hole saw starts to do its thing.

Straight three-prong plugs require a 1 1/8" hole (IIRC), but if you cut a 1 1/8" hole and then someone runs a couple of cables through the hole, you'll have to unwire the entire system to remove that power cord. So cut 2" holes. Then if those holes need to be enlarged, I push the pilot bit against the side of the hole and take a bit more wood out of one side of the hole. My idea: have some monkey hold a board on the opposite side than you are drilling. This will give your pilot drill bit something to bite into while the hole saw starts to do its thing. You'll need an especially long pilot bit for that, but sure. The other approaches don't require anything special.

77W!!! Thank you!!! I am buying one of those Bosch units now just so next time this comes up I am prepared!!! I learned how to use bimetal hole saws back in '82 cutting 5" holes in late 70's Camaros/Firebirds doors through triple steel, spot welds and all! Using a Black and Decker 1/2 hp drill with a big T handle at 700 rpms! I was taught to lock in using your legs and dont f'n let go. Dont force it, just let the saw cut as you ease it through... Slow and steady!!! I actually snapped off the threaded end of the chuck in the armature shaft after years of use. You either got hurt or learned real fast how to use hole saws.
