It means it will fit in a 3/8" chuck - AKA reduced shank.

It's a style of drill with a reduced shank so it will fit common power
drills and presses. Generally, sizes up to 1-1/8" have 1/2" shanks, with
flats on the larger sizes to prevent slipping.

should have said, "1/2" to 1-1/8"

I've seen smaller Silver & Deming bits than 1/2", but they'd only be of use
if you had a 1/4" or 3/8" limit on your chuck.

It means that it has a 1/2 inch shank.

Thanks. I learned something new. Now I gotta watch yard sales and fill in
on my 1/2"+ bit selection. This was $18, and I imagine I'll probably get a
dozen or so at a yard sale for the same money.

But I NEED this to put my boat rollers on, so I just bit the bullet.

The 1/2" shank fits the largest MT2 (or B&S7) collet and permits a
hobby milling machine with limited Z axis travel drill large holes, in
steps. They slip more easily in the chuck or collet than a full-sized
shank. The ones with three lobes don't slip, instead they knock you
around when they grab and remind you to buy a bigger, slower drill.

A Jacobs 36 chuck that will take a 3/4" drill shank is over 3" long
and restricts the height of the work piece on a small mill or lathe.

It's not difficult to add flats to a shank for the drill chuck jaws to seat
securely on.. a rotary tool/Dremel or often a file will effectively cut the
softer drill shank area.

Those are notorious for slipping in the chuck, so if you can find the
S&D's with the 3 flats in the shank, grab them!

That means that it has a reduced shank. I guess that they were
the first to commercially provide such drill bits, and now they are often
sold in sets under that name as a generic instead of a brand name.

S and D with three flats? That's got to be tough to play, on a piano. Key of
