Strictly talking tapered square shank brace bits … how many kinds are there?

I love looking for brace bits that I do not yet have.

I have twist bits, spade, batwing, auger, and the “normal” expansive bits (e.g., Irwin—including micro-dial).

What I do not have yet is a circle washer cutter, 3-jaw chuck (yes, they make a 3-jaw chuck with a square shank on the back end to go into your 2-jaw chuck), and a few different kinds of Bruno brand expansive bits (which look like a fly cutter and use a single-point cutter like you might use on a metal lathe—this one fascinates me and you can get it in twist pilot or snail pilot).

Then there are counter-sinks, spoons, gimlets, and reamers.

Square-head screw, flat-head, and slotted-head screw drivers.

Extensions and depth stops too (the latter, which I can’t for the life of me figure out how it works from looking at pictures online).

But am I missing any bits?

I do love maximizing my Galoot Index on projects lately, and I am learning how to use my grandfather’s brace.

I would love to find square tapered Forstner bits, but from what I can tell they appear to be impossible to find.

I know they existed though … as here is an advertisement from 1927 for them, not only mentioning them but sporting a picture of one.

I have searched and searched and searched but cannot find ANY square shank Forstner bits.

The text in the 1927 Ad reads:


“Forstner” Brace and Machine Bits

For Fine Carpenter, Cabinet, and Pattern Work

SPECIALLY ADAPTED FOR HARDWOOD WORKING

The Forstner Labor Saving Auger Bit, unlike other bits, is
guided by its Circular Rim instead of its center; consequently it
will bore any arc of a circle and can be guided in any direction re-
gardless of grain or knots, leaving a true polished surface. It is
preferable and more expeditious than chisel, gouge, scrool-saw,
or lathe tool combined, for core-boxes, fine and delicate patterns,
veneers, screen work, scalloping, fancy scroll twist columns,
newels, ribbon moulding and mortising, etc.

Manufactured by THE PROGRESSIVE MFG CO., Dept. “A,” Torrington, Conn.

Yes, I had to look up what a “newel” is …


the central supporting pillar of a spiral or winding staircase

On regular staircases in modern construction they are also called newell posts, then the ballusters are the smaller ones.

I have expansive bits (Irwins) So-call center bits ( single spur, LARGE center point) a few twist drill bits with the tapered square tang..a couple countersink bits…and a few screwdriver bits…and about 50 auger bits…

I do not have any spoon bits, though…..

Not sure IF a chain drill attachment could be considered a “Bit”....mine is by Goodell Pratt Co.

There is also a 12” long extension…with a chuck on the end.

Batwing bits are also known as center point brace bits

I saw more than one of those on eBay and wasn’t sure what to think of it. It has a square shank for a brace bit but … turns a chain? or is turned by the chain which is driven by some other means?

Is it used for turning your brace into a crank?

I have a hollow auger that I use with a brace. Also a spoke pointer.

There are also different auger bits for hard and soft woods. The lead screw is pitched differently between the two types.

Yep. They’re different model numbers in some drill sets. Someone mentioned it in the vintage drills of your dreams thread fairly recently. If you buy new auger bits today, you almost certainly get softwood lead screws, unless you buy the Fisch bits from TFWW or other premium bits. Most auger bits today are sold for electricians putting holes through tubafors.

While building the drawers for my boring tools till, I covered the bits I have, beginning with entry 16. Really should finish gluing on the last five drawer fronts and get the pulls on one of these days. The Gramercy Spoon Bits are very nice, BTW.

You’ve got a fair few different types of auger bit as well
Jennings, Irwin, L’Hommedieu, lewis for the twisty bit
Jennings, Gedge, scotch, bullnose for the pointy bit.

I’ve probably missed some.

Not sure if the batwings with a lead screw have a different name than the ones without.
