Some time ago I found a page or two about bow/pump drill, and in particular about the bits and various profiles.

I’m having trouble finding anything now.

Is there a name for these non fluted bidirectional bits?

Anyone got a some links detailing various profiles?

Seems to be quite a few if you search Google under “bow drill and bits) using “Images”

It’s probably the best site out there. Lots of different primitive skills forums. ............. Jerry (in Tucson)

Just to clarify, I don’t mean primitive as in stone & bone bits.

I mean steel bits that don’t have flutes. Just a shank with a sharpened working end.

I thought I had seen a name other than drill bit being used. Perhaps by someone using a hand drill, just a stick with a metal bit.

Are you talking about spoon bits?

Also, Yankee style push drills have birectional bits without a spiral. Not sure what they are called. Maybe push drill points?

There are a few different types. I remember seeing an old plated brace that a couple of each, including the spoon, spade, and some other one I forgot what was called. Gra mercy does make new spade bits that are good for chair making:

Bidirectional bits
Pin
Shell – probably most common, looks like a pointy gounge, only cuts well at 90 degrees
Spoon

Will work, but designed for single direction
Nose
Centre/batwing

That’s right, shell bits are the ones that I usually see with old plated braces. Not to be confused with the actual shells the romans used.

Have your say...
