It's pretty neat, isn't it? The method has been around for a long time.

I wonder how well that would work in wood with the right bit and speed.

When I read the title of this thread I thought someone wanted some help with sharpening drills, how wrong and impressed I was.

Yes Dave, I too am wondering if it will cut wood, someone out there will know.

I spoke with my brother who is a machinist by training and sells huge machines now. He's familiar with these cutters. He said they'd work but leave a fair amount of tear out especially in stringy wood like oak. I imagine, though, if the cutting edge was ground properly and the speed was right, it might do a nice job.

Roy Underhill demonstrated one on an episode of the Woodwrights shop, but I cant find the episode ?, the 'tech' has indeed been around for a long time, it works on the 'reuleaux principle' (oooh, cheese baguettes)

Sometimes drilling a hole in steel with a large drill [two flute] the tip will try to drill a triangular hole in a similar way until it it's fully in.
