Perfectly useful. You leave it by the machine for whacking visitors who don't keep their fingers in their pockets.

As Maxwell Samrt would say when I was young...."Thats the second largest Drill Bit Ive ever seen..."

And now BACK to the NORMAL dimensions of arbors and their drills...

I recently got this from someone who thought that a CNC hobbyist could use this ... ;D

Edit: I realize now that I did not put a slider along my foot. I can be only a few mm's .... ;)

Mine has 10 teeth with a 5.2mm dia, 3d printed using PLA

lol.. ok, ok....

  Those two are so close we need measurments to judge that. Thye look nearly identical in diameter..
so Id suggest the higher tooth count wins.. that means it has thinner teeth.

  ( What a great world when you get to the point we can actually make such things at all..)

Sorry guys I have to disagree, its a question of honor and all that, but mine is smaller! and I do not have big "pinkies"

lol.. yes, big fingers could make it look very small. :)

  But Id say "in a working clock" trumps the bevel requirement, you still win. :)

Completely wrong Art....

The gear is [i][b]-not-[/b][/i] that small, but John's fingers are rather heavy ...  ;)
