Key Hole mills are awesome. I should have gotten one years ago.

Key Hole mills are awesome. I should have gotten one years ago.

I got one recently. Not used it yet. Did you have any difficulties? Slow plunge then move along then back again before moving up?

Nope. Popped it in the collet and made a macro.

Boom, No mounting hardware.

Nice. Will give that a go thanks!

They really are great! I actually used my drill press before my CNC!

interesting… i guess i need to learn about macros!

Can you give some details or pictures on the actual bit? I’ve been interested in doing this but not sure what bit to get or where to get it

@Munsell_Randall I just posted a picture of the keyhole bit.

noob (ish) here, how do I make a macro for repeatable operations like that?
