Last night I used a solid carbide 90° to mill a slot into the top of a large octagonal BAT 'M' action. I want to be able to remove the scope base and desired a solid keyed locking surface...... I wanted a 1/4Wx1/8D slot in which to epoxy a key..... I used a 1/4" drill bit for the key. I tried small ball endmills and flat end mills.... In the end I milled the slot using a 1/2" diameter solid carbide tool with a wicked sharp 90° tip. It's designated as MCH-4D.
And of course it knocked the tip off.
My question is, is there a bit, a grind that will cut a decent 1/4x1/4 slot? I'm picturing a bit like a 3/16" center drill with side-cutting capability
I have keyway stuff, I'm looking for ease of setup
