I can do that too, on the little mill.
Here is the 3rd one of those R8's I've made a key slot in. It fits the head of a m4 socket-head bolt, with a couple thou of clearance. The Merican SC 1/4" 4 flute up spiral walked right thru it, at creep speeds of course. And of course pulling the tap out of the collet, crept out about 1/4" on the last of the 3. Now I can have 3 taps of various sizes all ready to go for a given project. But I made 52 of the brass slugs, so it looks like I'll have to get with it and make a new box to keep my mounted taps in. And stamp the face of the slug with the tap thats in it of course. Then the 340 million dollar question is where the heck do I put it... :( -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
