Testing 20mm carbide end mills against AR steel. It sorta works.
Per your requests I made laptop/hardhat sized DANGER! stickers: https://www.etsy.com/ca/listing/746553214/hardhatlaptop-decals

I use a hanita when I cut this stuff. Was able to cut .625 Depth .15 radial. I think around 2,000 rpm at 19 ipm. Run alot of ar400 2300 rpm around 28 ipm same depth .25 radial. Ghuring diver endmill works great on the stuff to.
How did the surface hold up as a Target against 5.56 rounds? Did it pit? What distance were you shooting from? I found that ar500 pits at 7 yds with 5.56
Might to find and ask Iscar Rick for the feeds and speeds… he knows all that stuff off the top of his head
Wow rape that drill
Wow you tape that thing
I am dying 🤣🤣🤣🤣
"there's a lot of buttons here what'll put a fuck right in your week" has been the story of my life since i started cnc machining
I remember one of the guys once was blowing off chips off the keyboard of our CNC with an air hose and fucked some shit right up. XD
As someone who isn't a machinist. Could part of the problem be the way you rigged that L-shaped piece of stock out? The heavy end L-shaped end hanging out? I know you had something underneath it but, with the good review you gave the bit prior to filming this cut, and the way that the bit seemed to crack/break towards the end of the cut repeatedly. Wouldn't that indicate a possible slight vibration cause the bit to fail? Or was that the intention the entire time?
Cutting hard steel with end-mills has been troublesome for me. I switched to insert milling and never been happier.
Sure, those things don't last as long, but at least they're VERY consistent. I also use a Kolroy system that has part A and B for roughing so, part A will cut a certain height and B on another, Both blades are on the same APMKT insert, so you just have to buy one set.
I dieddd at "add text" 😂
Nobody can be this canadian
Love our probe on our Haas. Only broke two of them so far
My fathers workplace runs Hardox 450 on a old russian lathe. They described it as "You basically just have to crash the machine into it for every cut, and hope for the right things to break"
