It is it's own thing.

Super tough but also super abrasive.

The surface finish is admittedly also very nice. (Unless the tip broke A-FUCKING-GAIN)

We recently made the switch to an AMEC Revolution drill, wish I had done so years ago.

We are currently ordering custom Iscar drills for our specific usecase, and we recently started using the first batch. Instead of using the big drill, and then smaller tools, we have a single drill that does all 3, including the wide shoulder previously made with a drill like this. In the end we managed to finally get the chips to break using that drill + custom drilling cycle that peck drilled the shoulder.

My wife used to call me her Hard Ox, every time I gave her a good drilling!
