The form-relieved design is a lifesaver—I've been able to resharpen this end mill twice already without losing the radius profile. It cleaned up the sharp edges on a batch of steel brackets perfectly, saving me from having to hand-file each one.

Used this to round the edges on some aluminum brackets and it cut clean with no chatter. After a few sharpenings the radius is still exactly the same, which is the whole point of the form-relieved design.

The form-relieved grind is the real selling point here — I've sharpened it twice on my bench grinder and the radius profile hasn't budged. Cuts clean 1/4" rounds in mild steel with no chatter. Exactly what I needed for my bracket edges.
