Mistake! I had a dovetail bit in a router table, which you cannot take progressive cuts with, break at end of the cutting edge. Scary, but uneventful. It was contained by the material and the diameter was small But, after I had a second round-over bit shatter, I pitched the set. During handheld router use, a bearing based edge bit is more dangerous because often it is cutting between the user and the edge of the material. When it fails, the material will prevent it from projecting away from the user. The additional mass, diameter and 15,000+ RPM make them dangerous projectiles. In my case, I was making progressively deeper cuts. Fortunately, when it failed, I was using a dust collection shroud that contained the bit. A habit I do not always follow. In the dovetail bits failure, there was a visible material porosity flaw inside the shank. I believe the round-over bit failure was a combination of poor balance and inferior materials. The bits were factory sharp and failed after minimum initial use. Remember, as a bit dulls, it builds up additional heat and required more power to cut through the material. I flying router bit doesn't make a clean flesh cut. Should one decide to purchase these bits, for safety's sake, get 1/2" shanks, keep the RPMs to a minimum, take progressive cuts, use a shroud or something to contain the bits, keep them sharp and finally, if it seems unbalanced, do not use it.
