Animal, I guess I just try to push my cutting to hard. I have dulled my Warners cutters many times. The front corner actually get worn down so not as easy to sharpen as just doing the top. These inserts do work well but the lack of a chip breaker is a small problem. They will custom grind them with a breaker but don't know the additional cost. Carbide just lasts longer for me. I just get to impatient I guess.
