    60* TCMT Dovetail Cutter

    This is the first cutter I've ever made and while there's certainly room for improvement, it does function properly and has already modified many free hardened steel KDK tool holders to fit my CXA tool post. I used a TCMT 432 rather than an insert with more relief angle only because a friend had given quite a few of them. The downside to this was in order to achieve adequate clearance w/o grinding more into the inserts I had to push the cutting edge slightly in front of the center line of the cutter. To my knowledge (which is very limited so feel free to educate me) the only disadvantage of doing this is that the cutter has more of a negative rake so it needs more horsepower to run it. Luckily I have a 4HP Series II BP
    It seems to leave a good finish though it does seem to hit pretty hard even with two cutting edges. Let me know what you think. Click image for larger version.
