For serious cutting on big trees I use either a Makita type die grinder or usually a professional big one which is made for professional work. It does not get hot even after hours and it is 1500 Watt, which is quite strong. And it has ADJUSTABLE speed. But it costs around 2 grand all together.

It was mentioned that it is VITAL to know the maximum speed for your bits. Yes, there were incidents with the Samurai because people did not bother about speed restrictions. There were incidents withthe Ninja, which once flew through the audience, at the thick plastic tent wall and right though it like a bullet. Marco Invernizzi used it for the first time at a Gingko Award demo and this tought him a lesson. But this does not say anything against the Samurai, the Ninja and related bits. It says everything against reckless users.

I, as all Tyroelan mountain farmer's sons, have always regarded myslef as invulnerable. Well, I have grown older and have learned to use goggles while working with power tools and I regard them like dangerous weapons. A big Makita type grinder at full speed is like holding a hand grandade in you hand.
