Review: Better than the Saburr Tooth - I am genuinely surprised at the quality of this tool. I used it to grind out the hollow part of a spoon and it worked wonderfully. I did 2 spoons from the same maple board. One board I used the Saburr Tooth sphere coarse and the other I used this Kutzall coarse. I thought based on looks that the Saburr Tooth would do the better job, but actually the Kutzall performed better, both in the speed of material removal and ease of handling. I thought the Kutzall would clog with wood and require cleaning every few minutes, but the opposite was true, it never clogged. The Kutzall actually ground out the wood and it came out in a fine dust, while the Saburr Tooth cut out much larger pieces, but at a slower removal rate. The wood heats up with the Kutzall, but it doesn't burn, at least if you keep the tool moving. I also got the fin Kutzall for clean up and it works well too, just not as profoundly as the coarse Kutzall, which is to be expected. I'm glad I got these tools and wish now that I hadn't got the Saburr Tooth tools. I have a dedusting system and work with the project piece with the Foredom rotary tool right at a point of dedusting suction. I generate a lot of the dust and most of it is captured by the dedusting system, but not all, so be sure to wear a dust mask as well.
Review: It works great - Good price
