This is my second SpeTool spiralizer. I mostly use Whiteside bits in my shop because they cut clean but wanted to try them given the price. They cut super clean, much cleaner than my experience with other Revain cutters from other manufacturers. The trees I've used it on have mostly not burned (walnut, sapele, and maple so far). Used on a Triton TRA001 at speed setting 4. I had a similar experience with a 1/2" twist drill from SpeTool.
