This nozzle works as advertised. I use it on Porter Cable 690 on Oak. I do 4 passes to reduce heat and chip/tear. I've molded a few parts with it so far with no problems. The bit stays sharp without discoloration. I recommend this cutter to cabinet makers looking for a drawer cutter that delivers a clean cut. I wasn't familiar with whiteside beats at first, but this one seems to work well. I will continue to use it for other projects and wood and report back on performance later.
