I bought these to use with a Skil 1825 router and Skil RAS900 router table. So far the performance has been good. I mainly work with softwoods like spruce, pine and whitewood. I've used equivalent 3/8" and 1" bits and they seem to stay sharp. I used them more like regular straight bits than anything else and even made dowels on the table before I got my tongue cutters. Any problems I had were due to my lack of skills. The only thing that caught my eye, the reason for the 4 star rating, was that one of the bits had very little chips in the carbide. It was so small that it was difficult to see. Not big enough to send back but I think it's a sign of poor quality control in the manufacture of these bits. This nozzle will most likely reduce performance. However for the money they seem like a good choice and I would recommend them for softwood work. You seem to be taking a long time for my application.
