Review: Excellent option for the money - New to slab flattening. I made the mistake of purchasing a cheap 15 bit at first. I wasnt pleased with it at all. But this bit is awesome. It flattened walnut like butter. I ran 4x slabs thru it back to back. Towards the end I think it got a little hot but it performed well. Its worth the money to buy this bit. Very happy.
Review: It works perfectly - It is super sharp. It had no problem cutting cherry, hard maple, walnut, and Purple Heart. It cut so smoothly you almost don’t have to sand it. I did learn that it is best to move your router in 1 direction to avoid chatter. Make sure your jig is dead flat and the carriage perfectly parallel to the jig.
