I bought this product for a PVC project and chose SMT because of the low price. This Forstner is far from the quality typical of CMT products, I even doubt it's genuine. Terrible grind quality! It worked for my project but I would never dare use it on quality wood. AND THIS IS AN 18MM BIT! Not 23/32 as advertised. 18mm.7086”, 23/32.7188”. I hope CMT didn't go that far.
