I have an Olson 6 t/d spreader blade that works better than this blade but I wanted more t/d for a smoother cut. This Powertec blade does not appear to be of the same quality as the Olson blade and a 25 year old Delta 14 inch saw with Powertec blade vibrates severely. The Powertec blade had a slight crease which I corrected slightly by bending the blade with my fingers, which is not possible with the Olson blade which is like spring steel. The Powertec blade works straight and leaves a flawless finish since it's 18 tpi, so I'll leave it where needed for these specific cuts. But I put the Olson 6dpi saw blade back in for general use because it makes the saw run very smoothly and quietly. If I could find a 10 or 14 dpi Olson blade I would prefer this Powertec.
