I use my TS75 on hardwood all the time. So far I have been fine using the standard blade that comes with it. The cuts have been very, very good. If I were to rip thicker material like 51 +mm then I would probably opt for the Panther blade -- the cut might be a little rougher, but it would go through the material easier with fewer teeth. I think that the TS75 is a perfect saw for thick hardwoods.
