Yep. There are lots of ways to view it. Both options are great. I just don’t think one is more cost effective than the other. I can just turn one carbide segment if it gets chipped, Tersa is a quicker wholesale swap."

Now that you've come round to realizing Tersa is a quicker swap-? it should make what I said earlier (or tried to) about Tersa being? cheaper the more you change your cutters pretty obvious. Your cutter edge savings with segments is pretty quickly eroded the more you swap edges because of the time suck involved in rotating an entire heads' worth of them.

And you don't have an option for questionable material with segments.? You run it and deal with the consequences.?

Yes, both are great options.? But I still stand my my original supposition that Tersa will be better /cheaper if you are in a production environment and frequently changing blades.?? Turning "one segment" is not where you're losing money.

? It's the turning of 50 to 100 of them !? The more often that occurs, the more the scale is tilted to Tersa.?? So? I'll re-iterate.......if you're a well healed garage warrior, or shop that occasionally process solid timber; segments will be cheaper because you likely won't reach the break even point the changeover labor of segments adds to the equation.?? Even cheaper than that will be reg. ol straight knives if you only change them once every 5-10 years.? Someone milling 1000's of board feet a week or month and changing blades frequently certainly should pay attention to how long a changeover is costing.? No money is being made while the machine is idle.
