I put an insert cutter head in my old P100 planer, that carbide lasts soooooo much longer than steel! My excuse was that my wife wanted to re-plane a bunch of ipe decking, and I didn't want to change the HSS blades for her every fifth board (or however many, I bet they would dull fast though). I've had that cutter head since 2015 and only just recently rotated the carbide inserts the first time. Love that setup!This planer uses the square blades that are mounted to a helical drum. So dull blades can be rotated 90 degrees to give the cutter new blades to cut with. I also purchased some spare blades in case I hit a nail or something.
