re: Helical Heads

I just rotated the carbide inserts on a 24" North Tech planer and the cut came out perfect.I was holding my breath.This one has 144 helical carbide inserts, but I didn’t need to rotate all of them.
I would like to find a hardened steel torx wrench.Some of the torx screws were
really tough to get out and I went through
a fair number of steel bits.Mild steel bits
of that size are really weak.Don’t want to crank them down.I think about 12lbs. of torque should work.I guessed.
Very happy with the cut, reduced noise level and ease of maintenance.
