Upgrade to a SHELIX® Helical Spiral Cutter Head today and forget about replacing knives for a really long time. 

All insert knives in a SHELIX® Cutter  Head are sharpened on all four edges. When one edge becomes dull, simply rotate the knife insert and continue working. 

There is no need for adjusting any knives as you needed to do with your old head. These inserts auto-locate right into position every time.  Best of all, the inserts are made from solid carbide, which means that each single edge per insert will last you a lot longer than your old steel knives.

The name SHELIX®  comes from "SHEar" and "heLIX" - SHELIX®The SHELIX® HELICAL SPIRAL Cutter Head combines the advantages of shear, helix and spiral tooth action- resulting in a smoother & cleaner cut across the board.

With the staggered tooth design, there is no longer a need to replace brand new straight blades, if you happen to run a nail or hard knot through you planer. With the SHELIX® design, you just need to rotate or replace 1 or 2 inexpensive inserts.
