This cutterhead is the original size. You will need to remove inserts from the cutterhead before installing on the machine. The two bearings 6204+6202 are already installed on the cutterhead.
Reduced noise and tear-out, produce much smoother finish on difficult woods.
The patented indexable 4 cutting-edge double-layer insert and screw make it much easier to mount the knives on the cutterhead.
The indexable inserts allows you to rotate it if one knife edge is dull or nicked.
Including tool kit: 5 spare inserts/ 10 spare screws/ two T wrenches
