cutterhead
Rotating blade assembly
A cutterhead is the rotating component of a machine that does the actual cutting.
In woodworking planers and jointers, it's the cylindrical drum fitted with blades that shaves wood smooth.
Dredging machines use massive cutterheads to break up soil and sediment underwater.
The planer's cutterhead needs new knives.
