Modern Design Professional Alloy Tipped Knifes Helical Spiral
When you think of the straight knives in your original cutter head,
they work just like a fan that moves air at very high speeds. This
is what is causing the high noise levels when no wood is passing
through the machine. With a helical cutterhead, the knives are only
15mm (about ½” wide) and the air movement caused by each individual
knife causes so much less noise that even the addition of all
knives doesn’t generate as much noise as one straight knife.
Chip-outs are the number one problem for many woodworkers when it
comes to planing wood. Especially some hardwoods such as Maple
always tend to show small holes in the surface after the wood went
through the planer or over the jointer. This is caused by the
straight knives when they start to become dull as the wood
sometimes offers such density that the knives no longer cut but
break or actually tear wood chips out of the surface. Many spiral
cutter heads on the market reduce this problem as only small single
knives cut the wood at any given time but this is where the cutter
head makes all the difference: The knives are sitting on a diagonal
angle on the head and therefore, offer a SHEAR cut instead of a
straight cut. This SHEAR cut virtually eliminates chip outs.
