Hermance Helical Cutterhead
Available from Hermance Machine Co.
Hermance's Helical Cutterhead, available for planers, jointers, and moulders is designed to offer several important advantages over traditional spiral cutterheads.
1.Hermance helical cutterhead knives are turned at an angle and tilted. Many spiral heads have the knives strike the wood at a 90 degree angle. Only the Hermance heads cut with a true shearing action giving an incredibly smooth finish without needing special knives.
2.Hermance cutterheads are engineered to support carbide knives on three sides to reduce blade chipping and cracking.
3.Hermance cutterheads are aerodynamically designed to run more quitely than straight blade or any other cutterheads. Preliminary tests have shown a 15-20dB reduction when run on an SCM Superset compared to a straight blade moulder head.
