Amana Tool 47182 Helix Bit 3/4 Diameter 1/4 Shank Router Bit

The Dynabit line features a modest down-shear for an excellent finish. The helix bits have a spiral-like twist to the cutting edges making them especially good on difficult materials such as melamine. An adhesive-trapping gap between cutting edges & pilot bearing is featured on tools #47111 & #47113.
