Amana Tool 1/4 in Shank 2 Flute Carbide High Production Straight Plunge Router Bit, 1/2 in x 2-1/8 in
AMN45226 MFG #: 45226
Use a two-flute bit where fine finish is paramount.
Two flutes balance the bit, eliminating vibration that degrades the cut finish.
Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced.
