Amana 46318 Features:
•  Spiral-flute bits combine a shearing action in cutting with an augering action in chip clearance.
•  The shearing action yields an especially clean, accurate cut, while the augering action clears chips from the cut.
•  The “up-cut” shears from the bottom up, pulling chips from the bottom up, thus allowing deeper penetration with less stress on the tool.
•  An excellent choice for mortising.
