Amana 46315-K Spektra Solid Carbide Upcut Spiral Bit, 1/4" Diameter, 1/4" Shank

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.DirectionUp-Cut(D) Diameter1/4(B) Cutting Height1(d) Shank1/4Overall Length (L)2-1/2Flutes2
