Amana 1/4″ spiral upcut bit

• Shank. 1/4” Shank.
• Cutting Diameter. 1/4″
• Cutting Height. 1-1/8”
• Spiral Flutes. Spiral-flute bits combine a shearing action in cutting with an auguring action in chip clearance. The shearing action yields an especially clean accurate cut while the auguring action clears chips from the cut.
• Up-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.
• Solid Carbide. Special unique carbide grade increased clearance geometry and razor-sharp cutting edges with polished flutes provide a superior finish and longer tool life especially in abrasive materials.
• Materials. Excellent for cutting hard wood, soft wood, MDF, plywood and laminate.
