Amana tool 46325 Solid Carbide Spiral 2 Flute Plunge 5/16 D x 1 CH x 5/16 SHK x 2-1/2 Inch Long Up-Cut Router Bit

Solid Carbide Spiral Plunge Router Bits Spiral 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.Unique carbide grade for longer lifetime in abrasive materialsProduces a superior finish and longer tool lifeRazor-sharp cutting edges/polished flutes'Can be used with hand-held, table-mounted portable routers and CNC machinesIndustrial qualityThese router bits are great for production settings and excellent for creating grooves and dado cuts in plywood and composite materials.
