Amana Tool 46361 CNC Solid Carbide Spiral Plunge for Solid Wood 1/2 D x 1-1/4 CH x 1/2 SHK x 3 Inch Long Down-Cut Router Bit

Solid Carbide Spiral Flute Plunge Router Bits for Solid Wood
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 “down-cut” cuts from the surface down, leaving a smooth edge at the surface of the wood.
