8-Pc CNC Solid Carbide Up-Cut Spiral Router Bit Collection

Solid Carbide Spiral 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.
