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.

These Compression spiral bits are designed for CNC applications requiring high feed rates and a clean finish. Particularly suitable for double-sided melamine or laminated material. Special unique carbide for longer lifetime in abrasive material.

Slow Spiral (Low Helix) Router Bits are designed to lessen the up or down force to help keep chip outs from happening on the top of the material. Great for more brittle substrates.
