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.

Flush trim bits cut the wood on your project so that it is flush with the template edge. The downshear cutting edge moves the chips away from the router.

Unlike a standard Flush Trim bit, these bits allow a small overhang.
