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.

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

The half round engraving tools are offered with a wide range of tip sizes and angles to accommodate many engraving styles.
