2900 Series. Two Flute Roughing Compression Spiral
This style of compression bit manufactured exclusively for hard-to-cut materials. This tool is used in hogging operations where the compression geometry of the bit helps break up the cut and neutralises the force of the bit with both upshear and downshear rotation. Can be used in solid woods, wood composites and any difficult-to-cut materials. This tool will leave a "rippled" edge cut. L = left hand rotation. (m) = 1/4" upcut for mortise cuts or thin materials.
