Abstract
A cutting tool for bone, cartilage, and disk removal includes a body with a first radial array of helical flutes formed along the body with a continuous radius in a first helical direction. The body has a second radial array of helical flutes formed along the body with a continuous radius in a second helical direction opposed to the first helical direction and intersecting the first array of helical flutes. Each helical flute forms a pair of spaced apart rake surfaces, which collectively perform a first and second cutting operations along a side of the body such that the intersecting rakes balance the cutting operation thereby minimizing axial loading of the cutting tool to permit bidirectional cutting while minimizing g inadvertent axial translation of the tool.
