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 inadvertent axial translation of the tool. |
