Spiral Fluted HSS Step Drill Bit Set, Sizes 0/9, 1, 2 in Plastic Case

The ground and spiral CBN slots ensure quiet operation and high cutting performance. The chip flow is optimized, so even long and unbreakable chips are easily removed. The optimized chip flow protects the cutting edges and reduces the build-up of edges and cold welding marks. The cone facilitates the removal of the tool from the material.
