Abstract:
The present invention relates to a drill having an aggressive drill point geometry. The point geometry allows greater stability and feed rates, while decreasing the heat generated at drill point. The present invention is provided by a drill comprising drill body having at least two helical flutes, a pair of cutting surfaces on an end of the drill body, a web formed between the two cutting edges, and a web thinning notch formed on either side of the web. Each notch forms a notch cutting edge having a positive rake angle.
