The present invention relates to a drill (10) 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 (16) having at least two helical flutes (18), a pair of cutting surfaces on an end of the drill body (16), a web (36) formed between the two cutting edges (30), and a web thinning notch formed on either side of the web (36). Each notch forms a notch (40) cutting edge (44) having a positive rake angle.
L'invention porte sur un foret (10) doté d'une géométrie de point de foret dynamique. Cette géométrie de point offre une plus grande stabilité et des vitesses d'alimentation plus élevées, tout en diminuant la chaleur générée au niveau du point de foret. L'invention concerne un foret comprenant un corps de foret (16) doté d'au moins deux cannelures hélicoïdales (18), d'une paire de surfaces de coupe sur une extrémité du corps de foret (16), d'une bande (36) disposée entre les deux rebords de coupe (30), et d'une encoche d'amincissement de bande placée sur l'un des côtés de la bande (36). Chaque encoche forme un rebord tranchant (44) d'encoche (40) doté d'un angle de pente positif.
