The present invention relates to a V-notched web formed on a drill insert of
a drill tool assembly. The V-notched web allows greater stability and feed rates,
while decreasing the heat generated at the insert tip. The present invention is
provided by a drill insert comprising a drill insert body having at least two cutting
edges, a web between the two cutting edges, and a web thinning notch formed on
either side of the web. Each web thinning notch forms a notch cutting edge having
a positive rake angle.
