Method of forming a drill bit with debris conveying flute

A method of forming a drill bit with a chucking end, a cutting end and at least one flute between the ends, the at least one flute including a web means and a debris channel, the web means including a first surface and a second surface, comprising the steps of:

• providing a pair of rotating dies;
• providing a blank;
• moving said blank into said dies;
• impressing said flute into said blank by deforming walls of the blank along the length of the blank by cold rolling said blank between said pair of rotating dies and during passing of said blank through said rotating dies, forming said first surface substantially parallel to a shank longitudinal axis and continuous with a debris channel surface, and forming said second surface at an angle from about 100.degree. to about 120.degree. with respect to the shank longitudinal axis, wherein said second surface extends inwardly, forming the base of said debris channel, and during said cold rolling forming said debris channel surface between said first surface and said second surface, and forming a side wall of said debris channel such that the side wall is at an angle of from about 10.degree. to 20.degree. with respect to said shank longitudinal axis and creating a ratio of axial length of said first surface to axial length of said debris channel surface at about 2:1 to 4:1.
