The Christen 05-8 drill grinding machine produces the four-facet point grinding method on left and right twist and flat drills within the capacity of .019" to .314" dia. (0, 5-8mm).
The well known advantages of the four-facet point are:
-self centering properties
-close tolerances of the drilled holes
-improved tool life owing to reduced drilling stresses
-simple adaption of the cutting angles to the material to be machined
-good reproducibility of given cutting angles
