It looks like the final grind of the drill was wrong. Somehow it passed the test and was sent for sale, which Freud says is not of their normal quality. The tip looked normal on a quick visual inspection, but was not a perfect V-shape. Instead, cut out a V shape with a U shape at the bottom of the groove. The enlarger showed that the tip of the carbide cutter was actually two small dots next to each other with no material in between to set the necessary point between the two cutting edges to cut the correct "VEE" flute shape I needed. of.Time is not on my side, I bought another cutter from a local supplier and got the job done just in time.
