Drilling pen blanks

George Fitzpatrick - Springfield MA
>The last couple times I have turned pens, I ran into a problem. I cut the blanks to the appropriate size, put them in a self-centering drilling jig and start to drill. I clear the bit of debris three or four times, but right at the end of the blank, hear a pop, pull it out, and the blank has split. Has happened on cocobolo, bocote and teak. Have done probably 25 pens with this drill bit, and still seems to be sharp. Am I doing something wrong here or just bad luck?
