Drilling some holes over 2" deep in 6061 T6. They are 5" down in a bore so I'm using an ER11 collet extension just to be able to reach the starting point. What design drill would be best for chip removal? The drill needs to have enough flute length and 4" oal would be good.I have no coolant on my CNC but will use a peck cycle. Suggestions on peck increments, feed rate welcome also.
