I got this drill bit for drilling holes with a plunge mill. I work with radiant pine that turns to fine dust. Cuts very well and punches a 2 inch deep hole in one to two passes. I was concerned that the drill would not remove the sawdust as the blade is much thicker than the drill. It leaves dust in deep holes, but it's packed loosely and blows out easily. A bit of vibration, but I expected it to last a long time in a handheld router spinning at 30,000rpm.
