The quick-change taper drill countersinks work well. Runing at higher speeds helps the tapered drill in shedding chips, otherwise I've had problems with the chips packing solidly into the flutes. Be award that replacement tapered drills from Rockler only work with the Insty-Bit Quick-Change Taper Drill Countersink model they sell. Replacements don't have the 1/4" quick-change shank.

The Insty drive set is one of the best things in my shop. I use the drive in so many places, and so many projects. I've had my set for 2 years, and just broke my first tapered bit. It so easy to use, slides off to drill, counter sink and slides back on to screw in the screw. Every woodworker would love this tool!

I use these bits all the time during the construction of my Glen L mahogany boat. I am driving silicon bronze screws in hard wood and the screws won't work without the taper bits.
