I use the standard Miebach (Colt) brad points, and the pen bits. They are both the best brad points I have encountered. The Pen bits clear incredibly well, and I can drill 2.5" through hardwood end grain without chipping, blowout or having to drill and extract numerous times to clear the flutes. Expensive, but great product. And, they are available in sets from The Best Things. http://www.thebestthings.com/newtools/miebach_bits.htm
There are some videos out there on these bits as well, but I do not remember where.
