Sorry I couldn't resist. These bits are an old standby. They work great in soft materials like wood and plastic. Speedbor is very accurate. If you hit a nail they get dull fast but you can resharpen them. Even if you don't you're not out much. I know a lot of guys that use these for making custom bits. maybe they grind a taper on them for candle holders or they cut the shanks for stubby bits. The list goes on and on. I threw away my rack. I wrapped the bits in rubber bands so they would stay together. The whole bunch fits nicely in my Makita box. A must have item.
