The Center Drill Bit have two flutes and are designed for machining in one downward direction only. These long-life tools are available in various cutting diameters, lengths and shank diameters.
For precision holes, using a Center Drill Bit compared to helixing with an end mill is a better solution. A drilled hole will give you a consistent diameter all the way through the material, while an end mill deflects slightly and creates a tapered hole. Also, for a high volume of holes, using a Center Drill Bit is much faster. If you need to a deep hole, sometimes a drill is your only option due to the longer cutting lengths.
