Rotary drill bits

Jump to navigation Jump to search

Rotary drilling uses two types of drill bits:

Roller-cone bits are generally used to drill a wide variety of formations, from very soft to very hard. Milled-tooth (or steel-tooth) bits are typically used for drilling relatively soft formations. Tungsten carbide inserts bits (TCI or button bits) are used in a wider range of formations, including the hardest and most abrasive drilling applications (see Fig. 1). Fixed-cutter bits can drill an extensive array of formations at various depths, and include:
