Face Design

Hammer bits are offered in three basic face designs: concave, convex, and flat face. Each are designed for specific applications and conditions and for varying rock types and hardness.

Concave is an excellent all around face design and is used as a general-purpose bit for most conditions while drilling a very straight hole.

Convex bits are used for a combination of speed and service life. Having 2 gage rows, they are also suited for hard, abrasive rock.

Flat face bits are best suited for broken or fragmented ground and hard formations.
