DTH Bit Head Designs

Hammer bits are available with multiple head designs suitable for a variety of rock formations.

Concave, flat, and convex are the most common head designs. Additional designs are available on request. Please contact your Hole Products representative for additional information.

BIT HEAD DESIGNS DESCRIPTION
CONCAVE Concave DTH hammer bit head. The concave bit design is an excellent all around bit, suitable for soft and hard formations. The cone shaped face design provides good stability during drilling, allowing for straighter holes while reducing equipment vibration. The carbide configuration design gives added penetration in many formations.
FLAT Flat DTH hammer bit head. Used for general purpose drilling, the flat face design is considered effective in very broken ground as well as hard formations that tend to over drill.
CONVEX Convex are suitable for most drilling applications, particularly hard, abrasive rock to give a combination
of speed and good service life.
