RC Tools For Drill
RC DTH Hammers are available in a wide range of sizes and styles, to provide maximum performance and longevity on all RC Tools For Drill.
RC DTH Hammer is designed with an inner sample tube that extends through the center and into the top of the hammer bit. The RC DTH Hammer exhausts the air between the bit splines and over the face of the bit. This forces the sample into the recovery holes in the face of the bit, through the center of the hammer and upward through the drill rod inner tubes to the surface for collection, The use of a shroud or collar is required when an RC DTH Hammer is used, to help direct the return air and cuttings up through the face of the bit. Conventional DTH hammers can also be in RC drilling operations, but increase the potential for sample loss and contamination. A conventional DTH hammer is used in conjunction with a cross-over sub located between the hammer and drill rod, The sample travels from the face of the bit up the outside of the hammer and into the cross-over sub. The sub directs the sample up the center of the dual wall rods and to the surface.

RC Bit Head Designs
RC Tools For Drill 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.
CONCAVE
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 to many formations.
FLAT
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 is suitable for most drilling applications, particularly hard, abrasive rock to give a combination of speed and good service life.
