Reverse Circulation Hammers & Bits
Roschen offers a complete line of Reverse Circulation hammers and spare parts, which can replace Roschen series Reverse Circulation Hammers & Bits. Hammers are available in a wide range of sizes and styles, to provide maximum performance and longevity on all RC drilling jobs.
Reverse Circulation hammers are designed with an inner sample tube that extends through the center and into the top of the hammer bit. The RC 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 a RC hammer is used, to help direct the return air and cuttings up through the face of the bit.
Conventional DTH hammers can also be used 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.
REVERSE CIRCULATION DRILLING HAMMERS AND BITS
We offer a full range of reverse circulation down the hole hammers and bits, to suit all depths and ground conditions.
Due to its high-quality sample results, and speed of operation for shallower holes, reverse circulation drilling is becoming increasingly popular around the globe. In fact, it's the most widely accepted chip sampling method. This is largely due to our innovative designs, and we're continuing to develop the capabilities of this valuable sampling method. Partner with Roschen for your reverse circulation down hole hammer drilling.
Advantages:
1. High penetration rates in all rock conditions
2. Quality samples from areas of lost circulation
3. Large, uncontaminated sample return
4. Increased longevity means lower cost per meter
5. The option of diamond-enhanced carbide bits for deep and abrasive drilling conditions, with no bits sharpening required
