product introduction
::LEANOMS
A Reverse Circulation Drilling Hammer is a specialized drilling tool used in reverse circulation drilling operations. In reverse circulation drilling, the drilling fluid and cuttings are brought to the surface through an inner tube, allowing for efficient and high-quality sample collection from the subsurface.

Best RC Drill Bits and DTH (Down-The-Hole) drill bits are both types of drilling tools used in mining, construction, and oil exploration industries, but they serve different purposes and have distinct characteristics. Here's a comparison between the two:
Best RC Drill Bits (Reverse Circulation Drill Bits):
Drilling Method: RC drilling is a drilling method where the drilling fluid flows down the annular space between the drill pipe and the borehole wall. Cuttings are brought up to the surface through the center of the drill pipe in a reverse manner.
Bit Design: Best RC Drill Bits are designed to efficiently collect and transport cuttings from the bottom of the hole to the surface. These bits have a wide opening at the center, allowing cuttings to be carried up through the inner tube of the RC drill pipe.
Application: RC drilling is commonly used for mineral exploration and grade control drilling. It is effective in softer formations and is often preferred for sampling purposes because it provides high-quality samples due to minimal contamination.
DTH Drill Bits (Down-The-Hole Drill Bits):
Drilling Method: DTH drilling is a percussion drilling technique where the hammer is located behind the drill bit. Compressed air is used to drive the hammer's piston, which strikes the back of the bit, creating a powerful hammering effect that breaks the rock.
Bit Design: DTH drill bits are designed with various types of carbide buttons or chisels on the face, depending on the rock formation. These bits are engineered to withstand high-impact forces and break hard rock formations effectively.
Application: DTH drilling is commonly used in mining, quarrying, water well drilling, geothermal drilling, and construction projects. It is suitable for hard and abrasive rock formations where other drilling methods might be less effective.
Key Differences:
Drilling Method: RC drilling uses a reverse circulation method for drilling and sample collection, while DTH drilling uses a percussion method with a hammer located behind the drill bit.
Cuttings Removal: Best RC Drill Bits efficiently transport cuttings to the surface through the center of the drill pipe, ensuring minimal contamination of samples. In contrast, DTH drill bits rely on air pressure to remove cuttings and break rock.
Suitable Formations: RC drilling is ideal for softer formations and is often used for exploration purposes. DTH drilling is suitable for hard and abrasive rock formations where high-impact drilling is required.

Transportation
LEANOMS
Wooden Crates: RC hammers are often packed in sturdy wooden crates. The hammer is securely placed inside the crate, and additional padding and cushioning materials, such as foam or rubber, are used to prevent movement and provide protection against impact during transportation.
Cardboard Boxes: Smaller RC hammers or components may be packed in heavy-duty cardboard boxes. These boxes are designed to withstand the weight of the hammer and provide adequate protection. The hammer and any accompanying components are usually wrapped in protective materials before being placed inside the box.
Bubble Wrap and Plastic Sheeting: The RC hammer, along with its components, is wrapped in bubble wrap or plastic sheeting to protect it from dust, moisture, and minor impacts. This additional layer of protection ensures that the hammer reaches its destination in optimal condition.
