Diamond reaming shells are important tools to be used together with bits. The main functions are maintaining bore hole gage, improving drill string stability and protecting lower drill string from excessive wear.
Bore Hole Gage
Maintains precise hole diameter during drilling operations.
String Stability
Significantly improves drill string stability in various formations.
Wear Protection
Protects the lower drill string from excessive abrasive wear.
Design Advantage: Helical type reaming shell provides a good passage for drilling fluids. The matrix is wear-proof and the service life is exceptionally long, ensuring high efficiency in core drilling projects.
What are the primary functions of a Diamond Reaming Shell?
Diamond reaming shells are designed to maintain the bore hole gage, improve the stability of the drill string, and protect the lower part of the drill string from excessive wear during the drilling process.
Why is the helical type design preferred for reaming shells?
The helical type design provides a superior passage for drilling fluids, which helps in efficient cooling and removal of cuttings, leading to a longer tool service life.
Which standard sizes are available for Wireline Reaming Shells?
We offer a wide range of sizes including BQ, NQ, HQ, PQ, as well as T2-series (T2-46 to T2-101) and S-series metric sizes.
How does a reaming shell protect the drill string?
By ensuring the hole stays at the correct diameter, it prevents the drill string from rubbing directly against the rock wall, thereby reducing abrasive wear.
Are these reaming shells compatible with single-tube systems?
Yes, we provide specific categories for Single-tube, Double-tube, and Wireline systems to meet various drilling requirements.
What makes the matrix of these tools durable?
The matrix is engineered to be highly wear-proof, utilizing high-quality diamond materials to ensure a long operational lifespan even in tough geological formations.
