NX Double tube Diamond Impregnated Core Bit
Roschen Impregnated diamond drill bits are designed to perform as grinders. Diamonds are embedded in an infiltrated or sintered matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock.
Impregnated Diamond Core Bits
The impregnated diamond core bit has emerged as the most commonly used type in the mineral exploration industry. The advantages of using impregnated diamond core bits over bits manufactured with other cutting media include
1: An extremely wide range of application.
2: A simple bit crown geometry that makes them less susceptible to in-hole damage than bits manufactured with other types of cutting media and as such are more tolerant of changing or banded geological formations.
3: Their multi-layered cutter arrangement results in better overall bit life than bits produced with other types of cutting media.
4: They are particularly well suited for drilling in hard, consolidated and non-abrasive formations.
Impregnation Depth
This refers to the thickness of the diamond impregnated matrix layer on a core bit crown as shown in the illustration to the right. Roschen offers many sizes of core bits with standard impregnation depths from 9mm to 20mm. Other customer defined impregnation depths are available on request.Unless otherwise specified, a standard 12mm impregnation depth is supplied for most of our customer.
Bit Crown Profiles
According to different formation and drilling condition, Roschen can 0ffer various of crown profiles against request.
