Reaming shell is set with natural or synthetic diamond,used to couple the bit with core barrel and function is to ream the hole

What is reaming shell?

Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability. According to the cutting media on the reaming shells.

ZM makes five types of reaming shells,

Surface set Diamond Type

Impregnated Diamond Type

Tungsten Carbide Type

Their purpose is to assist in minimizing the degree of drill hole angular deviation in target or deep hole drilling situations.  

Diamond reaming shell is used together with diamond drill bits

Diamond core bits are widely used in the fields of geological exploration, engineering-oriented, hydroelectric and building engineering. Diamond drill bit series include the bits of different structures (Single tube bit, Double tube bit and wire line coring bit, etc.) and of various bit standards (domestic and foreign standards.).
