Diamond reaming shell is used together with diamond drill bits, maintaining the hole size and improving drilling stability

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. At present, ZMmakes five types of reaming shells, it includes:

• ---Surface set Diamond Type
• ---Impregnated Diamond Type
• ---Tungsten Carbide Type
• ---PCD Type
• ---Electroplated Diamond Type

   At present, ZM also supply the Reaming Shells with the length 10 inch (254mm) and 18-3/8 Inch (467mm). They are available for most wireline core barrel assemblies (WLA to WLP). Their purpose is to assist in minimizing the degree of drill hole angular deviation in target or deep hole drilling situations.  

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 strucures (Single tube bit, Double tube bit and wire line coring bit, etc.) and of various bit standards (domestic and foregn standards.)
