It also acts as a stabilizer for drill bit,sizes like nq,hq

 

 

Reamer is set with natural or synthetic diamond, and it is used to couple the dril bit with the core barrel. Its main function is to ream the hole to the correct constant specific diameter which ensures adequate clearance for the core barrel and sufficient clearance for the new bit which replaces an old one. It also acts as a stabilizer for drill bit.

 

 Description of reaming shells

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, ZM makes five types of reaming shells, it includes:

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