Diamond Reaming Shell

DiamondReaming Shell


The recommended practiceis to alternate two reaming shells in each hole drilled to maintain hole diameter.  Whenchanging bits, the diamond reaming shell should be checked for wear using thebit and shell wear gauge.  Failure toobserve these recommended practices could result in a poorly stabilized bit oran undersized hole requiring costly reaming. Our diamond reaming shell includes impregnated diamonds and surface setnatural diamonds reaming shell.

China Drilling reamers feature increased stability and reduced vibrationdue to specially designed spiral pads. The design provides increased contact with the circumference of thehole.  China Drilling reaming shellexperience longer life in the field due to the greater number of diamonds andcarbide reinforcements.

China Drilling provides different types of reamer configurations toensure the right reamer for the right application.  The magnum and premium reamers containtungsten carbide to absorb impact and improve life through decreasing erosionof the pad.

Impregnated diamond reaming shell is designed with synthetic diamonds onthe surface of the reamer pads.

Natural diamond surface set reamer: Large size natural diamonds are placed in the pads.

Magnum reamers
Alternating rows of tungsten carbide and TSDpins.  Can be used togather core samples that cannot be contaminated by natural diamond fragments.

Premium reamers
Contains the most natural diamond content of all the reamers.  Each pad is protected with Tungsten carbidestrips on the leading and trailing edges to help protect gauge and improveservice life.

Diamond adaptor coupling
Used to stabilize the core barrel.  Itcontains a core barrel thread on one side and a core barrel thread on theother.  Can be used tokeep the hole to the required size.
