High Drill Speed HQ Diamond Core Bit , PDC Drill Bits For Concrete / Rock

Reaming shell HQ   High drill speed   Diamond Core Bit   for Hard Rock Formation

Quick Details:

Available Size: HQ

application: Concrete

Brand Name: yaheng

feature: High drill speed 

Description:

   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 comstant 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.  The matrix ring of PCD Reaming Shell is set with Polycrystalline Diamond. The Polycrystalline Diamond is produced from synthetic diamond sintered with bond under high temperature and high pressure; it has an impressive abrassion resistance and high thermal stability. The PCD reaming shell is suit for soft to hard rock formations. Surface set reaming shells are set natural diamonds outside of the shells, generally, with the stone size 20/30. The rock cutters are flushed smoothly as the well design of the waterways. 
Usually, we can make two types of Surface Set Reaming Shell, one is Spiral Rib Type, another is Spiral Segments Type. 

 
Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability.
 

application:

  impregnated diamond core bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series.

 Surface set Diamond Core Bits are mostly suited to soft formations or using low powered drills, as they operate more effectively than impregnated bits at low surface speeds. Available with different stone sizes, face profiles and waterway arrangements to suit different conditions. All supplied with highest quality natural drilling diamonds.

Impregnated Diamond Core Bits can drill a broad range of formations from the softest to the hardest rocks. Manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. All bits have T.C. and Diamond gauge protection. Available in 6 standard matrix types to suit rock formation.
 

Matrix rated 7,  core bits are manufactured using only the highest grade diamonds, which are coated with titanium in order to preserve their cutting abilities throughout the bit furnacing process. Furthermore, they are manufactured using a new unitary furnacing process regularizing the consistency of the tools.
