Reaming shell High wear resistance HQ Diamond Core Bit FOR in cutting non-ferrous materials
Available Size: HQ
application: in cutting non-ferrous materials
Brand Name: yaheng
feature: High wear resistance
Description:
1. 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.
2. 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.
3. 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.
Features :
1. Wide hardness range.Yaheng could produce the bit hardness from 1
to 12
2. High drill speed.
3. Longer service life.
4. Competitive prices.
5. 15 years experience in manufacturing diamond core bits.
