Reaming shell is set with natural or synthetic diamond, and it is used to couple the drill 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.

Diamond Reaming Shells are very important reamer tools to be used together with bits in core drilling. Its

main functions are maintaining the borehole gage, improving drill rods stability and protecting lower part

of drill rod from excessive wear.

Helical type reaming shells provides good passages for water flowing, the matrix is wear proof and its

service life is long.

DESCRIPTION:

Reaming shells (with double pads or three pads) are suitable to use in all formation conditions ranging

from broken and abrasive to consolidated and non-abrasive. As this kind of reaming shell is physically

longer than the standard type, it is necessary to use an appropriate inner tube extension in order to

compensate for the difference in overall reaming shell length.

Specialisted in producing varies kinds of diamond core bits in different international standard size for soft,

medieum to hard rock formations.

Features:

• Acts as a stabilizer for drill bit.
• Be set with natural or synthetic diamond.
• Our reaming shells enjoy the best quality and most special design in the industry.
• High penetration rate
• High core recovery ratio
• Long life of drilling service
