Reamers feature increased stability and reduced vibrations due to
the specially designed spiral pads,which provide increased contact
with the circumference of the hole.
Our reaming shells experience longer life in the field due to the
greater number of diamonds and high-grade carbide reinforcements.
Reaming shells are designed to ensure drilling fluid flow, maintain
size of drilling hole and stabilize drill rod through the sprial
pad.
Features:
1.High penetration rate and drilling effeciency.
2.Long service life;
3.Good gauge effect;
4.High cost performance;
5.Wide usable range, diamond core bits are the most commonly useful
bits in the mineral exploration industry.
