|---|---|---|---|
| Processing Type: | Forging | Use: | Core Drilling |
| Brand Name: | Sinocoredrill | Country Of Originn: | China |
| Highlight: | geological reaming shell,nq reaming shell,reaming shell for hard rock drilling |
||
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.
