Applications:

1.Cross cutter core barrel is mainly used to break rock cores which remain in the borehole after using a core barrel. 

2.It is also suitable for drilling hard, jointed rock (less than 100Mpa) and for penetrating through layers containing boulders.

Features:

1.Cutting ring with rock drilling bits helps release the internal stress of rock

2.When drill in the full fracture rock layer, crossing cutter makes it easy to carry soil

3.Kelly box: 130mm,150mm,200mm(optional)

4.Barrel adopts spiral wear-resistant strips for anti-attrition to prolong the service life

5.Many alloy teeth are used for higher drilling efficiency

6.Heightened design with high construction efficiency, reducing construction cost
