Product Description

MK-MRS660 Symmetrix Overburden Casing Drilling System for Water Well Casingl

Product Description

MRE Concentric under reaming drilling system is designed for unstable ground conditions. In the process of drilling, it could carry down the casing pipe to the hole to protect wall to achieve drilling work. At clockwise condition, eccentric part expanded to bring the casing tube into hole. After finished, eccentric bit closed anticlockwise and then can be lift up by the drilling machine. This type is especially suitable for diameter 114-273mm.

Long service life of drilling rig: Alloy material, with long service life, superior to similar products.
High drilling efficiency: The drill buckle is wear-resistant, and the drill bit remains sharp, greatly improving drilling speed. Stable drilling speed, scraping the drill bit and damaging the rock.
Good performance: The new diamond drill bit has strong wear resistance, good diameter protection, and can effectively use cutting teeth.
