Product Description

Factory MK3E Eccentric Overburden Casing Drilling System Bit for Gold Exploration

Product Description

KINGDRILLING provides rock drilling tools including civil engineering projects, tunneling, surface drilling, anchoring, foundation projects, and piling. This is true for all drilling methods such as top hammer, DTH and rotary drilling.

Function of Overburden Casing Drilling Bits:
Overburden casing drilling bits are specifically designed to address the challenges associated with drilling through overburden formations. The primary function of these bits is to facilitate the simultaneous drilling and casing installation process, allowing for efficient and cost-effective well construction. Here is an overview of how overburden casing drilling bits function:

1. Drilling Process
During the drilling operation, the overburden casing drilling bit rotates at the bottom of the drill string, cutting through the overburden formations. The cutting structure of the bit disintegrates the rock and soil, creating a borehole for the casing to be installed.

2. Casing Installation
As the drilling progresses, the casing shoe attached to the overburden casing drilling bit guides the casing into the borehole. The reamer wings on the bit help enlarge the hole diameter to accommodate the casing, allowing for smooth and efficient casing advancement.

3. Casing Advancement
The retractable reamer wings on the overburden casing drilling bit retract as the casing advances, reducing resistance and preventing casing jamming. This continuous casing advancement mechanism ensures that the casing is securely installed in the borehole without delays or complications.

4. Borehole Integrity
Throughout the drilling and casing installation process, overburden casing drilling bits help maintain the integrity of the borehole by minimizing hole deviation, stabilizing the casing, and preventing collapse or caving in of the formation.
