MK3E Overburden Eccentric Casing Drilling System Bit for Underground Coal Mine

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.

Features of Overburden Casing Drilling Bits:

1. Dual-Function Design
Overburden casing drilling bits are designed with a unique dual-function capability that allows drilling and casing installations to be performed simultaneously. These bits are equipped with a casing shoe that guides the casing through the overburden layers while drilling, eliminating the need for separate drilling and casing operations.

2. Reamer Wings
Most overburden casing drilling bits feature reamer wings that help stabilize the drilling process and maintain the borehole's integrity. These wings are typically retractable, allowing for easy casing advancement through challenging formations.

3. Cutting Structure
The cutting structure of overburden casing drilling bits is engineered to handle a wide range of formation types, including soft soils, hard rock, gravel, and boulders. The robust design of the cutting elements ensures efficient drilling performance and extended bit life.

4. Casing Advancement Mechanism
One of the key features of overburden casing drilling bits is their casing advancement mechanism, which enables seamless casing installation while drilling. This mechanism is designed to prevent casing sticking and ensure smooth casing advancement in various ground conditions.

5. Compatibility
Overburden casing drilling bits are available in a variety of sizes and configurations to accommodate different casing diameters and drilling requirements. They are compatible with various drilling rigs, including rotary, percussion, and reverse circulation systems.
