Product Description

MRING Overburden Casing Reaming Drilling System with Ring Bit for Engineering Construction

Product Description

Rock drilling tools factory KINGDRILLING professionally produce Ring wing bit concentric drilling systems by down the hole hammer which are designed to drill and case a hole simultaneously through unstable ground conditions. A driver bit and a ring are assembled to a complete RING system bit which is suitable for 114-1067mm diameter casing tube.

Overburden casing drilling (OCD) is a drilling technique that involves drilling with a casing in place. The system typically consists of several key components:

1. Casing: A steel casing, often with a carbide shoe at the bottom, is used to advance through unstable overburden formations while providing stability to the borehole.

2. Drill Bit: Various types of drilling bits, such as tricone or PDC (polycrystalline diamond compact), are used depending on the specific geological conditions.

3. Reaming Shells: These are used to enlarge the hole diameter to accommodate larger casing sizes or to stabilize the borehole in loose formations.

4. Casing Advancement Equipment: This includes tools like casing hammers or rotation devices to advance the casing while drilling.
