Product category: Overburden casing ring bit

 

Recycle ring bit casing drilling system working principle:

1. Ring bit and casing shoe assembly is welded to casing prior to drilling. Lock the assembly into pilot bit with hammer. The pilot bit’s upper shoulder engages the shoulder of the casing shoe.

2. Hammer’s percussive energy is transferred through the pilot and ring bits, crushing rock . Part of impact energy advances casing.

3. On completion of drilling and casing , the drill string with pilot bit is retrieved by a slight reverse rotation to unlock the bayonet coupling . The ring bit stays in the hole , and can be recovered only if the casing is retrieved

4. Drilling continues to the desired depth in the bedrock using a conventional drilling.

 

Accelerate your drilling process with the incredible driving speed of the MRING Overburden Casing Drilling System Bits. The advanced technology incorporated within these bits allows for rapid drilling, significantly reducing the overall drilling time. Say goodbye to time-consuming drilling practices and embrace the efficiency and productivity that these bits offer.

FAQ:

1. What is hole hammer?

Pneumatic down-the-hole (DTH) hammer is a pneumatic drilling tool using compressed air as a power source. It is suitable for drilling in pebble, gravel, and hard rock strata. It is often used in building pile foundation construction, bridge, mining, geological exploration, hydrological wells, and other fields.

 

2. What is overburden fill?

Overburden Soil is an all-purpose, raw fill material that, depending on where it comes from, may contain a wide range of materials. In general, overburden soil lacks the organic matter and nutrients present in topsoil and can comprise sand, pebbles, clay, and stones.

 

3. How far can you directional bore?

What are the crossing's minimum and maximum lengths? The geotechnical constraints unique to a project dictate the maximum lengths and hole sizes; however, the 3,000 m effective outer range for heavy rig horizontal directional drilling.
