Product Name: 133mm MK5E Overburden Eccentric Casing drilling bit with DHD340 shank

Product category: Overburden eccentric casing bit

Matched casing pipe OD: 133mm

Matched hammer: Hammer DHD340

MK5E eccentric casing bit feature:

When drilling in soft and loose ground with scattered boulders, the soil and clay are caved in, which creates drilling difficulty to withdraw the DTH drilling equipment and lowers the drilling speed.

To overcome this problem, KINGDRILLING Eccentric Type Overburden Casing Drilling System to enable drilling and lowering the casing simultaneously. This prevents the soil from collapsing into the drilled hole.The systems are designed to drill the hole diameters bigger than the casing diameter. When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole. If the bed-rock level is reached and further drilling is needed, you can simply change the bit to a conventional DTH bit.

3. Superior performance:Stable and reliable performance, high drilling speed

FAQ:

1. What is the purpose of surface casing?

Surface casing is set to provide blowout protection, isolate water sands, and prevent lost circulation. It also often provides adequate shoe strength to drill into high-pressure transition zones.

2. How much PSI do I need for air tools?
Between 70 and 90 PSI

Most air tools require between 70 and 90 PSI. Any light-to-medium-duty air compressor can easily handle 90 PSI, but you always want the compressor to supply more flow than needed. Pro Tip: Always respect a PSI rating. If you don't supply enough air volume, the tool won't operate correctly.

3. Where does overburden go during a mining operation?
Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant.
