The Mincon Ring-Bit Systems use our patented Spiral Flush air-control technology to avoid damage or disruption in complex ground conditions or existing foundations, thus leading to safer drilling.
​
In large-diameter drilling applications energy transfer to the ground is significant, but Mincon’s DTH hammers have a high-frequency design that lets them operate above the nominal frequency of the ground. This technology mitigates excess ground vibration by cycling hammers above the natural harmonic frequency of the ground.
​
All Mincon Geotechnical products are manufactured to exacting tolerances using the very best materials and tungsten carbide buttons, ensuring excellent service life for serious contractors.
​
Our Geotechnical Drilling solutions are backed up by a global service footprint and highly experienced consultants with in-depth knowledge of Mincon products and cutting-edge geotechnical techniques.​​
Construction and Geotechnical Solutions
Mincon’s Geotechnical Drilling Ring-Bit Casing Advancing Systems offer solutions for a variety of construction techniques, including foundation drilling, pipe pile-walls, forepoling, well drilling, and anchoring.
SPIRAL FLUSH DESIGN
-
Flushing channels are crosswise to the drilling direction
-
Back flush creates a vacuum to the pilot bit face area
-
Air channels are above the ring bit cutting edge
CONVENTIONAL DTH DRILLING
Conventional DTH drilling has two problem areas:
​
-
Pressurised air over drills material. Over drilling removes more material than anticipated changing the ground’s original characteristics impacting nearby structures.
-
Air that is blown forward travels long distances in loose ground or soft clay. This can cause severe damage to nearby buildings and structures.
​​
As a result, the use of conventional DTH drilling is limited already in several city centre's, shorelines and other sensitive areas around the world.
Integrated Ring-Bit Systems
Integrated ring-bit systems are designed for drilling straight piles through boulders, rock layers, and even into inclined bed rock.
The heavy-duty ring-bit is integrated in the casing shoe, making it safe to drill in loose ground and water.
PRIMARY APPLICATIONS:
-
End-bearing piles including micro-piling
-
Pilings with sacrificed casings, which have
no large ID ring-bit requirements -
Slope stabilisation
-
Pipe walls, king piles
Solitary Ring-Bit Systems
Solitary ring-bit systems are designed for drilling end-bearing piles through boulders, rock layers, and even into inclined bed rock.
The heavy-duty ring-bit is not attached to the casing shoe, making it the most economical ring-bit solution.
PRIMARY APPLICATIONS:
-
End-bearing piles including micro-piling
-
Pilings with sacrificed casings, which have
no large ID ring-bit requirements -
Slope stabilisation
-
Pipe walls, king piles
Large ID Ring-Bit Systems
Large Inner-Diameter (LID) ring-bit systems are used with sacrificed casings when there is a requirement to continue the hole after the casing is set.
Such casings are left in the ground for economical reasons, corrosion protection, sealing, or dealing with ground cavities.
PRIMARY APPLICATIONS:
-
Piling with sacrificed casings and rock sockets
-
Geothermal and Water Well's
-
Surface Casings (sealing, dewatering)
Drill-Through Systems
Drill-through ring-bit systems combine conventional rock-bit and casing-advancing systems.
Overburden can be drilled with ring-bit set, and then the pilot bit is unlocked from the ring-bit to drill a rock socket without the need to change tools.
PRIMARY APPLICATIONS:
-
Anchoring applications
-
End-bearing piles with rock socket
M-Wall Ring Bit Systems
Solitary M-Wall ring-bit systems are used to drill straight, interlocked casings through boulders, rock layers, or inclined bedrock.
​
With this technique, it’s possible to build interlocked casing walls, roofs, and other structures for the construction industry. M-Wall piles can also replace sheet piles and slurry walls in rocky ground conditions.
​
The heavy duty ring-bit is not attached to the casing shoe, making it the most economical of the ring-bit solutions.
PRIMARY APPLICATIONS:
-
M-Wall pipe-pile walls
-
M-Wall pipe-pile roofs
-
Cofferdams
-
Retaining Walls
-
Water-tight cut-off walls

Horizontal Ring-Bit Systems
Horizontal Ring-Bit Systems are made for horizontal drilling of utility lines. High-friction casings call for a heavy duty ring-bit system.
Drilling under roads and railways requires advanced air control. Thanks to a reliable design, Mincon’s ring-bit system can be used over and over.
PRIMARY APPLICATIONS:
-
Horizontal drilling of utility lines
-
Road & railway underpasses
-
Replacing of concrete culverts
-
HDD surface casings
-
All break through drilling
Forepoling Systems
Forepoling ring-bit systems (also known as tube umbrella systems) are designed to be drilled with a Top Hammer or DTH in an umbrella shape, as secondary support in a tunnel roof, allowing weak ground or overburden to be strengthened by grouting through the casing and grouting valves into the ground.
PRIMARY APPLICATIONS:
-
Forepoling or tube umbrella
-
Anchoring
-
Micro piling
-
Fibre glass face stabilisation
-
PVC foundations
Large Diameter Rock Bits
Mincon's large-diameter rock bits are purpose-engineered for each customers individual requirements. Their concave structure gives them excellent accuracy in challenging jobs with high demands for hole straightness. Mincon's large-diameter rock bits have been used for a variety of applications, including air ventilation for tunnels; shafts for utility lines; rescue shafts for mining, and rock sockets in construction.
-
Large diameter rock bit sizes: 300mm - 1,750mm
-
Supported Shanks: All major shanks and Mincon shanks
Retrievable Ring-Bit Systems
Retrievable ring-bit systems can be reused several times and are designed so that the casing can always be pulled out after drilling.
A large inner diameter allows for the largest rock socket and installed elements.
PRIMARY APPLICATIONS:
-
In-situ piles (skin friction) where casing is fully retrieved
-
Anchoring applications
-
Pre-drilling / temporary casing applications
-
Energy / Water Wells where casing is fully removed
