MP40-MC: The Geothermal Drilling Powerhouse
Geothermal drilling pushes your DTH equipment to the limit. Hard rock formations and deep holes mean that any delays can cost you a lot of money. This is why you need tools that deliver dependable performance without compromise. The MP40-MC was developed to meet these challenges head-on: a DTH hammer designed to lower your cost of drilling by drilling faster and reducing fuel usage.

Introducing the MP40-MC: Purpose-Built for Geothermal Success
Meet the MP40-MC, Mincon’s latest advancement in down-the-hole hammer technology, designed specifically for the geothermal drilling industry. Engineered to perform in extreme heat and tough geological conditions, the MP40-MC delivers consistent penetration rates and long service life.
Key Features:
-
Designed to reliably deliver high penetration rates at extreme depths
-
Optimised airflow and energy transfer to reduce fuel usage
-
High durability shank design to minimise downtime
Innovations Behind the MP40-MC’s Superior Performance
What makes the MP40-MC stand out? Here are five innovations that elevate its performance:
-
MC Shank Advantage
Mincon’s MC shank design is shorter and wider, allowing for enhanced energy transfer to the rock face while reducing the risk of shanking drill bits.
-
High-Pressure Airflow Design
Maximise your downhole power with Mincon’s proven MP-series internal design, while reducing fuel consumption and operational costs.
-
Wear-Resistant Components
Like all Mincon MP-series hammers, the MP40-MC has internal components that have undergone Mincon’s proprietary heat treatment processes to ensure longer life and precise clearances.
-
Enhanced Energy Transfer
Thanks to an optimised piston-to-bit weight ratio, our engineers have enhanced the energy transfer characteristics of the MP40-MC, making it our most efficient 4-inch DTH hammer to date.
-

Proven in the Field: Trusted by Geothermal Drillers Worldwide
The MP40-MC has already delivered results in real-world geothermal projects, achieving up to 22% higher penetration rates and 24% lower fuel consumption.
-
Improved energy transfer from piston to bit, resulting in faster penetration rates
-
Lower air consumption, thanks to the foot-valveless design of the MC shank
-
Enhanced durability, with a reduced risk of failure
-
Greater overall efficiency, reducing fuel costs and increasing productivity
The MC Shank: Engineered for Longer Life and Easier Maintenance
At the heart of the MP40-MC’s design is the innovative MC shank. This patented shank reduces contact wear, distributes energy more efficiently, and simplifies changeouts in the field. Compared to conventional shanks, the MC shank improves operational uptime while lowering long-term replacement costs.
