Mining Tools Used in Tunnel Excavation and Underground Development
Tunnel excavation and underground development demand mining tools that are powerful, reliable, and built to perform in the most challenging conditions. Whether you are breaking through concrete, brick, or hard rock formations, having the right pneumatic pick hammer can mean the difference between efficient progress and costly downtime. At Mindrill, we supply professional-grade pneumatic tools engineered for exactly these environments.
In this blog, we explore the key mining tools used in tunnel excavation and underground development — and highlight four of Mindrill's most trusted pick hammers, each designed to handle the rigors of underground work with precision and durability.
In tunnel excavation and underground development projects, pick hammers are among the most essential handheld tools on site. They are used for breaking, chipping, and scaling rock and concrete surfaces in confined spaces where larger machinery cannot reach. A good pick hammer must deliver consistent impact force, minimize operator fatigue, and withstand continuous use in dusty, damp underground environments.
Mindrill's pneumatic pick hammers are designed with exactly these demands in mind — featuring air cushioning systems, two-step triggers, ergonomic handles, and quick-change tool retention systems that keep productivity high and downtime low.
MPH09
One of Mindrill's most versatile pneumatic hammers, effective across a wide range of soft/medium to hard materials from brick to concrete.
- Two-step trigger for chisel control
- Air cushioning reduces piston impact
- Comfortable grip, screw-cap retainer
- Kick-latch retainer for quick tool change
- Weight: 10 kg | Impact Rate: 1800 BPM
MPH09S
A versatile two-step trigger pick hammer with air cushioning on both cylinder ends, ideal for soft/medium to hard materials including concrete and brick.
- Two-step trigger maintains chisel point
- Air cushioning on both cylinder ends
- Ergonomic vibration reduction handle
- Kick-latch retainer for quick tool change
- Weight: 12.5 kg | Impact Rate: 1800 BPM
MPH33
Equivalent to the La Cruz ML33, the MPH33 is a versatile pneumatic pick hammer suited for soft/medium to hard rock — from brick through to concrete.
- Two-step trigger for chisel location control
- Air cushioning reduces operator impact
- Comfortable grip, screw-cap retainer
- Kick-latch retainer for quick tool change
- Weight: 5.5 kg | Impact Rate: 2000 BPM
MPH37
Equivalent to the La Cruz ML37, the MPH37 is one of the most commonly used models by professional tradesmen, featuring an efficient pellet distribution system.
- Efficient pellet distribution for consistency
- Lightweight metal handle for reduced fatigue
- Air cushioning system for operator comfort
- Kick-latch retainer for quick tool change
- Weight: 8.5 kg | Impact Rate: 2650 BPM
Selecting the right pick hammer depends on the hardness of the material, the workspace, and the required impact rate. For lighter breaking tasks or tighter spaces, the compact MPH33 at 5.5 kg and 2000 BPM offers excellent maneuverability. For heavier-duty tunnel scaling and concrete demolition, the MPH09S and MPH09 provide robust performance with superior vibration control. For maximum impact rate in professional settings, the MPH37 at 2650 BPM is the go-to choice for experienced tradesmen.
All four models share Mindrill's commitment to operator comfort, featuring ergonomic handles, air cushioning systems, and kick-latch retainers for rapid chisel changes — keeping your crew productive throughout long underground shifts.
