Leopard™ DI550 diesel-powered, down-the-hole (DTH) drill has enhanced mobility, a smaller footprint and can serve multiple sites. Designed for DTH blasthole drilling in mining, quarry and construction industries, it comes with an operator’s cabin, fixed boom, dry dust collector and drill pipe changer.
Low fuel costs
A new Caterpillar C13B engine with lower emissions and compressor pressure control with load sensing feature ensures sustainable and cost-effective drilling.
Robust design and easy maintenance
A modular structure gives easy ground-level access to daily maintenance and service points. Robust design is built to last and adds safety to daily work.
An accurate control system with simple icon displays makes drilling easy. Clear gauges for drilling parameters, compressed air, feed and rotation pressure are some of the features that also guide the operator for more productive drilling.

The modern, overpressurized and ROPS and FOPS-certified ergonomic cabin, with efficient filtration for incoming and recirculating air, excellent visibility and LED lighting – further add to operator comfort.
Efficient dust collector
The efficient dust collector with non-stop cleaning decreases dust emissions into the environment. It also improves filter lifetime and therefore reduces the need for maintenance.
Data collection and TIM3D drill navigation
TIM3D graphical user interface with a 10.4” touch screen gives the possibility to collect production information through My Sandvik Digital Services. It is available as an option and can also be upgraded to a full TIM3D drill navigation system.
