Why Choose a DTH Drilling Rig for Rock Boring?

1. Superior performance in hard rock: Ideal for granite, basalt, and quartzite;
2. Deeper, straighter boreholes: Reduces deviation, ideal for water wells and foundation drilling;
3. Modular and mobile: Most rigs are crawler-mounted and easily transported;
4. Cost-effective operation: Lower maintenance, longer service life.

These advantages make DTH rigs a top choice for contractors and developers worldwide.

Understanding DTH Drilling Machine Price Factors

When investing in a DTH machine, understanding the DTH drilling machine price is critical. The cost varies based on :

1. Drilling depth and hole diameter requirements;
2. Engine power and fuel efficiency;
3. Air compressor capacity (air pressure & consumption);
4. Brand and customization (e.g., crawler chassis, automation options).

YG Machinery offers factory-direct pricing and supports global shipping. We can help tailor configurations to suit your project’s exact demands.

FAQ:

Q1: What’s the difference between a DTH rig and a top hammer drill? A1: DTH rigs place the impact piston directly at the bottom of the hole, leading to straighter, deeper, and more efficient drilling, especially in hard rock.

Q2: What compressor size is needed for your DTH rigs? A2: It depends on the model. For example, the YGK300 requires working pressure: 1.7–2.5 MPa (2.2 MPa recommended). airflow capacity: 20–26 m³/min, type recommendation: Mobile diesel screw air compressor or high-pressure electric air compressor for construction sites.

Q3: Can the machine drill through granite or basalt? A3: Yes. All YG DTH rigs are designed for hard formations including granite, limestone, and basalt.
