When comparing prices, you must look beyond the sticker price and evaluate the Drilling Depth (m) and Hole Diameter (mm) capabilities. Ensure the machine features a high-torque hydraulic system and a robust mud pump or air compressor compatibility. For instance, a machine priced for 200m depth should ideally have a lifting force of at least 15-20 tons to handle heavy drill pipes. Always verify if the price includes essential accessories like drill rods, bits, and hoses, as these can add 20-30% to the total cost if purchased separately.
