What to Consider Before You Buy
To help you make the right choice, focus on these three key areas:
Parts & Service Support: The availability of spare parts and technical support in your region is critical. Premium brands like Epiroc and Sandvik have extensive global dealer networks. Woserld also offers growing international support.
Rock Hardness & Hole Depth: For extremely hard rock or deep holes (>15m), the high-frequency COP 2238AW+ or the deep-hole optimized A22L/D are strong choices. For general purpose drifting in medium-hard rock, the A22D is a very efficient and cost-effective option.
Integration vs. Component: Decide if you want a fully integrated jumbo from a single manufacturer or if you plan to mount a drill component onto an existing carrier.
To help you narrow down the options, what is the expected rock hardness (e.g., MPa) for your project and the required drilling depth?
