On construction sites near buildings, in urban areas, inside tunnels and at heritage sites, blasting is simply not an option. The vibration, fly rock and noise from controlled blasting can damage adjacent structures, disturb residents and violate environmental regulations. Yet traditional hydraulic breakers are slow and inefficient on large, hard rock formations. An integrated rock drill and splitter solves this dilemma by combining two separate processes — drilling and hydraulic splitting — into a single excavator-mounted attachment that completes the entire rock breaking cycle without blasting.
The hydraulic rock drill and splitter works in two sequential stages. First, the drilling unit bores a clean, precise hole into the rock face. Then, without requiring the operator to switch attachments or bring in a second machine, the splitting unit extends into the drilled hole and applies powerful hydraulic force to split the rock along controlled lines. The entire process is fully static — no vibration, no fly rock, no loud noise and no toxic fumes.
This two-in-one design eliminates the downtime associated with moving between a separate drill rig and a standalone splitter, and it means a single excavator operator can handle the complete rock breaking workflow from the cabin. YG manufactures these rock drill and splitter attachments in multiple configurations to match different excavator sizes and project scales.

7 Applications of Integrated Rock Drill and Splitter
The YG series integrated rock drill and splitter serves multiple industries.
- Mining Operations. In mining, it is commonly used for secondary breaking, block extraction, and selective mining where precision is essential. It helps reduce ore dilution and improves material recovery rates. The clean fractures preserve the integrity of the ore body.
- Quarrying and Dimension Stone Extraction. For dimension stone extraction, the integrated rock drill and splitter enables clean splitting of stone blocks, preserving material quality and reducing waste. Unlike blasting, which can micro-fracture the stone, the splitter produces clean, usable blocks.
- Urban Demolition and Excavation. In city environments, hydraulic rock drills and splitters are essential for foundation excavation, basement construction, and road cutting. They allow controlled rock removal without damaging nearby structures or disturbing the public.
- Tunneling and Underground Engineering. Tunnel and underground engineering projects benefit greatly from this equipment. The low vibration characteristics help maintain tunnel stability and protect existing support structures.
- Hard Rock Mining. The integrated rock drill and splitter excels in hard rock mining, handling granite, basalt, and other tough formations. Two-stage splitting cylinders provide double pressure boost for ultra-hard rock, delivering high splitting efficiency and large output.
- Foundation Excavation. Building foundations often require removing rock without damaging adjacent structures. The precision control of the integrated drill and splitter makes it ideal for foundation work in tight urban sites.
- Reinforced Concrete Demolition. The hydraulic rock drill and splitter is frequently used in demolition work, particularly for breaking reinforced concrete structures where controlled cracking is required.
5 Advantages of Integrated Rock Drill and Splitter
1. Drill and split integrated on one frame
The single biggest advantage is the integration of both functions on one attachment frame. Separate drilling and splitting requires two machines, two operators and significant downtime for equipment positioning and handover. The integrated design lets one operator on one excavator complete the full cycle, which reduces labor costs, cuts equipment idle time and simplifies project logistics.
2. Fully static, vibration-free rock breaking
Unlike blasting and hydraulic hammer breaking, the splitting process generates no impact vibration. The rock is pushed apart by steady hydraulic force rather than shattered by repeated impacts. This means there is no risk of vibration damage to adjacent buildings, tunnels, pipelines or underground utilities — a critical factor for urban construction and renovation work near existing structures.
3. Controlled splitting direction and block size
The operator controls the orientation of the splitting wedge, which determines the direction in which the rock will break. By planning hole positions and wedge orientations in advance, the operator can produce rock blocks of predictable size and shape. This is especially valuable in stone quarrying, where regularly shaped blocks command higher market value, and in demolition work where controlled block size makes material handling and removal easier.
4. No fly rock, no noise, no environmental restrictions
Blasting creates fly rock, dust, loud shockwaves and toxic fumes, which typically requires securing a large exclusion zone and obtaining special permits. Hydraulic hammers produce loud impact noise and significant dust. The integrated splitter produces none of these — it operates quietly, with no flying debris and minimal dust. This means it can be used in areas where blasting and hammer breaking are prohibited or restricted, including residential zones, hospital vicinities, school zones and protected environmental areas.
5. Simple operation by existing excavator crew
The attachment connects to the excavator’s standard auxiliary hydraulic circuit and is controlled from the cabin using the existing joystick and foot pedal controls. Operators who are already experienced with excavator-mounted attachments can learn to use the machine quickly, without requiring specialized drilling or blasting certifications. This means contractors do not need to hire specialized crews — their existing excavator operators can run the equipment.
