In hard rock mining and earthwork projects, blasting operations are restricted by safety regulations and environmental protection standards. Conventional rock breakers suffer from low efficiency and high costs when tackling ultra-hard rock. The launch of the rock drill and splitter (integrated drill-splitter machine) delivers a brand-new industry solution. It combines drilling and splitting procedures into a single excavator attachment to carry out static rock breaking following the “drill first, split later, all-in-one machine” working logic.

Rock Drill and Splitter Vs Separate Driller + Splitting Wedge
1. Labor Cost: Cut Labor Expenses by Half Directly
- Half the staffing requirement: Separate equipment operation is labor-intensive work. It requires one operator for the excavator/driller, plus at least one ground worker to haul, align, and operate the splitting wedge. The excavator rock drill and splitter centralize all controls inside the excavator cab, so only one operator can finish the entire workflow independently.
- Lower hidden labor costs: Ground workers perform high-intensity, high-risk work, which comes with high base salaries and frequent staff turnover caused by fatigue. The excavator rock drill and splitter enables fully unmanned ground work. Companies save costs on workers’ industrial injury insurance, safety management, and recruitment fees for replacing resigned staff.
2. Time Efficiency: Remove Workflow Gaps for Over 30% Higher Productivity
- Eliminate hidden downtime from equipment switching and re-aligning holes: For separate setups, the driller must move away after drilling. Workers then haul hundreds of pounds splitting wedges into position and inserting them into holes, creating long waiting and communication delays. This integrated machine uses mechanical rotation or slide rails on the excavator attachment to switch between drill bit and splitting head within seconds.
- Ultra-fast, highly accurate hole alignment: Manual hole positioning with separate equipment is extremely difficult on steep slopes, high side slopes, or with poor sightlines. Driven by the excavator’s hydraulic arm for precise positioning, the splitting head of the integrated machine mechanically slides straight into the original drilled hole without jamming. It eliminates time wasted re-adjusting for misaligned holes.
- Fast relocation and mobility: When working on scattered hard rock sites over a wide area, separate systems require frequent relocation of multiple devices (air compressors, standalone splitters, excavators), resulting in very low transfer efficiency. This integrated unit adopts a full mounting design: wherever the excavator travels, drilling and splitting functions follow, allowing instant operation upon arrival.
3. Safety & Comprehensive Derivative Benefits
- Zero casualty risks to guarantee uninterrupted construction schedules: Traditional ground workers stand very close to splitting wedges during operation. Flying rock fragments or sudden wedge ejection often lead to severe work injuries, and any safety accident forces a full site shutdown for rectification. This integrated machine lets all staff retreat to safe distances, eliminating injury risks completely and preventing construction delays caused by safety incidents.
What Are the Advantages of Using Rock Drill and Splitter?
The rock drilling and splitting machine delivers value beyond cost savings, with clear improvements in construction quality and operating experience:
- Superior Safety: The machine runs on static hydraulic power without explosives. It fully eliminates blasting hazards, including flying rocks, toxic fumes, and seismic waves. Operators complete all tasks via wireless remote control inside the excavator cab, staying far from danger zones.
- Eco-Friendly Performance: It generates zero vibration, noise, or dust during operation. Construction can proceed without disturbances even in densely populated districts, near hospitals, or beside precision machinery.
- High Precision: Users can pre-set splitting directions, crack shapes, and sizes accurately. Unlike uncontrolled rock fragmentation from blasting, the rock drilling and splitting machine achieves targeted cutting and raises finished stone yield rates.
- Wide Adaptability: Simple single-person operation, easy maintenance, long service life, and convenient transportation.
How Does the Rock Drilling and Splitting Machine Work?
The working principle of the rock drill and splitter can be summed up as “drill first, split later”, with a smooth, continuous workflow: Step 1 – Drilling: The excavator’s hydraulic system powers the rock drill to bore holes of specified diameters (115–152 mm) and depths into rock. Its drilling speed hits 800–1000 mm/min. Equipped with high-torque power heads (3450 N · m for YG-152), it easily bores through ultra-hard rock such as granite and basalt. Step 2 – Rotary Switchover: No excavator repositioning needed after drilling. A rotary mechanism aligns the splitting head perfectly with the pre-drilled hole, solving the common pain point of missing drilled holes with traditional separate tools. Step 3 – Hole Insertion & Splitting: Insert the wedge assembly of the hydraulic splitter into the hole and activate the hydraulic system. Dual-stage splitting cylinders apply synchronized pressure to generate a massive splitting force (thousands of tons for the YG series), splitting rock along pre-planned paths. It features a long, effective splitting stroke with crack widths up to 5.5 cm, fully breaking rock from the base.
Splitting finishes within seconds, supporting non-stop continuous operation. The whole process relies solely on wireless remote control with no manual ground work required.
Unique Strengths of YG Excavator Rock Drill and Splitter
As a professional manufacturer, YG has built exclusive technical advantages across multiple dimensions:
- Lightweight Design & Broad Compatibility: The YG rock drilling and splitting machine features compact size and light weight, compatible with mini excavators as small as 20 tons. Its center of gravity sits behind the excavator’s boom root and stick, preventing forward weight shift and instability during extended or high-lift work. Even on 20-ton small excavators, it delivers stable drilling and splitting at vertical, inverted, and multi-angle positions.
- Multi-Angle Operation Capacity: When the excavator arm stretches or lifts high, the YG integrated rock drill and splitter completes precise vertical and inverted drilling to handle harsh worksites, including high mountain slopes and foundation pit side slopes. It adapts flexibly to jobs without free faces or underground lifting work for metro projects.
- Premium Core Components & Advanced Craftsmanship: It adopts Swedish rock drilling technology with a patented sliding drill frame that features a simple, stable structure, precise positioning, and long service life. Imported splitting wedges processed with advanced heat treatment deliver outstanding durability. An Italian hydraulic booster system balances light weight and powerful performance perfectly.
- High-Efficiency Dust Removal System: Fitted with domestically top-tier screw air compressors that run quietly with a small footprint and low energy consumption. Powerful suction captures dust and rock debris, with high-performance filters enabling dust-free stone mining.
- Far Higher Efficiency Than Traditional Rock Breakers: The working efficiency of the rock drill and splitter is four times that of conventional rock breakers. Rock breakers require hours of repeated hammering on hard rock, while the integrated rock drill and splitter finish drilling and splitting one cubic meter of rock within minutes.
