A drilling & splitting excavator attachment combines rock drilling and hydraulic splitting in one excavator-mounted system. It first drills holes into rock or concrete and then uses a hydraulic splitter to create controlled cracks and break the material into manageable sections.
Unlike blasting, this method produces lower noise and vibration and allows operators to work in urban areas, confined sites, and other locations where conventional rock breaking may be restricted.

One Attachment for Drilling and Rock Splitting
Traditional rock splitting often requires separate drilling and splitting equipment, which can increase handling time and labor requirements.
YG’s excavator rock drilling and splitting machine integrates both operations into one attachment. The excavator provides the hydraulic power while the attachment handles hole drilling and controlled splitting.
How It Works?
- Drill holes into the rock or concrete at the required positions.
- Insert the hydraulic splitter into the drilled holes.
- Apply hydraulic splitting force to create controlled cracks.
- Break the material into sections that can be removed by the excavator.
This process is suitable when controlled fracturing is required and blasting is impractical or undesirable.
Key Benefits of hydraulic rocl drilling and splitting machine
1.Drilling and Splitting in One System
The integrated design allows drilling and splitting operations to be performed with the same excavator, reducing the need to move separate machines between work areas.
2.Controlled Rock Breaking
Hydraulic splitting applies force directly inside pre-drilled holes, allowing operators to control where cracks develop and progressively break large rock or concrete sections.
3.Low Noise and Vibration
Compared with blasting and some conventional breaking methods, hydraulic splitting generates significantly less noise and vibration, making it suitable for urban construction, infrastructure projects, and restricted work areas.
4.Excavator-Mounted Design
The attachment is designed to work with a 25-ton excavator in the standard configuration. The mounting system can be customized according to the excavator model and hydraulic specifications.
5.Remote or Cab Operation
Depending on the configuration, the machine can be operated by remote control or from the excavator cab.
Applications of the Excavator Drilling & Splitting Attachment
This rock drilling and splitting excavator attachment can be used where large rocks, concrete structures, or hard ground need to be fractured in a controlled manner.
Typical applications include:
- Rock excavation in restricted construction sites
- Foundation excavation
- Trenching through hard rock
- Road and infrastructure construction
- Concrete structure demolition
- Quarry and stone processing
- Urban excavation
- Work near existing buildings and infrastructure
The attachment is particularly useful when controlled rock breaking with reduced vibration is more important than high-impact demolition.

Drilling & Splitting vs. Conventional Rock Breaking
| Method | Drilling & Splitting Attachment | Blasting | Hydraulic Breaker |
|---|---|---|---|
| Controlled cracking | High | Medium | Medium |
| Noise | Low | High | High |
| Vibration | Low | High | Medium–High |
| Drilling required | Yes | Yes | No |
| Suitable for restricted areas | Yes | Often restricted | Depends on site |
| Excavator integration | Yes | No | Yes |
| Large rock mass breaking | Yes | Yes | Yes |
The right method depends on rock hardness, material size, site access, required production rate, and local working restrictions.

FAQs about Drilling & Splitting All-in-one Machine
1.What is a drilling and splitting excavator attachment?
A drilling and splitting excavator attachment is a combined system that uses an excavator to drill holes and hydraulically split rock or concrete. It is designed for controlled material fracturing without relying on blasting.
2.What excavator is required?
The standard configuration is designed for a 25-ton excavator. The final matching requirements depend on the excavator’s hydraulic flow, working pressure, mounting dimensions, and available hydraulic circuits.
3.How large are the drilled holes?
The standard drilling system supports hole diameters of approximately 43–115 mm, with a maximum drilling depth of about 1700 mm.
4.How long does splitting take?
Under suitable working conditions, the listed configuration can complete a splitting operation in approximately 3 minutes. Actual time depends on rock type, hardness, hole spacing, material size, and operating conditions.
5.Can the attachment be customized?
Yes. YG can customize the mounting system and configuration according to the customer’s excavator model and project requirements.
6.Is a dust removal system available?
Yes. A dust removal system can be added when required, which can be useful for dry drilling and dust-sensitive working environments.
