Hydraulic Hammer Rock Breaker Excavator Attachment
Brand: EastKilowatt. This hydraulic hammer is designed for robust demolition, breaking concrete structures, rocks, and similar materials. It operates using the excavator’s hydraulic system to deliver repeated high-impact blows, improving efficiency on tough jobs. The kit includes essential accessories such as mounting pins, chisels, nitrogen bottles, hoses, and a pressure gauge. Working pressure is listed between 80-110 kg/cm3, with a flow rate of 10-30 L/min and a rate of 500-1200 bpm. Suitable for small excavators from 0.6 to 1 ton.
Excavator Demolition Hydraulic Hammer Breaker for Mini Excavator
Brand: GZWSGHH. This breaker offers a nitrogen hybrid power design to align hydraulic capacity with breaker performance, delivering stronger striking force. Included accessories include a hammer body, mounting pins, chisels, nitrogen bottles, hoses, tool kit, and a pressure gauge. The unit targets mini excavators around 0.6—1 ton and features a similar working pressure and flow rate to optimize performance for demolition, paving, and masonry tasks.
CREWORKS Hydraulic Breaker Hammer
Brand: CREWORKS. This mini excavator attachment includes two chisels and hydraulic hoses, designed for compatibility with smaller machines up to 2 tons. It notes that the nitrogen gas cylinder is empty and requires professional charging prior to use. The breaker supports a 500-1200 impact rate, enabling efficient rock and concrete fragmentation for various demolition tasks.
35mm/40mm Mini Digger Conical Breaker Chisel
Brand: WSPOWERONLINE. Made of toughened steel for wear resistance, this conical breaker tip is designed for general demolition work with penetrative breaking needs. It is compatible with most mini digger breakers that use 35mm/40mm pins. Double-check the pin diameter to ensure a proper fit for your machine. The set typically includes two chisels for quick swaps in field work.
Dexpan Expansive Demolition Grout 11 Lb. Bucket

Brand: Dexpan. Similar in scope to the 11 Lb options, this grout variant supports silent, controlled demolition with easy application steps: Drill, Mix, Pour. It delivers robust 18,000 PSI strength when activated with water and can be used across concrete and rock projects that require quiet operation and reduced vibration.
Dexpan Expansive Demolition Grout 44 Lb. Box
Brand: Dexpan. The 44-lb box extends the same silent demolition approach with three simple steps: Drill, Mix, Pour. It provides expansive strength and crack formation for large-scale rock and concrete removal, suitable for contractors seeking reduced noise and vibration in demolition zones.
Buying Guide: Key Considerations For Rock Breaker Attachments
- Machine compatibility: Verify weight, flow rate, working pressure, and pin size to ensure the attachment fits your excavator and hydraulic system.
- Demolition needs: Choose between traditional hydraulic breakers for immediate impact or non-noise expansive grout methods for sensitive sites.
- Chisels and accessories: Consider included chisels, nitrogen charging capability, hoses, and tool kits. More accessories can save setup time.
- Durability and materials: Look for hardened steel components and robust housings to withstand repeated impacts and harsh environments.
- Maintenance and safety: Ensure proper maintenance guidelines, nitrogen handling where applicable, and safe operation practices for heavy equipment.
- Cost of ownership: Factor in warranty coverage, spare parts availability, and potential downtime for charging or servicing.
- Noise and vibration: For urban or noise-sensitive projects, expansive grout options may offer a quieter alternative to hammer theft.
- Application range: From concrete sidewalks to rock breaking, assess each product’s stated capabilities and recommended operating conditions.
