Excavator drum cutters are commonly known as excavator rotary cutters, excavator milling heads, or rotary crushers, and are often simply referred to as drum cutters in the industry. Their core function is to use the hydraulic power of the excavator to drive the drum’s rotation, utilizing the wear-resistant cutting teeth on the drum’s surface to cut, crush, and trim hard materials such as rock and concrete. This allows for precise trenching, slope trimming, and rock excavation and is widely applicable in diverse engineering scenarios such as mining, tunneling, and municipal projects. Compared to traditional hydraulic breakers, this equipment offers higher crushing efficiency and greater operational precision, effectively reducing damage to surrounding structures, and is particularly suitable for fine-tuned operations in complex working conditions. It is compatible with excavators of various tonnages. YG, as a professional manufacturer, offers a full range of attachments, including excavator pile breakers, excavator rock saws, and excavator shears, providing efficient solutions for various rock-breaking projects. With reliable quality and customized services, YG has served numerous engineering projects worldwide. If your project also requires excavator attachments to help you complete your project faster, please contact us now.

YG Excavator Drum Cutter Features
- High-Efficiency Rock Breaking, Powerful Performance: Utilizing imported hydraulic motors and planetary gear transmission, the output torque reaches 800-5000 N·m, suitable for rocks of varying hardness (compressive strength ≤150MPa). Cutting efficiency is increased by more than 30% compared to traditional hydraulic breakers, with a daily rock cutting capacity of 200-800 m².
- Wear-Resistant and Durable, Long Lifespan: Hard alloy cutting teeth combined with a high-strength drum body. The cutting teeth can be replaced individually, reducing maintenance costs. The automatic lubrication system and protective devices comprehensively protect core components, resulting in a normal service life of over 3000 hours and a low failure rate.
- Precise Operation, Minimal Damage: The drum-type cutting design allows for precise trenching and slope trimming, with an operating accuracy error of ≤5mm. It effectively controls the crushing range, reducing damage to surrounding rock and building structures, making it suitable for precision work in tunnels, foundation pits, and other applications.
- Multi-Condition Adaptability, Flexible and Convenient: Quickly connects to excavators of different tonnages via an excavator attachment quick coupler, with installation and removal taking only 10 minutes. Supports forward and reverse rotation cutting, accommodating horizontal, vertical, and inclined multi-angle operation requirements.
- Safe and Stable, Easy Operation: Equipped with an overload protection device that automatically shuts down when the load exceeds the rated value, preventing equipment damage. Low vibration and noise during operation (noise ≤85dB) improve the working environment, and operators can become proficient after simple training.
- Customized Adaptation, Functional Expansion: Drum diameter and tooth density can be customized according to excavator tonnage and working materials (rock, concrete, frozen soil). A water spray device can be added for special working conditions to reduce dust and improve environmental protection.
- Compatible and Cost-Effective: Compatible with mainstream excavator brands on the market, requiring no significant modifications to the excavator. Compared to dedicated rock-breaking equipment, the purchase cost is reduced by more than 40%, resulting in substantial overall operating cost advantages.
