Rotary Hammers

Rotary hammers are powerful tools designed to handle the drilling and demolition tasks. Whether you're drilling through concrete, or masonry, or performing heavy-duty demolition work, rotary hammers offer unmatched performance and efficiency. Their unique combination of rotational and hammering action makes them ideal for breaking through hard materials, a task that standard drills simply cannot handle. 

Advantages of Rotary Hammers
Rotary hammers are engineered to deliver power and performance compared to traditional drills. The key advantage of a rotary hammer lies in its ability to combine two different actions: rotary motion and hammering action. This allows the tool to drill into tough materials like concrete and masonry with ease, creating holes quickly and efficiently without excessive effort from the user.

The primary benefit of rotary hammers is their impact mechanism, which delivers rapid hammer blows to the material while the drill bit rotates. This hammering action significantly reduces the physical effort needed by the operator, especially when compared to conventional drills. The added impact force enables rotary hammers to break through dense materials like concrete or stone without stalling, providing a much faster and more efficient drilling experience.

Another advantage is the versatility of rotary hammers. Many models come with multiple modes of operation, including drilling-only mode, hammering-only mode, or a combination of both. This flexibility allows users to adapt the tool to a wide range of applications, making it suitable for both light-duty and heavy-duty tasks.

Applications of Rotary Hammers
Rotary hammers are used in a variety of applications, particularly in industries that require drilling or breaking through hard materials. Below are some key areas where rotary hammers excel:

Concrete and Masonry Drilling: 
One of the common applications of rotary hammers is drilling into concrete, brick, and masonry. The powerful hammering action combined with the rotational motion allows rotary hammers to create precise holes in tough materials, whether for anchoring, installing plumbing or electrical systems, or setting up concrete reinforcements.

Demolition Work
Rotary hammers are also used for demolition tasks, such as breaking up concrete floors, removing tiles, or chipping away at walls. Their hammering function makes them more effective than standard drills or impact drivers when dealing with hard materials. Equipped with the right chipping or chiseling attachments, rotary hammers can quickly break down large sections of material with minimal effort.

Construction and Renovation: 
In construction and renovation projects, rotary hammers are invaluable for tasks such as drilling anchor holes, removing old building materials, and creating pathways for utilities. Their ability to efficiently handle heavy-duty tasks makes them a staple tool on job sites where time and precision are critical.

Specialized Applications:
 Some advanced rotary hammers are equipped with features that make them suitable for more specialized tasks, such as core drilling, horizontal drilling, or even drilling through steel-reinforced concrete.

Key Features and Design
Rotary hammers are designed to provide durability and efficiency in demanding environments. Here are some key features that enhance the performance of rotary hammers:

Powerful Motors: 
Rotary hammers are equipped with high-torque motors that provide the power needed to handle tough materials. This ensures faster drilling and minimal strain on the user, even during extended use.

Vibration Control:
 Since rotary hammers can produce substantial vibrations due to the hammering action, many models come with vibration-dampening systems to reduce user fatigue and increase comfort. This feature is especially important when using the tool for long periods.

Multiple Function Modes
Many rotary hammers offer selectable modes of operation, such as drilling, hammering, or a combination of both. This flexibility allows users to tailor the tool to their specific needs, whether it's for drilling precise holes or demolishing hard materials.

Heavy-Duty Construction:
 Built to withstand tough conditions, rotary hammers are made from high-quality, durable materials that can endure high impact, temperatures, and heavy use. Their robust construction ensures that they remain reliable even under demanding tasks.

About Dayu Zhejiang Dayu Electric Tool Co., Ltd.

The company was founded in 1995 and was formerly known as Yongkang Jieaisi Electric Co., Ltd. In June 1999, it was officially renamed Zhejiang Dayu Electric Co., Ltd. In 2004 the company moved from Wuyi Binjiang Industrial Zone to the current Tongqin Town Hardware Machinery Industrial Park. Dayu has always insisted on making double-insulated safe power tools, which is not only the requirement of the national 3C certification but also the quality bottom line of Dayu. At the same time, the design concept of Dayu tools is: to make use of natural resources, give full play to the greatest technical means, and manufacture durable and efficient tools. First, pursue the greatest social benefits, then seek the economic benefits of the enterprise! For this reason, Dayu angle grinders and Dayu electric hammers have always become recognized benchmarks in the industry. Dayu Henggong series angle grinders launched in 2016 combine machinery and electronics. Their working efficiency is 1-3 times that of traditional angle grinders, which greatly improves labor productivity. The company has obtained more than 30 national patents in total and has been rated as a contract-abiding and trustworthy unit for many years. In 2017, it was rated as a Zhejiang Province science and technology-based small and medium-sized enterprise. In 2018, we will apply for Jinhua City and national high-tech enterprises.

The "Quality" column is the large-scale TV documentary column in China with the theme of recording product quality and brand building. Every year, 104 companies from different industries across the country will be selected to participate in the filming. The "Quality" column team began to enter Dayu Company at the end of 2017. After the preliminary review, re-review, and final review procedures, Dayu Company has performed well in the fields of entrepreneurship, innovation ability, and pursuit of good quality, and was officially shortlisted as the only power tool company in the "Quality" column of CCTV Discovery Channel in 2017.
In 2018, the company will further use Henggong products as a breakthrough point, relying on Dayu's more than 20 years user base, vigorously promoting Henggong products, striving for more than 40% of traditional product replacement rate, consolidating Dayu's gold medal quality in the hearts of users, and further expand market share. good

Dayu is determined to become the brand of angle grinders in China and become the quality benchmark of the industry! In the new year, Dayu people will take entry into the "Quality" column as a starting point, make use of CCTV's brand promotion channels, do a good job in quality, and cheer for Made in China 2025! Dayu firmly believes that: adhering to the road of quality is correct, in line with the trend of social development, and in line with the trend of the industry. Dayu's tomorrow will be better!
