High-Impact Rotary Hammers and SDS Hammer Drills for Professionals

Rotary hammers are designed for professionals who need powerful, efficient and durable tools for demanding drilling and chiselling applications. Whether you need precision drilling in masonry or high-impact chiselling in concrete, Hilti offers a range of corded and cordless rotary hammers to meet every jobsite requirement.

What Are Rotary Hammers?

Rotary hammers are power tools designed for drilling into tough materials such as concrete, stone, and masonry. Unlike standard drills, they use a piston-driven hammer mechanism that delivers higher impact energy, making them ideal for heavy-duty applications.

Introducing SDS (Slotted Drive System) Hammer Drills

SDS drill technology increases drilling efficiency by providing better bit retention and reduced slippage. Hilti rotary hammers use the SDS-Plus and SDS-Max systems, offering compatibility with a wide range of drill bits for different applications.

Types of Rotary Hammers Available at Hilti

Hilti offers a wide range of power tools designed to meet the needs of different types of professionals.

Corded Rotary Hammers

Hilti's corded rotary hammers deliver consistent power for long drilling and chiselling applications. Designed for heavy-duty construction, they offer superior drilling speed, reduced vibration and increased durability.

Cordless Rotary Hammers

For flexibility and mobility on the jobsite, Hilti's Nuron battery platform powers cordless rotary hammers that deliver cord-level performance without being tethered to a power source. These tools feature extended run time, fast charging and high efficiency brushless motors.

SDS-Plus vs. SDS-Max Hammer Drills

Selecting the right rotary hammer depends on the scale and intensity of your drilling or chiselling task. While both the SDS-Plus and SDS-Max systems offer superior performance compared to standard drills, they are optimised for different levels of impact energy and material hardness. Understanding their differences will ensure you choose the best tool for your specific application.

• SDS-Plus Hammer Drills: Best for light to medium duty drilling in concrete and masonry, commonly used for anchor holes.
• SDS-Max Hammer Drills: Designed for heavy-duty applications, offering greater impact energy for larger diameter drilling and chiselling.

Why Choose Hilti Rotary Hammers?

• Advanced vibration reduction: Hilti’s Active Vibration Reduction (AVR) minimizes user fatigue, allowing for longer operation times without compromising comfort.
• Precision control and variable speed settings: Hilti rotary hammers offer adjustable speed settings and precision controls that enhance accuracy across various materials and applications.

FAQs

How do I choose between SDS-Plus and SDS-Max rotary hammers?

SDS-Plus systems are ideal for light to medium duty drilling, typically accommodating drill bits up to 30 mm in diameter. They are often used for tasks such as installing anchors. SDS-Max systems, on the other hand, are designed for heavy-duty applications, accepting larger drill bits and providing greater impact energy, making them suitable for extensive drilling and chiselling in hard materials.

What safety features should I look for in a rotary hammer?

Modern rotary hammers are often equipped with safety features such as Active Torque Control (ATC), which prevents the tool from rotating uncontrollably if the drill bit is jammed, and Active Vibration Reduction (AVR), which reduces operator fatigue by minimising vibration.

Can I use a rotary hammer for chiselling?

Yes, many rotary hammers have a chiselling function that can be used for tasks such as removing tiles or creating channels in concrete. It's important to use the correct chisel attachments and ensure the tool is set to the correct mode to avoid damage.

What maintenance is required for a rotary hammer?

Regular maintenance includes checking and replacing worn brushes, lubricating moving parts as specified in the operator's manual and checking the power cord for signs of wear. Keeping the tool clean and storing it properly will also extend its life.

Why is my breaker not delivering full power?

Reduced performance can be caused by a number of factors including worn internal components, poor lubrication or power supply problems. It's advisable to consult the user manual for troubleshooting steps or contact a professional service centre for assistance.
