When you' re working with hard materials like concrete or stone, choosing the right tool can make a huge impact on your efficiency and results. From SDS rotary hammers and SDS Plus rotary hammer drills to SDS Max rotary hammers and cordless rotary hammer drills, each tool is designed for specific tasks and applications. Knowing the differences among these tools—and the best uses for each—will help you make an informed decision, ensuring that your investment supports your toughest projects. In this guide, we' ll cover what sets each type apart, when to use each tool, and how to keep them in peak condition.
A rotary hammer is a high-powered tool made for heavy-duty tasks, capable of drilling through dense materials such as concrete, stone, and masonry. Equipped with an advanced impact mechanism, rotary hammers can handle rigorous drilling and chipping applications with ease. These tools are available in various configurations, including corded rotary hammers for consistent power and cordless rotary hammers for improved portability.
A hammer drill (sometimes called an impact drill) is a lighter-duty tool often used for tasks like drilling into brick, masonry, or tiles. While it doesn’t have the same intense power as a rotary hammer, a hammer drill is ideal for smaller or less demanding tasks. Hammer drills are commonly available in both corded rotary hammer drill and cordless rotary hammer drill formats, which gives users flexibility based on their needs and the project location.
Rotary Hammer: A cordless rotary hammer or electric rotary hammer drill typically provides more consistent and robust power, essential for heavy-duty tasks. The impact force in these tools, especially SDS Max rotary hammers, is much higher, making them a great choice for chiseling or demolition work.
Hammer Drill: The power output of a hammer drill is adequate for lighter applications, such as drilling through drywall or light masonry. Cordless options, like the cordless rotary hammer drill, are ideal for portability but offer less impact force than rotary hammers.
Rotary Hammer: Using a piston-driven mechanism, rotary hammers provide a stronger impact, especially in SDS rotary hammers and SDS Max rotary hammers. SDS (Slotted Drive System) models, including SDS Plus rotary hammers, allow bits to lock into place, ensuring stability and efficient operation.
Hammer Drill: Relies on a mechanical cam-action mechanism, providing less impact force. Hammer drills work well with standard drill bits for lighter tasks but don’t match the precision or power of a rotary hammer.
Rotary Hammer: Generally heavier, rotary hammers such as the cordless SDS rotary hammer or electric SDS Plus rotary hammer are bulkier due to their higher power components. SDS Max rotary hammers, built for intense demolition tasks, are the heaviest in this category but ideal for concrete and masonry.
Hammer Drill: Light and compact, hammer drills are easier to handle. Models like the cordless rotary hammer drill are especially popular for smaller tasks around the house or for situations where lightweight equipment is essential.
Select a rotary hammer for:
Concrete Foundations: Large-diameter holes in concrete are best tackled with SDS Max rotary hammers or electric rotary hammers.
Masonry Walls: For drilling and chiseling through brick or stone, an SDS Plus rotary hammer drill or SDS Max rotary hammer is best.
Demolition Work: With a chisel-only mode, rotary hammers such as cordless SDS rotary hammers can break up tough materials like tile or concrete slabs.
Opt for a hammer drill for:
Light Masonry Tasks: Smaller tasks, like drilling into brick or wood, are best suited for lighter tools such as cordless rotary hammer drills.
DIY and Home Projects: A cordless rotary hammer drill offers portability and is ideal for general-purpose household use.
Light Materials: Hammer drills are great for drilling through drywall, soft wood, and light masonry without the need for extreme power.
Rotary hammers work with specialized drill bits like SDS, SDS Plus, and SDS Max. These bits are designed to lock securely in the chuck, preventing slippage and ensuring stability during intense impact.
The original SDS bit system was developed for light masonry work, providing a secure connection between the bit and the rotary hammer. This design introduced the slotted drive concept, which prevents slippage and ensures efficient energy transfer from the hammer to the bit. However, standard SDS bits are less common today, as SDS Plus and SDS Max have largely replaced them for more specialized tasks. SDS rotary hammers are perfect for light-duty drilling projects and shallow holes in softer masonry.
SDS Plus is the most widely used type of SDS bit, particularly popular among professionals and DIYers alike. Designed for moderate-duty tasks, SDS Plus bits have a shank diameter of 10mm, which provides a snug fit and secure locking mechanism in SDS Plus-compatible rotary hammers. This system is ideal for jobs that require efficient drilling into concrete, brick, and other dense materials. SDS Plus rotary hammers are typically smaller and more lightweight, making them ideal for both indoor and outdoor applications.
SDS Max bits are the go-to choice for heavy-duty, professional-grade tasks. These bits are designed with a larger 18mm shank diameter, allowing them to handle the high torque and impact power of large rotary hammers. SDS Max rotary hammers are built for the toughest jobs, including chiseling and breaking up concrete. The SDS Max system also provides an even stronger bit-hammer connection, ensuring optimal energy transfer for maximum drilling depth and speed.
Hammer drills are generally compatible with standard drill bits, available in a variety of sizes for wood, masonry, and metal. For improved results on masonry tasks, consider using SDS rotary hammer drill bits designed for moderate materials.
To ensure your rotary hammer performs at its best:
Clean After Each Use: Remove dust to prevent clogging. Rotary hammers, like electric rotary hammers and cordless SDS rotary hammers, require regular cleaning due to their intense usage.
Lubricate Key Parts: Periodically apply lubricant to keep the internal piston mechanism smooth and efficient.
Inspect for Wear: Check for any signs of wear on the chuck or SDS bit holder, especially with high-impact models like SDS Max rotary hammers.
To keep a hammer drill functioning well:
Remove Debris: Keep dust out of your corded rotary hammer drill and cordless rotary hammer drill to extend their service life.
Secure Loose Parts: Regularly inspect for loose screws or components.
Lubricate: Lightly oil the chuck and other moving parts for smooth operation.
Rotary hammers and hammer drills each play vital roles in drilling and demolition work. For intense tasks, an SDS Max rotary hammer or SDS Plus rotary hammer provides the required power. For lighter work, a cordless hammer drill or corded rotary hammer offers versatility without the added weight.
