A rotary hammer's power is only as good as its connection to the bit. This is where the Slotted Drive System, or SDS, comes in. SDS is a specialized chuck and bit design that allows the bit to slide back and forth while rotating, maximizing the impact energy from the tool's piston mechanism. The two most common types, SDS-Plus and SDS-Max, are not interchangeable, and understanding their differences is crucial for matching the right tool to the job.
The SDS-Plus system is the most widely used and is designed for general-purpose professional tasks.
How it Works: SDS-Plus bits have a 10mm shank with two open grooves and two closed grooves. The open grooves allow the bit to slide forward and backward within the chuck, letting the hammer mechanism hit the back of the bit directly. The closed grooves lock the bit in place, preventing it from falling out while still allowing for that essential piston-like movement.
Best for These Tasks:
Light to Medium Drilling: It's the standard for drilling holes up to 1 inch in diameter in concrete, brick, and block. This includes common tasks like installing anchors, running electrical conduit, or hanging fixtures.
Light Demolition: With a chisel bit, an SDS-Plus rotary hammer can handle tasks like chipping away tile, removing plaster, or breaking up small sections of concrete.
Key Characteristics:
Size: Smaller and lighter than SDS-Max tools.
Versatility: Excellent for a wide range of common tasks.
Impact Energy: Typically in the 2-4 joule range.
The SDS-Max system is built for the most demanding applications where brute force and large-scale performance are required.
How it Works: SDS-Max bits have a larger, 18mm shank with three open grooves and a locking segment. This bigger, more robust design is built to withstand significantly higher torque and impact forces. The locking segment ensures the bit remains securely in the chuck even under the most extreme pressure, while the grooves enable the powerful hammering action.
Best for These Tasks:
Heavy-Duty Drilling: This is the tool for drilling large-diameter holes (over 1 inch), core drilling, or drilling deep into reinforced concrete.
Serious Demolition: The high impact energy and larger bits make it a perfect choice for breaking up concrete floors, trenching, and other extensive chipping applications.
Key Characteristics:
Size: Larger, heavier, and more powerful than SDS-Plus tools.
Durability: Built for sustained use on industrial and heavy construction sites.
Impact Energy: Typically over 10 joules, providing the force needed for demolition and large-scale drilling.
