How to choose
Drive System Compatibility
When shopping for DeWalt SDS bits, first identify if your tool requires SDS-Plus or SDS-Max shanks. SDS-Plus bits, like the DW5440 or the DWAF5403, are designed for lighter-duty rotary hammers. Conversely, SDS-Max bits such as the DW5813 feature larger, more robust shanks engineered for heavy-duty demolition and large-diameter drilling tasks. Always match the shank style to your specific rotary hammer chuck to ensure a secure fit and optimal power transfer. Using the incorrect shank type can prevent the bit from seating properly or lead to potential tool damage during operation.
Bit Diameter and Length
Select the appropriate bit diameter and length based on your specific masonry project requirements. DeWalt offers a variety of sizes, ranging from 3/16-inch diameter bits for smaller anchors to 3/4-inch diameter options for heavy-duty applications. Length is equally critical; ensure the bit is long enough to reach your target depth, such as the 36-inch total length provided by the DW5813, or the 18-inch length of the DW5440. Choosing the right dimensions prevents unnecessary tool strain and ensures you can complete the hole in a single pass without needing extensions.
Application-Specific Designs
Consider the cutting geometry of the bit for the material you are drilling. The DW5813 is specified as a 4-cutter bit, which is optimized for drilling through difficult aggregate or reinforced concrete. Standard SDS-Plus bits like the Rock Carbide DW5440 are well-suited for general masonry work. For high-volume projects, bulk sets like the 25-pack of DWAF5403 bits offer convenience and replacement efficiency. Matching the bit's cutting head design to the hardness of the brick, cement, or stone ensures better performance and a cleaner hole finish in tough materials.
Bare Tool vs. Bit Sets
If you are starting a new project, evaluate whether you need a standalone rotary hammer like the DCH273B or a comprehensive bit set. The DCH273B provides the 20V MAX cordless power required to drive these bits, featuring three distinct application modes for versatility. If you already possess a compatible drill, focus on purchasing specific bit packs or multi-piece sets. Bundled sets provide a range of diameters for various tasks, while bulk packs of single-size bits are ideal for repetitive installation tasks, such as setting multiple masonry anchors in a single day.
Material Durability
Look for carbide-tipped construction, which is the industry standard for masonry bits. Products like the 8-piece SDS-Plus set utilize carbide tips to resist wear when drilling through abrasive surfaces like stone, brick, and cement. The Rock Carbide tip found in the DW5440 is specifically engineered to maintain its edge under the high-impact force of rotary hammers. Investing in high-quality carbide construction prevents premature dulling, ensuring the bits maintain their cutting efficiency over time, even when consistently used against the demanding resistance of cured concrete or natural stone.
Frequently asked questions
Can I use an SDS-Plus bit in an SDS-Max rotary hammer?
No, SDS-Plus and SDS-Max systems are not interchangeable. SDS-Plus bits, such as the DW5440 or the DWAF5403, have a smaller shank diameter than SDS-Max bits like the DW5813. Attempting to force an SDS-Plus bit into an SDS-Max chuck will not provide a secure fit and will prevent the hammer drill from functioning safely or effectively. Always confirm the specific chuck capacity of your tool before selecting your drill bits.
What is the benefit of a 4-cutter bit like the DW5813?
A 4-cutter bit is engineered to provide a more consistent and round hole, particularly when drilling through challenging materials like reinforced concrete or dense masonry. Because it features four cutting edges rather than two, it helps reduce vibration and minimizes the chance of the bit binding or getting stuck if it encounters steel rebar. This design is highly advantageous for heavy-duty applications requiring larger diameter holes where precision and stability are essential for success.
How do I know if the DCH273B rotary hammer is compatible with my bits?
The DCH273B 20V MAX SDS rotary hammer is designed for use with SDS-Plus shank bits. You can use any standard SDS-Plus bit, such as the DW5440 or the bits included in the 8-piece SDS-Plus set, with this tool. It is not compatible with SDS-Max bits, which require a larger, industrial-grade rotary hammer. Always check the tool's manual or product specifications to verify the shank type it supports before purchasing bits.
Are the 25-pack DWAF5403 bits suitable for heavy demolition?
The DWAF5403 bits are 3/16-inch diameter SDS-Plus bits, which are primarily intended for drilling pilot holes or setting smaller masonry anchors. They are not designed for heavy-duty demolition work, which typically requires larger, more robust bits like the 4-cutter DW5813. For demolition tasks, you should utilize tools and bits specifically rated for high-impact breaking and material removal rather than these smaller-diameter drilling bits, which are better suited for fastening and anchoring applications.
What materials can the 8-piece SDS-Plus set drill through?
The 8-piece SDS-Plus carbide rotary hammer drill bit set is designed for use on masonry materials including brick, cement, stone, and concrete. The inclusion of carbide tips helps the bits maintain performance when facing these abrasive surfaces. While these are versatile for general masonry installation, always ensure you are using a drill with the correct SDS-Plus chuck and appropriate speed settings for the specific density of the material you are currently drilling.
Bottom line
The strongest configuration for heavy-duty masonry work is pairing an SDS-Max tool with a specialized 4-cutter bit like the DW5813. This combination is specifically engineered to handle the high torque and impact forces required for drilling through tough, dense concrete or reinforced materials. For general-purpose and anchoring tasks, the SDS-Plus system remains the gold standard, with the DW5440 Rock Carbide bit offering excellent durability for standard-sized holes. When stocking a workshop, opting for the 8-piece SDS-Plus set ensures you have a versatile range of diameters for various fasteners, while the 25-pack of DWAF5403 bits provides a cost-effective solution for high-volume, repetitive anchoring work on professional job sites.
Deciding between these options depends entirely on your project scale and existing equipment. If you are performing large-scale demolition or drilling deep, large-diameter holes, invest in SDS-Max components for their robust shank and multi-cutter efficiency. For everyday fastening, light construction, and masonry drilling, the SDS-Plus platform is significantly more manageable and efficient. Always verify the chuck type on your rotary hammer before purchasing, as the shank style is the most critical factor for safety and compatibility. If your workload involves repetitive tasks, prioritize bulk packs to ensure you have fresh, sharp bits on hand to keep your workflow moving without interruption.
