How to choose
Shank Compatibility
The primary requirement when selecting jackhammer bits is ensuring the shank matches your specific power tool. The supplied options include SDS Max shanks, which are designed for rotary hammers like the DCH273B, and 1-1/8 inch hex shanks for larger demolition breakers. Using an incompatible shank will prevent the bit from seating correctly or locking into the tool chuck, rendering the equipment inoperable. Always confirm your hammer’s receiver type before purchasing to avoid mismatching hardware.
Bit Geometry and Purpose
Select the bit shape based on the specific demolition task at hand. Moil point bits, such as the 20-inch hex hammer steel, are intended for breaking up concrete or heavy materials. Scaling chisels, like the 12-inch by 2-inch SDS Max model, are engineered for removing surface material or leveling. For specialized tasks like digging in clay or gravel, a clay spade provides the necessary surface area to move earth efficiently, while wide tile chisels are optimized for floor surface demolition.
Length and Reach
Bit length influences both leverage and the ability to reach specific depths. Longer bits, such as the 20-inch moil point or 17-inch clay spade, offer extended reach for deep digging or vertical breaking tasks. Shorter bits, like the 12-inch scaling chisel, provide increased control and power transfer for surface-level work. Consider the depth of the material you are removing to ensure the bit provides adequate clearance without sacrificing structural stability during operation.
Material Construction
High-quality jackhammer bits are constructed from alloy or hardened steel to withstand the high-impact forces generated by demolition hammers. These materials are chosen for their durability and resistance to the intense stresses encountered when striking hard substrates like concrete, stone, or packed soil. When reviewing product descriptions, prioritize steel construction to ensure the bit can endure repeated impacts without premature deformation or failure. Proper material selection is essential for maintaining consistent performance over the lifespan of the tool.
Tool Integration
A jackhammer bit is only as effective as the power tool driving it. While bare tools like the 20V MAX SDS Rotary Hammer Drill (DCH273B) provide the necessary motor power, the bit must be compatible with the hammer's application modes. Ensure your hammer has the appropriate energy ratings to drive your chosen bit size. Matching the bit's weight and design to the hammer’s impact energy ensures optimal demolition efficiency and protects the tool's internal components from excessive vibration or strain.
Frequently asked questions
Can I use an SDS Max bit with a 1-1/8 inch hex hammer?
No, SDS Max bits and 1-1/8 inch hex shank bits are designed for different hammer chuck systems. The SDS Max shank is specific to rotary hammers like the DCH273B, while the 1-1/8 inch hex shank is engineered for heavier demolition breakers. Because these connection types have different diameters and locking mechanisms, they are not interchangeable. Always verify your hammer's chuck specification before choosing your bit to ensure proper fit and safe operation.
What is the best bit for digging in hard soil or clay?
For digging in materials like clay, gravel, adobe, or sandstone, a clay spade bit is the most effective choice. For example, the Firecore 4-1/2 inch by 17 inch SDS Max clay spade is specifically designed for these gardening and landscaping tasks. The wide shovel shape allows you to break through packed earth more efficiently than a standard point or chisel bit, which are intended primarily for breaking concrete or masonry rather than moving soil.
Are these bits compatible with all DeWalt rotary hammers?
Compatibility depends on the specific shank type required by your rotary hammer. The DCH273B 20V MAX SDS Rotary Hammer Drill is designed for SDS Max accessories. However, not all rotary hammers use SDS Max; some smaller models may use SDS Plus or other specific chuck sizes. Always check your tool’s manual or the product specifications for the DCH273B to confirm that the shank of the bit you are purchasing is fully compatible.
What is a moil point bit typically used for?
A moil point bit, such as the HS2161 20-inch hex hammer steel, is primarily used for heavy-duty demolition and breaking tasks. The pointed tip concentrates the hammer's impact energy onto a very small area, making it highly effective for cracking concrete, stone, or breaking up asphalt. It is generally the go-to bit for starting a demolition project where you need to penetrate a hard surface before switching to a wider chisel for material removal.
How do I choose between a scaling chisel and a tile chisel?
A scaling chisel, like the DW5837 12-inch by 2-inch bit, is designed for general surface removal and leveling concrete. A wide tile chisel, such as the 4-inch wide tile bit, is specifically optimized for prying up floor tiles and stone. The tile chisel’s extra width provides better coverage for lifting flat materials off a substrate, whereas the scaling chisel is better suited for removing mortar, rust, or excess concrete from a surface.
Bottom line
When selecting the right bit, matching your specific power tool's chuck system is the most critical step. For users with SDS Max rotary hammers like the DCH273B, the DW5837 12-inch scaling chisel is an excellent choice for surface work, while the Firecore 4-1/2 inch clay spade is the superior option for landscaping and digging. If you are operating a heavy-duty demolition breaker with a 1-1/8 inch hex receiver, the HS2161 20-inch moil point offers the necessary reach and durability for concrete breaking. The 4-inch wide tile chisel is the clear standout for specialized floor demolition. Each bit is built from robust steel, ensuring that your choice is governed primarily by the task's material and your hammer's connection type.
Deciding which bit to purchase requires a clear assessment of your project requirements. First, identify your hammer's shank size—SDS Max or 1-1/8 inch hex—to narrow your options. Second, define the material you are working on; use moil points for breaking concrete, clay spades for digging, and scaling or tile chisels for surface removal. By focusing on the interaction between the bit geometry and the substrate, you can ensure the tool performs efficiently. Always prioritize bits constructed from high-strength alloy or hardened steel to ensure longevity, and verify that your tool's power capacity aligns with the demands of the specific bit selected.
