The DeWALT 1-1/8 in. SDS Plus Rotary Hammer Kit is a corded electric hammer drill engineered for professionals who need to complete large diameter holes through the hardest concrete with speed, control, and reduced physical strain. Powered by an 8.5-amp motor at 110V, this SDS-Plus rotary hammer delivers 3.5 joules of impact energy and up to 5,200 blows per minute, making it a reliable single-tool solution for demanding concrete drilling, anchoring, and light chipping applications. The kit includes a portable carrying case for convenient jobsite transport, and the tool is compatible with the DWH304DH Onboard Dust Extractor for OSHA Table 1 Compliant dust control.

Key Features

• 3.5 joules of impact energy - drives through hard concrete quickly, reducing drilling time and operator effort on tough materials
• Durable German-engineered hammer mechanism - precision-built internal components deliver consistent hammering performance over the long life of the tool
• SHOCKS Active Vibration Control technology - actively reduces vibration felt at the D-handle and auxiliary handle, lowering user fatigue during extended use and increasing daily productivity
• Wide optimal drilling range between 3/16 in. and 7/8 in. - covers the most common anchor and fastener hole sizes in concrete, making this a versatile single-hammer solution for professional crews
• Variable speed trigger up to 1,100 RPM - allows precise hole starting and speed adjustment to match the material, reducing bit wander and improving accuracy
• Factory-set clutch - automatically disengages the drive when the bit jams, reducing sudden high-torque kickback reactions that can strain the wrist or arm
• OSHA Table 1 Compliant dust extraction compatible - when paired with the DWH304DH Onboard Dust Extractor, helps meet silica dust exposure regulations on the jobsite
• Reversible operation - forward and reverse modes add versatility for bit removal and light demolition tasks
• Optimized ergonomic D-handle design - provides excellent tool control in overhead, horizontal, and vertical drilling orientations, reducing operator strain throughout the workday
• Keyless SDS-Plus chuck - allows fast, tool-free bit changes to keep work moving without interruption
• Accompanying kit box - keeps the rotary hammer protected and organized for easy transport between job sites

Why This Product

• For contractors drilling large diameter anchor holes in concrete all day, the combination of 3.5 joules of impact energy and SHOCKS Active Vibration Control means faster hole completion with measurably less fatigue compared to a standard rotary hammer without vibration management technology.
• The wide 3/16 in. to 7/8 in. optimal drilling range means one tool handles the full spectrum of common concrete anchor sizes - eliminating the need to carry multiple hammer drills on site.
• Dust compliance is built into the design: compatibility with the DWH304DH Onboard Dust Extractor enables OSHA Table 1 compliance for respirable crystalline silica, helping contractors meet regulatory requirements without separate rig setups.
• The factory-set clutch and variable speed trigger work together to give operators consistent control in tight spaces and awkward angles - reducing the risk of bit jams causing injury or workpiece damage when drilling overhead or into confined areas.

Frequently Asked Questions

What is SDS-Plus and why does it matter for concrete drilling?

SDS-Plus is a chuck system designed for rotary hammers that uses a slotted shank to lock bits securely while still allowing them to slide axially during hammering. This design transfers impact energy more efficiently into the material than a standard keyless chuck, and it enables tool-free bit changes - so you can swap between drill bits and chisels quickly without stopping to find a chuck key. The D25333K uses an SDS-Plus keyless chuck with a 1-1/8 in. capacity.

Is this rotary hammer compatible with OSHA Table 1 dust control requirements for silica?

Yes - when the D25333K is paired with the DeWALT DWH304DH Onboard Dust Extractor (sold separately), the combination delivers OSHA Table 1 Compliant dust extraction. This helps contractors meet federal respirable crystalline silica exposure regulations when drilling into concrete, masonry, or similar materials.

What does the factory-set clutch do, and when does it activate?

The factory-set clutch is a safety mechanism that reduces sudden, high-torque reactions if the drill bit binds or jams in the material. When the bit stops unexpectedly - such as when it hits rebar or a void - the clutch disengages the drive rather than transferring that rotational force to the operator's hands and wrists. This significantly lowers the risk of wrist strain or loss of control during concrete drilling.

What is the maximum drilling capacity of this rotary hammer in concrete?

The D25333K has a maximum drilling capacity of 0.875 in. in concrete, 1 in. in wood, and 0.5 in. in steel. The optimal SDS-Plus drilling range in concrete is between 3/16 in. and 7/8 in., which covers the most common anchor hole sizes used in commercial and residential concrete work - making this a practical single-hammer solution for most drilling applications on site.
