DeWALT 1-9/16 in. SDS Max Combination Rotary Hammer/Drill Kit brings serious concrete drilling power to demanding jobsite applications. Built around a German-engineered mechanism, this corded electric rotary hammer delivers 6.1 joules of impact energy, making fast work of the hardest concrete, rebar drilling, coring, and chipping tasks. The Active Vibration Control system reduces vibration felt at the handles, so users can work longer with less fatigue - a critical advantage during horizontal serial drilling operations. The complete kit includes a durable carrying case for easy transport between job locations.

Key Features

• 6.1 joules of impact energy - delivers the raw hitting power needed to drill quickly through the hardest concrete, reducing the time spent on tough masonry tasks.
• German-engineered mechanism - a precision-built internal drivetrain designed for durability and consistent, high-performance output in heavy-duty applications.
• Active Vibration Control (Perform and Protect feature) - reduces vibration felt by the user at the handles, limiting fatigue and helping maintain productivity during extended drilling sessions.
• SDS Max chuck system - a keyless, tool-free bit retention design compatible with SDS Max tooling, allowing fast bit changes and a secure lock-up during high-energy impact work.
• 3,150 impacts per minute at 540 RPM - high blow frequency combined with controlled rotational speed gives the hammer excellent penetration rates in concrete and masonry.
• Variable speed with reversible operation - lets the user match drilling speed to material conditions and back out of holes or remove stuck bits without switching tools.
• D-Ring handle design - provides a secure, comfortable grip during horizontal serial drilling, overhead work, and mid-to-upper wall applications.
• Horizontal serial drilling capability - purpose-built to handle repetitive anchor and rebar hole layouts efficiently, saving time on high-volume concrete drilling jobs.
• Thin wall bit compatible - expands application versatility to include thin-wall coring tasks without requiring a separate dedicated tool.
• Packaged kit with carrying case - the included kit box keeps the hammer and accessories organized and protected for easy portability on the jobsite.

Why This Product

• Built for heavy concrete work - with 6.1 joules of impact energy and 3,150 blows per minute, this rotary hammer is sized and powered for demanding mid-to-upper wall and ceiling concrete drilling, not just light-duty masonry tasks.
• Vibration control means longer working time - the Active Vibration Control system directly reduces the vibration transmitted to the user's hands and arms, which translates to less fatigue and more productive hours on the job.
• One tool, multiple modes - the combination hammer/drill design handles rotary drilling, hammer drilling, and chipping in a single unit, reducing the number of tools a crew needs to bring to a concrete application.
• Kit format adds jobsite value - the included kit box means the tool arrives ready to be transported, stored, and protected, rather than requiring the buyer to source a separate storage solution.

Frequently Asked Questions

What type of chuck does the D25481K use, and does it require a key to change bits?

The D25481K uses an SDS Max chuck system. It is keyless, meaning bits can be inserted and removed without a chuck key - a significant time-saver when switching tooling during concrete drilling, coring, or chipping tasks.

Does this rotary hammer have vibration control, and what does that mean for the user?

Yes. The D25481K features Active Vibration Control, which is a Perform and Protect feature designed to reduce the vibration felt by the user at the handles. This directly limits hand-arm fatigue during extended use, allowing for greater productivity on long or repetitive concrete drilling jobs.

Can this hammer be used for chipping and coring, or only for drilling?

The D25481K is a combination rotary hammer/drill, meaning it is designed to handle multiple modes of work. Based on the product data, it supports horizontal serial drilling, coring, and chipping applications - making it a versatile single-tool solution for a variety of concrete tasks.

What power supply does this rotary hammer require?

The D25481K is a corded electric tool that operates at 120 V and draws 10.5 amps. It requires a standard corded power connection, delivering consistent power output without the need for battery charging - well suited for extended on-site concrete work.
