DeWALT FLEXVOLT 60V MAX Cordless Brushless 1-9/16 in. (40mm) SDS Max Rotary Hammer Drill Kit by DeWALT brings true corded-class performance to a fully cordless rotary hammer platform, making it a go-to solution for demanding concrete drilling, anchor installation, and masonry chipping applications. Powered by a brushless motor and delivering up to 6.1 joules of impact energy, this SDS Max combination hammer drives through hard concrete and masonry with speed and efficiency - and because it runs on the FLEXVOLT 60V MAX lithium-ion battery system, there are no cords limiting your reach on the jobsite. With up to 550 RPM and 3,150 impacts per minute, this cordless rotary hammer is purpose-built for professionals who need reliable, high-output performance all day long.

Key Features

• Brushless Motor - eliminates carbon brushes for reduced maintenance and longer tool life compared to brushed motor designs, maximizing uptime on demanding jobsites.
• 6.1 Joules of Impact Energy - delivers fast drilling and chipping even in the hardest concrete, making it well-suited for drilling anchors, fixing holes, and horizontal serial rebar drilling.
• Anti-Rotation E-CLUTCH System - detects a sudden loss of tool control and instantly cuts power, providing enhanced safety during bind-up situations and helping minimize unexpected torque reactions.
• Active Vibration Control - reduces vibration transferred to the user, minimizing fatigue during extended operating periods for greater all-day productivity.
• Three Modes: Rotation Stop, Impact Stop, and Combination - rotation stop mode enables pure chiseling, impact stop mode supports rotary-only drilling with dry diamond cores, and combination mode handles standard hammer drilling - one tool adaptable to multiple tasks.
• SDS Max 1-9/16 in. Keyless Chuck - accepts SDS Max tooling for fast, tool-free bit changes and secure bit retention, supporting holes in concrete, brick, and masonry up to 40mm in diameter.
• Variable Speed Trigger up to 550 RPM - gives the operator precise speed control for different materials and bit sizes, reducing the risk of surface damage on sensitive substrates.
• 3,150 Impacts Per Minute - high blows-per-minute rating translates to faster material removal and shorter drilling times in reinforced concrete and masonry.
• D-Ring Handle with Plastic Housing - ergonomic grip design supports extended use with improved comfort, while the lightweight build reduces operator fatigue during overhead and mid-wall drilling.
• Tag Ready for Tool Connect - enables seamless tracking, management, and control of the tool through the DeWALT Tool Connect system, helping teams manage inventory and reduce tool loss on large jobsites.
• Compact and Ergonomic Design - optimized for horizontal serial drilling and ceiling applications where maneuverability and balance matter most.
• Reversible - forward and reverse rotation extends versatility for bit removal and other applications beyond standard drilling.

Why This Product

• All-day cordless runtime without sacrificing power - the FLEXVOLT 60V MAX platform with two included 9.0 Ah batteries delivers extensive holes per charge, so crews working on large concrete anchor or rebar drilling tasks can stay productive without returning to a power outlet.
• Built-in safety for uncontrolled bind-up situations - the anti-rotation E-CLUTCH system instantly cuts power when tool control is lost, a critical protection feature for operators working with a large-diameter SDS Max rotary hammer where sudden torque reaction poses a real safety risk.
• Reduced fatigue for overhead and extended work - Active Vibration Control combined with a compact, ergonomic design makes this hammer practical for ceiling and upper-wall applications where holding a heavy tool for long periods would otherwise cause rapid user fatigue.
• Multi-mode flexibility in a single tool - with combination hammering, chiseling (rotation stop), and rotary-only drilling (impact stop) modes, this SDS Max hammer replaces the need for multiple specialized tools on a concrete drilling and demolition jobsite.

Frequently Asked Questions

What is the E-CLUTCH system and how does it protect the user?

The anti-rotation E-CLUTCH system is a safety mechanism that detects a loss of tool control - such as a bind-up situation - and reacts by instantly cutting power to the tool. This helps minimize sudden torque reaction that can occur when a large SDS Max rotary hammer encounters an obstruction, providing an added layer of protection compared to standard mechanical clutches.

Are the included batteries compatible with other DeWALT tools?

Yes. The included 9.0 Ah XR FLEXVOLT batteries are part of the 60V MAX FLEXVOLT battery platform. FLEXVOLT batteries are designed to work across compatible DeWALT 20V MAX and 60V MAX tools within the FLEXVOLT system, giving users flexibility across their cordless tool lineup.

What drilling and chiseling modes does the DCH481X2 support?

The DCH481X2 supports three operating modes. Combination mode provides standard rotary hammer drilling for concrete and masonry. Rotation stop mode disables rotation for pure chiseling applications. Impact stop mode disables the hammering function for rotary-only drilling, such as when using dry diamond core bits where impact is not desired.

What is the maximum hole diameter this rotary hammer can drill in concrete and masonry?

This SDS Max rotary hammer is designed for drilling anchors and fixing holes into concrete, brick, and masonry up to 40mm (1-9/16 in.) in diameter, making it appropriate for heavy-duty anchor installation and reinforced concrete applications.
