Rotary hammer NAC HE-SDS-LI-20V 20 V — cordless SDS drill/hammer, HE-SDS-LI-20V

The NAC HE-SDS-LI-20V is a 20 V cordless rotary hammer designed for drilling and light chiselling in concrete, masonry and similar materials. This cordless SDS drill/hammer combines a compact, mobile design with impact drilling and hammering modes to support construction and renovation tasks where a power cable is impractical. The tool accepts SDS-compatible bits and is intended for both professional tradespeople and DIY users who need mobility and straightforward operation.

Advantages

The cordless design removes the constraint of a power outlet and enables work in confined or remote locations. SDS compatibility ensures fast and secure bit changes and reliable performance with standard masonry bits. The combination of impact drilling and hammering modes allows the same tool to perform drilling in reinforced concrete and light chiselling tasks, reducing the need for multiple tools. The compact form factor improves handling during overhead or tight-space operations.

Suitable for

• Drilling holes in concrete and masonry for anchors and fasteners
• Light chiselling and removal of plaster or tile adhesive
• Installation and renovation work on construction sites without ready access to mains power
• DIY projects requiring portable impact drilling

Key specifications

• Power supply: 20 V cordless
• Chuck system: SDS-compatible
• Operating modes: impact drilling and hammering (chisel)
• Intended material: concrete, masonry and similar substrates
• Use class: suitable for professional and DIY applications

How to use

Select the appropriate SDS bit for the task and insert it according to the tool's SDS locking mechanism until it is securely seated. Set the operating mode to either impact drilling for boreholes or hammering for chiselling, and adjust speed or impact settings if available. When drilling, support the tool with both hands, apply steady pressure without forcing, and allow the hammer action to do the work. For chiselling, use controlled short bursts and reposition the tool as required. Always remove the battery before changing accessories or performing maintenance.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. Choose SDS masonry bits sized for the anchor or dowel being installed, and allow the battery to cool between extended heavy-duty tasks. For continuous heavy chiselling in reinforced concrete, consider a corded or higher-power hammer to maintain productivity.
