Hammer drill STHOR T79054 620W SDS Plus — rotary hammer for drilling and chiselling

STHOR T79054 is a 620W hammer drill with an SDS Plus chuck engineered for drilling and light chiselling in masonry, concrete and comparable building materials. The tool combines rotary drilling and percussion action to create and widen holes for anchors, pipes and cable entries, and to perform occasional small demolition or renovation tasks. Its compact design and SDS Plus interface support rapid bit changes and compatibility with common SDS Plus accessories.

Advantages

The hammer drill offers a balanced 620W motor that delivers sufficient power for standard installation and repair jobs while maintaining manageable weight and size. The SDS Plus chuck provides secure bit retention and fast replacement without additional tools. Due to its rotary and hammering modes, the unit handles both drilling and light chiselling, reducing the need for multiple tools. The compact form factor improves handling in confined spaces and over-head applications.

Suitable for

• Drilling holes for wall anchors and fixing systems in masonry and concrete
• Creating openings for electrical conduit, plumbing pipes and cable routing
• Light chiselling tasks such as removing plaster, tiles or mortar
• General maintenance and renovation work in residential and small commercial settings

How to use

Select an appropriate SDS Plus bit for the required hole diameter and material. Secure the bit in the SDS Plus chuck until it locks. Set the tool to the desired mode — rotary with percussion for drilling in concrete or masonry, rotary-only for non-percussive drilling. Hold the drill firmly with both hands, align the bit with the marked drilling point and start at low speed to establish the hole, then increase speed and apply steady, moderate pressure. For chiselling, switch to hammering mode and use controlled short passes. After finishing, allow the tool to cool, remove the bit and clean dust from the chuck and vents.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and a dust mask when drilling or chiselling. For extended drilling in reinforced concrete, use carbide-tipped SDS Plus bits and allow periodic breaks to prevent overheating. Ensure workpieces are properly supported and check for hidden utilities before starting. Store the drill and accessories in a dry environment to maintain performance.
