Rotary Hammer STHOR T79049, SDS, 500W, 2 functions

STHOR T79049 is a rotary hammer with an SDS chuck and a 500W motor designed for light to medium masonry and concrete tasks. It offers two operating modes — rotary drilling and hammer drilling — enabling efficient hole making for anchors, wiring, fixtures and general renovation work. The compact design and SDS system provide faster bit changes and consistent impact performance for typical DIY and professional repair jobs.

Advantages

The STHOR T79049 combines a 500W motor with an SDS chuck to deliver reliable power and convenient tool-changing for masonry work. Two operating functions allow switching between rotary drilling and hammer drilling to match the task. Its compact construction reduces user fatigue during extended use while maintaining stable impact action suitable for small to medium concrete and brick applications.

Suitable for

• Drilling holes for anchors and plugs in concrete and masonry
• Installing electrical wiring and plumbing fixtures
• General renovation and repair work on brick and concrete surfaces
• Light to medium demolition tasks where controlled hammering is required

Key specifications

• Motor power: 500 W
• Chuck system: SDS
• Operating modes: 2 functions (rotary drilling, hammer drilling)
• Intended material: masonry and concrete (light to medium work)
• Design: compact for reduced user fatigue

How to use

Select the appropriate SDS drill bit for the material and secure it in the SDS chuck until it locks. Choose the required operating mode depending on whether you need rotary drilling or hammer drilling. Hold the tool firmly with both hands, align the bit with the intended drilling point, and apply steady pressure while allowing the tool’s impact action to penetrate the material. For larger holes, start with a smaller pilot bit if needed and progress to the final diameter. Follow standard safety precautions such as wearing eye and ear protection and securing the workpiece.

Usage recommendations

Use the rotary hammer with correctly sized SDS bits and appropriate protective equipment. For sustained drilling in dense concrete, allow intermittent pauses to avoid overheating. When switching between functions, ensure the bit is fully inserted and the selector is engaged before resuming work.
