Cordless Hammer Drill Sourcing Młotowiertarka 3851CA

The Sourcing Młotowiertarka 3851CA cordless hammer drill combines a 20V battery platform with 2.2 J impact energy to deliver portable drilling and light chiselling performance. Designed for users who need mobility without mains power, this rotary hammer balances power and ergonomics: a compact body, cushioned handle and straightforward controls support prolonged use on construction, renovation and maintenance tasks. The tool accommodates common drill bits and accessories for wood, metal and masonry work and is intended for both trade and home projects.

Advantages

The cordless design eliminates the need for a power outlet and increases working range while the 20V battery provides sustained power for moderate drilling and impact operations. The 2.2 J impact energy enables efficient penetration in masonry and concrete for common fastening and anchoring tasks. An ergonomic grip and balanced weight distribution reduce operator fatigue during longer jobs, and simple control layout makes mode selection and speed control intuitive. The compact size improves access in confined spaces compared with larger corded rotary hammers.

Suitable for

• Drilling holes in concrete, brick and stone for anchors and fasteners
• Drilling and driving in wood and metal for assembly and carpentry
• Light chiselling or demolition tasks where controlled impact is required
• On-site repair, renovation and maintenance work without immediate access to mains power

Key specifications

• Power source: 20V rechargeable battery
• Impact energy: 2.2 joules
• Operating modes: drilling, hammer drilling (rotary hammer) and screwdriving
• Ergonomic handle with cushioned grip for reduced vibration transmission
• Compact, lightweight housing for better access in tight spaces

How to use

Charge the compatible 20V battery fully before first use and install it according to the tool’s instructions. Select the appropriate drill bit or chisel for the material and secure it in the chuck. Choose the correct operating mode for the task (rotary hammer for masonry, standard drilling for wood/metal, or screwdriving) and set the speed or torque as required. Use a steady, controlled feed pressure—let the tool’s impact action work rather than forcing it. For repetitive or deeper holes, periodically withdraw the bit to clear debris and avoid overheating. After use, remove the battery and store the tool and accessories in a dry place.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling masonry. Match drill bit type and size to the material, and avoid prolonged continuous operation to prevent overheating. For heavier demolition or large-diameter drilling, consider a higher-capacity rotary hammer.
