Mighty Seven (M7) cordless drills and hammer drills are designed for demanding drilling and chiseling tasks, while offering versatile use in the workshop and on the construction site. They easily handle drilling into wood, metal, or concrete (thanks to impact modes) and are also suitable for screwing in large screws – always with maximum power, precision, and flexibility. These powerful cordless drills and hammer drills are appreciated by professionals from the ranks of construction workers, fitters, maintenance technicians, and technicians, but thanks to their easy operation and reliability, they will also delight advanced DIY enthusiasts. When working, you are not limited by a power cable or an air hose – M7 tools give you freedom of movement and full power wherever needed, without compromise.

Key technologies and benefits
- Modern 18V Li-ion batteries: All M7 cordless tools use top-of-the-line Li-ion batteries (2.5 Ah or 5.0 Ah), which ensure stable performance and long runtime on a single charge. Batteries also recharge quickly (to 100% capacity in approx. 60 minutes) and do not suffer from the so-called memory effect.
- Brushless motor: Powerful M7 brushless motors provide higher efficiency, lower wear, and longer lifespan compared to conventional brushed motors. By eliminating brushes, they also minimize maintenance requirements and energy loss.
- High torque and two-speed gearbox: M7 drills achieve a tightening torque of up to 90 Nm, allowing them to handle large drill bits and long screws in hard materials. The two-speed gearbox allows switching between higher torque and higher speed – you can always choose the optimal mode for drilling or screwing the given material. It also features adjustable clutch settings (e.g., 23+1) for precise tightening without damaging fasteners.
- Impact drilling and chiseling: The M7 cordless hammer drill is equipped with an SDS-Plus chuck system and offers three operating modes – standard drilling, impact drilling into concrete, and chiseling mode. With an impact energy of 2.6 J, it can handle drilling holes in masonry and concrete (diameters up to approx. 26 mm) as well as lighter chiseling tasks, such as removing tiles or grooving for cables. The Rotation Stop function allows locking rotation during chiseling for safer and more efficient work with the chisel.
- Durable construction and ergonomics: All M7 tools are characterized by robust construction for daily professional use. The 13mm metal chuck on the drills reliably holds drill bits and bit attachments and can withstand high loads. Compact design and balanced weight distribution facilitate handling even in confined spaces or overhead work. Naturally, it includes integrated LED lighting of the work area and rubberized ergonomic grips for a secure hold and operator comfort.
Recommended use in practice
Whether you need to drill holes for anchors in concrete on the construction site or precisely drill into steel profiles in the workshop, M7 cordless drills and hammer drills can handle it with ease. The M7 rotary hammer is especially appreciated by construction and installation technicians for assembling distribution systems, installations, and structures – it enables drilling and chiseling in locations without access to electricity. Similarly, in maintenance or machine assembly, it provides the advantage of cable independence, for example, during field repairs. Cordless drills with high torque are ideal for carpenters and joiners when building wooden structures, where they need to quickly and securely screw together massive elements. Thanks to their compact dimensions, M7 tools can reach even hard-to-access areas and will not disappoint in the home workshop of a demanding DIYer who requires professional precision for every project.
Advantages of Mighty Seven over the competition
Mighty Seven is among the top tool manufacturers that can freely compete with the most well-known brands of power tools. M7 tools excel in robust construction and long lifespan – they are developed with an emphasis on daily professional use in demanding conditions. At the same time, they offer high performance while maintaining an advantageous price/performance ratio, so you get top quality for a reasonable investment. M7 also comes with a unique solution: using a special adapter, their cordless tools can be powered by batteries from other manufacturers, which increases variability and saves costs – if you already own 18V batteries from competing brands, you can use them with Mighty Seven tools thanks to the adapter.
