K 4000: Versatile, Low-Maintenance Cutting with Electric Precision

The K 4000 from Husqvarna is a highly versatile electric concrete saw designed for professionals who need efficient, deep concrete cutting with minimal maintenance and operating costs. As part of Husqvarna’s renowned power cutter lineup, the K 4000 is ideal for both indoor and outdoor applications, offering quiet operation, zero emissions at the point of use, and smooth control during flush cuts, window openings, and other precision tasks.

Engineered for productivity and control, this saw is a go-to solution for contractors working in residential, commercial, and renovation environments where ventilation and accuracy are critical.

Cut-n-Break Technology for Deep, Controlled Cutting

What sets the K 4000 apart is its innovative Cut-n-Break method. This unique cutting approach allows users to achieve a cutting depth of up to 16 inches (400 mm) from one side using dual 9-inch blades. The system works by making successive cuts in a groove, breaking off sections as you progress. This not only allows for deep penetration but also helps minimize the risk of overcutting, making it ideal for applications like window and door openings where clean corners are required.

Compared to traditional methods, this technique offers lower tool cost, reduced wear on equipment, and extended blade life, positioning the K 4000 as a smart, economical choice for serious contractors.

Flush Cutting and Indoor Applications Made Easy

Because the K 4000 is electrically powered, it produces no direct exhaust emissions, making it suitable for enclosed spaces and indoor projects. It’s perfect for flush cutting close to floors or walls, thanks to its slim blade design and ergonomic build. Whether you’re removing wall sections, making precise slab cuts, or working on restoration projects, this concrete saw delivers the flexibility you need.

Its low vibration and balanced weight distribution further enhance operator comfort, especially during extended use.
