Smart Connectivity for Modern Workflows

The DM 400 integrates with Husqvarna’s Embedded Connectivity platform, transforming traditional concrete coring equipment into a smart, data-driven asset. Operators and managers can track runtime, monitor machine health, and schedule maintenance more effectively. Consequently, crews reduce downtime, extend service life, and improve overall project productivity. This forward-thinking design makes the DM 400 more than just a core drill, it becomes a tool that drives smarter business decisions.

Versatility Across Applications

From industrial construction to detailed infrastructure work, the DM 400 handles a variety of coring projects. Its steady torque makes it reliable for reinforced structures, while its compact form supports precision drilling near edges or in confined areas. Furthermore, its compatibility with core stands expands its utility, giving contractors the flexibility to perform both handheld and rig-mounted drilling with ease.

Why Choose the DM 400?

Professionals select the DM 400 because it blends strength, connectivity, and ease of use in one compact system. Its durable construction withstands daily use, while the integrated technology boosts efficiency across multiple projects.
