Husqvarna Construction DM 400 Core Drill Electric
Product Overview
The Husqvarna Construction DM 400 is a powerful corded electric core drill motor designed for medium- to heavy-duty drilling in concrete and similar construction materials. With a 3.2 kW motor, three-speed gearbox, and a maximum drilling capacity of 350 mm (14 in.) when mounted on a drill stand, it is built for demanding professional applications where controlled drilling and high productivity are important.
The DM 400 features a durable aluminum motor housing and protective carrying handle for easier handling on the jobsite. It can be paired with a compatible Husqvarna drill stand, such as the DS 500, for guided drilling and adjustable drilling angles.
Key Features
3.2 kW electric motor: Provides substantial power for medium- and heavy-duty core drilling.
350 mm maximum capacity: Supports core drilling up to 350 mm (14 in.) when used with a suitable drill stand.
Three-speed gearbox: Offers optimized spindle speeds for different drilling diameters and materials.
Durable aluminum housing: Designed to withstand demanding jobsite handling.
Ergonomic carrying handle: Makes transportation and positioning easier while providing additional motor protection.
Load indicator: LED indicators help the operator monitor machine load and maintain an efficient drilling pressure.
Elgard™ overload protection: Uses pulsation to warn the operator when the motor is approaching an overload condition.
Smart Start®: Reduces spindle speed by half to make starting a hole easier.
Quick connection: Simplifies mounting the drill motor to a compatible drill stand.
Quick-release washer: Helps make removal of the drill core bit more convenient.
Embedded Connectivity: Provides machine data and health insights through Husqvarna's connected-machine system on applicable variants.

Husqvarna's technical documentation lists the DM 400 at 3,200 W rated power, with three operating gears and a maximum concrete drilling diameter of 350 mm. Electrical ratings vary by regional version, so the voltage and current should be verified against the specific article number before purchase.
Drilling Performance
The DM 400 uses three optimized spindle speeds to accommodate different core-bit diameters. Husqvarna's published data gives full-load speeds of approximately 230, 460, and 720 rpm, allowing the operator to select a suitable gear for the drilling application.
For concrete drilling, Husqvarna specifies an operating range of approximately 55–350 mm (2–14 in.), with the maximum 350 mm diameter applying when the motor is mounted on an appropriate drill stand.
Compatible Drill Stand
The DM 400 is designed for stand-mounted core drilling and can be connected quickly to a compatible stand. Husqvarna lists the DS 500 as a compatible drill stand. With the DM 400 and the appropriate spacer configuration, the DS 500 provides a maximum drilling diameter of up to 470 mm (18.5 in.) for the stand itself; however, the DM 400's own rated maximum drilling diameter remains 350 mm (14 in.).
This distinction is important when selecting accessories: the stand may have a higher physical capacity than the drill motor.
Professional Applications
The DM 400 is suitable for a variety of construction and installation tasks, including:
Concrete core drilling
Horizontal drilling
Vertical drilling
Angled drilling
Water evacuation openings
Ventilation openings
Pipe and cable penetrations
Stair-rail and fence installations
Stitch drilling for larger openings
Drilling close to corners
Protection and Operator Control
The Elgard™ system helps protect the motor against excessive loading by providing a pulsating warning as an overload condition approaches. The integrated load indicator provides visual feedback, allowing the operator to adjust drilling pressure and maintain productive operation.
The Smart Start® function reduces the spindle speed by approximately half when beginning a hole. This makes it easier to establish the initial drilling position before returning to normal operating speed.
Why Choose the DM 400?
The Husqvarna DM 400 is a strong choice for contractors who require a high-powered electric core drill motor with stand-mounted capability. Its three-speed gearbox, 350 mm drilling capacity, overload protection, load monitoring, and durable construction make it suitable for demanding concrete drilling work.
Its quick stand connection and ergonomic design also make it practical for crews that regularly move between different drilling applications. When paired with the appropriate Husqvarna drill stand and diamond tooling, the DM 400 provides a controlled setup for accurate, professional core drilling.
Note: The DM 400 is sold in different electrical configurations for different markets. Confirm the required voltage, frequency, current rating, article number, and local electrical requirements before ordering. Maximum drilling capacity also depends on the drill stand, core bit, material, mounting method, and operating conditions.
