Husqvarna Construction DM 406 H Hydraulic Core Drill
Product Overview
The Husqvarna Construction DM 406 H is a hydraulic core drill motor designed for demanding professional drilling applications where high power, durability, and controlled operation are essential. Unlike conventional electric core drills, it uses an external hydraulic power source, making it well suited to locations where electrical equipment is impractical or where a hydraulic power pack is already available.
The DM 406 H is designed primarily for stand-mounted core drilling and can handle core diameters up to approximately 350 mm (14 in.), depending on the drilling configuration. Its hydraulic drive provides strong torque and reliable performance for drilling in concrete, brick, and other masonry materials.
Key Features
Hydraulic-powered design: Uses hydraulic power rather than an electric motor, making it suitable for demanding jobsite environments.
High drilling capacity: Designed for core drilling applications up to approximately 350 mm (14 in.) with a suitable stand and tooling.
Three-speed gearbox: Provides different spindle-speed ranges to match the core diameter and drilling conditions.
High torque output: Hydraulic drive is well suited to large-diameter and heavy-duty core drilling.
Stand-mounted operation: Designed for controlled drilling using a compatible drill stand.
Water-cooled drilling: Supports wet core drilling for cooling the diamond bit and managing drilling debris.
Overload protection: Helps protect the drive system when excessive drilling pressure is applied.
Robust construction: Built for professional use in demanding construction environments.
Quick coupling: Hydraulic connections allow the drill to be connected to a compatible hydraulic power source.

Specification note: Hydraulic flow and pressure requirements can vary according to the specific DM 406 H configuration and hydraulic power source. Always verify the machine's identification plate and current Husqvarna technical documentation before selecting a power pack.
Hydraulic Power System
The DM 406 H is designed to operate from a suitable hydraulic power source rather than a conventional electrical outlet. This configuration can be particularly useful for construction environments where electric equipment presents practical limitations.
A properly matched hydraulic power pack supplies the required oil flow and pressure to drive the drill motor. Correct hydraulic flow is important because it affects spindle speed and overall drilling performance.
Before operation, the hydraulic power source should be matched to the manufacturer's specified flow and pressure requirements. Hydraulic hoses, couplings, and connections should also be rated appropriately for the operating pressure.
Three-Speed Gearbox
The three-speed transmission allows the operator to select a suitable operating range according to the diameter of the core bit and the drilling material.
Lower gearing is appropriate for larger core diameters where greater torque is required, while higher gearing can be used for smaller-diameter drilling. Selecting the correct gear helps maintain efficient diamond cutting performance and prevents unnecessary loading of the hydraulic system.
Professional Core Drilling Applications
The DM 406 H is suitable for applications such as:
Concrete core drilling
Masonry drilling
Pipe penetrations
Cable openings
Ventilation openings
Plumbing installations
Water evacuation holes
Horizontal drilling
Vertical drilling
Angled drilling
Large-diameter core drilling
Construction and infrastructure work
Stand-Mounted Operation
The DM 406 H is intended for use with a suitable drill stand rather than ordinary handheld drilling. A rigid stand provides the necessary support for larger core diameters and allows the operator to control the feed rate and drilling angle.
Stand mounting is particularly beneficial when drilling large or deep holes where maintaining alignment is important. The complete setup should be securely anchored or mounted according to the requirements of the specific drilling application.
Wet Drilling
The DM 406 H is designed for wet core drilling, where water is supplied to the drilling area to cool the diamond tooling and help carry drilling debris away from the cutting zone.
Adequate water flow is important during wet drilling. The correct water supply helps control bit temperature and supports efficient cutting, particularly when working with large-diameter cores or hard concrete.
Why Choose the DM 406 H?
The Husqvarna Construction DM 406 H is a strong choice for contractors who require a hydraulic core drill for heavy-duty, stand-mounted drilling. Its hydraulic drive eliminates the need for an integrated electric motor, while the three-speed gearbox provides flexibility across different core sizes.
It is particularly well suited to demanding construction and infrastructure projects where hydraulic power is readily available or where a hydraulic drilling system offers advantages over conventional electric equipment.
Important Considerations
The DM 406 H is a professional hydraulic machine and requires a properly matched hydraulic power source. The drill should not be connected to a hydraulic system that exceeds the manufacturer's specified pressure or flow requirements.
Actual drilling capacity and performance depend on the hydraulic power source, drill stand, core bit, concrete or masonry type, drilling depth, water supply, and operating conditions. Always confirm the exact specifications for the regional model and follow Husqvarna's operating, hydraulic, and safety instructions before use.
