HILTI DC-SE20 WALL CHASER 110V

Hilti DC-SE 20 Wall Chaser 110V: Precision Channel Cutting for Site Safety

The Hilti DC-SE 20 Wall Chaser 110V is a dedicated and robust electric slitting machine, purpose-built for fast, clean, and productive cutting of channels in a variety of masonry and concrete base materials. Its 110V power configuration makes it the ideal and compliant choice for professional use on construction sites, ensuring safety and performance when installing concealed electrical cables, conduits, or plumbing pipes.

Designed for efficiency and control, the DC-SE 20 provides precise and dust-controlled cutting for a professional finish in walls, floors, and ceilings.

Features

• Dedicated Slitting System:
  • Unlike adapted angle grinders, the DC-SE 20 is purpose-built for chasing, utilizing two parallel diamond blades (typically 125mm diameter) to cut both sides of the channel simultaneously.
  • This design ensures perfectly straight, clean-edged chases, significantly reducing post-cutting clean-up and ensuring a professional finish.
• Optimal Cutting Capacity:
  • Achieves a maximum cutting depth of 40 mm (1.57 inches), allowing for the installation of standard electrical conduits, single pipes, and various cables.
  • Offers an adjustable cutting width of up to 46 mm (1.8 inches), accommodating multiple cables or larger conduits/pipes.
• Powerful 1700W Motor:
  • Equipped with a robust 1700-watt (1.7 kW) electric motor, providing ample power for rapid and efficient cutting through tough materials like concrete, flint, hard stone, brick, and blockwork.
  • Operates at a high no-load speed of 7500 RPM for fast cutting progress.
• 110V Site Compliance:
  • Designed for 110V single-phase operation, making it compliant with health and safety regulations for professional use on UK construction sites (requires connection to a suitable 110V power supply, typically via a 2kVA or 3kVA continuous rated transformer).
• Excellent Dust Management:
  • Features an integrated dust outlet for connection to a compatible Hilti vacuum cleaner (e.g., M-class dust extractor). When properly connected, the system achieves virtually dust-free operation, which is critical for:
    • Protecting operator health from hazardous silica dust.
    • Maintaining a clean work environment, especially in occupied buildings.
    • Improving cutting visibility and efficiency.
• Ergonomic Design & Control:
  • Features an ergonomic handle design that allows for a secure and comfortable grip when working in various positions, reducing operator fatigue.
  • Its weight (approx. 6.9 kg) combined with the two-handle design provides good control and stability during the cutting process.
• Durable Construction:
  • Built with Hilti's renowned robustness, ensuring a long lifetime and reliability even under demanding job site conditions.
  • Equipped with an overload cut-out to protect the motor from damage due to excessive load.
• Ease of Use:
  • Simple and precise cutting depth adjustment.
  • Spacers can be used to set the desired cutting width.

Applications

The Hilti DC-SE 20 Wall Chaser is an essential tool for:

• Electrical Installations: Cutting precise channels for electrical conduits, wiring, and cable runs in concrete, brickwork, and masonry.
• Plumbing Installations: Chasing grooves for water pipes, waste pipes, and heating system pipes to be embedded in walls.
• HVAC Installations: Creating channels for air conditioning lines or ventilation ducts.
• Renovation & Refurbishment: Making clean cuts for new installations or rerouting existing services in various building structures.
• Concealed Fixtures: Preparing walls for the flush mounting of sockets, switches, distribution boxes, and other fixtures.
• Commercial & Residential Projects: Suitable for a wide range of projects where a neat, embedded finish is required.
