HILTI DHC300 DIAMOND CUTTER

Hilti DCH 300 Diamond Cutter: Precision & Power for Demanding Cuts

The Hilti DCH 300 Diamond Cutter is a professional-grade electric handheld cutting tool engineered for high-performance and precise cuts in the toughest construction materials. With its robust motor, optimized ergonomics, and advanced features, it delivers exceptional productivity and safety, whether you're working on reinforced concrete, granite, brick, or steel. Its capability for both wet and dry cutting, coupled with superior dust management, makes it an indispensable asset on any modern job site.

Features

• Deep Cutting Capacity:
  • Utilizes a 305 mm (12 inch) diamond blade.
  • Achieves a maximum cutting depth of 120 mm (5 inches). This is significantly deeper than conventional 230 mm angle grinders (which typically cut around 60 mm), allowing for single-pass cuts through many common wall and floor thicknesses.
• Powerful Electric Motor:
  • Features a high-output motor, typically rated around 2300W (input power).
  • Provides consistent power for smooth and efficient cutting through very hard materials, even under heavy load.
  • No load RPM: 4900 rpm.
• Wet and Dry Cutting Capability (DCH 300-X):
  • The latest DCH 300-X models come standard with an integrated water kit, allowing for both wet and dry cutting.
  • Wet Cutting Advantage: Water cools the diamond blade, extending its life and preventing overheating. It also significantly reduces dust (virtually dust-free operation), making the cutting process healthier, cleaner, and often up to 30% faster than dry cutting.
  • Dry Cutting Advantage: For situations where water use is not feasible, the DCH 300 can still be used dry, especially when connected to a compatible dust extractor.
• Optimized Ergonomics & Control:
  • Push-Style Cutting / Inverted Blade Rotation: Unlike most angle grinders, the blade rotates in a way that guides the tool away from the operator's body. This "push" operation on its wheels makes the cutter easier to control, allowing for perfectly perpendicular cuts and enhancing safety by moving the blade away from the user.
  • Low Vibration: Designed to minimize vibration levels (e.g., 5.1 m/s²), reducing operator fatigue and increasing comfort during prolonged use.
  • Depth Gauge: A built-in depth gauge allows for precise control of the cutting depth in 10 mm steps, ensuring accurate and consistent cuts from 40 mm to 120 mm.
• Advanced Safety and Durability Features:
  • Protection Systems: Equipped with protection against overheating, overloading, and water (for wet cutting), prolonging the tool's lifetime and increasing operator safety.
  • Oil-Bath Gearing: Optimized gearing for cutting work, ensuring long-term reliability.
  • Automatic Restart Interlock: Prevents accidental restart after a power interruption.
  • Dust Extraction Outlet: Integrated dust extraction outlet in the blade guard ensures a virtually dust-free job site when used with a compatible Hilti vacuum cleaner.
• Robust Build Quality: Hilti tools are known for their exceptional durability and rugged construction, designed to withstand the harshest job site conditions.
• 110V Operation: Available in 110V versions, making it suitable for UK construction site compliance (requires a 32A plug for full power).

Applications

The Hilti DCH 300 Diamond Cutter is an indispensable tool for a wide array of demanding cutting applications, including:

• Concrete & Masonry Cutting: Cutting reinforced concrete, granite kerbstones, slabs, brick, and masonry blocks.
• Opening Creation/Extension: Cutting and extending openings for windows, doors, shafts, and ducts in concrete and masonry walls.
• Controlled Demolition: Making precise preliminary cuts for controlled demolition work.
• Metal Cutting: Cutting metal beams, steel pipes, and reinforcing bars (rebar).
• Renovation & Refurbishment: For precise cuts when modifying existing structures, especially indoors where fume-free electric operation is preferred.
• Utility Work: Cutting trenches and openings for pipes and cables.
