THE VARIABLE ONE


GRUNDOCORE 1500/650

THE VARIABLE ONE

PERFORMANCE FEATURES

  • Application of crowned bore heads with a max. diameter of 1500 mm
  • Great cutting depth of 650 mm
  • Strong torque of 2320 Nm
  • Crowned bore heads for asphalt and concrete cover layers
The GRUNDOCORE1500/650 core drill unit complements the keyhole technology with circular walk-in excavation pits of up to 1,500 mm in diameter. Especially with sewer rehabilitation methods, this technique has turned out to be very economical and highly productive. The GRUNDOCORE1500/ 650 offers optimal ease of operation and is easy to transport despite the large crowned bore head due to its compact frame design.
  • 01. Flange for crane connection and forklift reception very easy transportation
  • 02. Infinitely variable adjustment of the rotational speed and thrust force the optimal drilling parameters are maintained
  • 03. Use of different crowned bore heads possible diameter range: 800 - 1500 mm
  • 04. Crowned bore head guide stabilisation of the crowned bore head for spot drilling
  • 05. 3 hydraulic vertically adjustable pedestals (300 mm) simple alignment of the core drill unit
  • 06. Wireless remote control control of the drilling process from an optimal and safe position
  • 07. Output signal for activation of external flushing pump adapt flushing volume to drilling process
  • 08. Non-wearing swivel minimal maintenance effort
  • 09. Easy to dismantle panelling sheets safety shutdown for maximum safety at work
