DKB-502/S-PRO diamond core drill for wet drilling

DKB-502/S-PRO diamond core drill for wet drilling

Description

DKB-502/S-PRO diamond core drill

The perfect solution for wet core drilling
The DKB-502/S-PRO diamond core drill is designed for tough, everyday use in wet core drilling in concrete, stone and masonry. Using the core drill in conjunction with one of our core drilling stands ensures safe and precise results.

Powerful and effortless to use
The 3500-watt electric motor delivers very high torque and is suitable for all tasks up to a maximum drilling diameter of 502 mm. Despite its power, the diamond core drill weighs just 14.2 kg, making it light and easy to handle.

Soft-start function for precise and gentle drilling
The DKB-502/S-PRO diamond core drill features a soft-start function which, by gradually increasing speed and power, offers the following advantages:
  • Reduced start-up load on the machine and the power supply.
  • Better control of the machine and greater precision when starting the drilling process.
  • Torque surges are reduced, making operation safer and more comfortable for the user.
  • A smooth start reduces the risk of cracks and fractures in the material.
Versatile applications
The diamond core drill is fitted with a 3-speed gearbox with oil-bath lubrication and offers idle speeds of 250, 500 and 750 rpm.
The machine’s drill spindle has a 1¼"-UNC external thread for mounting the drill bit.

The diamond core drill is mounted on a core drilling stand via the designated interface. The diamond core drill is compatible with our KBS-502/M-PRO core drilling stand.
The core drill is connected to the water supply on the machine side via a connection nipple (Gardena) with a ball valve.
This allows for optimal adaptation to a wide variety of tasks.

Safety and robustness
  • Safety features: Overcurrent, overvoltage and overheating protection, a carbon brush warning system and a slip clutch ensure the operator’s safety and a long service life for the machine.
  • Intelligent warning system: LED indicators and an LCD display inform the operator of the current operating status and make it easier to monitor the machine. 
  • Sturdy storage case: The plastic case included in the scope of delivery is designedfor the practical and careful storage of the machine and the accessories supplied.

Optional accessories for the DKB-502/S-PRO
To ensure the diamond core drill can be used safely and efficiently, we offer a range of optional accessories specially designed to meet the requirements of professional tradespeople:

KBS-502/M-PRO core drilling stand (Item No. 6215):
The core drilling stand is the perfect complement to the DKB-502/S-PRO core drilling machine and is specially designed for precise and stable drilling work. The core drilling stands are easy to transport yet offer a high degree of stability and precision during drilling work.

WT-60 water tank (Item No. 6270) and WT-60/S with hose reel (Item No. 6274):
The WT-60 water tank or the WT-60/S version with hose reel provide a reliable and flexible water supply for professional use on building sites and in workshops.

Water collection ring (various sizes available):
A water collection ring ensures reliable collection and drainage of water during wet core drilling. The water collection ring must be connected to a wet vacuum.

Experience the impressive technology of the DKB-502/S-PRO diamond core drill and optimise your core drilling operations for maximum precision and efficiency.

Advantages of wet core drilling
Wet core drilling offers several key advantages over dry core drilling:
  • Reduced dust generation:Wet core drilling uses water to cool the drilling area and bind the dust produced. This results in a healthier working environment and less cleaning required.
  • Effective cooling: The cooling effect of the water prevents the drill bit from overheating, thereby extending its service life. Thanks to the constant cooling, drilling can be carried out more quickly and efficiently, as no breaks are required for the bit to cool down. Cooling also reduces the risk of material damage that could result from overheating in the material surrounding the borehole.
  • Higher drilling quality: Wet drilling produces more precise and smoother boreholes, which are required for applications with high precision requirements.
  • Longer drill bit service life: Watercooling results in less wear and a longer service life for the tool, which saves costs. 
  • Reduced noise levels: The wet method is generally quieter than the dry method. The water dampens vibrations and reduces noise during the drilling process.
  • Faster drilling progress: Thanks to lower friction and constant cooling, the wet method allows drilling at higher feed rates and speeds. This means that wet core drilling can usually be completed more quickly than dry core drilling.  
  • Better suited to hard materials: Wet core drilling is particularly suitable for harder materials such as concrete, granite or reinforced concrete, as the cooling and reduced wear make drilling into these hard materials more effective.
  • Versatility of application: The wet method can be used for both vertical and horizontal drilling and is suitable for various materials (concrete, stone, brick).
The wet core drilling method offers numerous advantages, particularly in terms of health and safety, tool life and drilling quality. It is particularly recommended for demanding and precise drilling in hard materials and in dust-sensitive environments.
