Description

Diamond core drill: DKB-202/H-PRO

The perfect solution for wet and dry processing
The DKB-202/H-PRO diamond core drilling machine has been developed for tough everyday use and impresses with its high performance and reliability. It is ideal for core drilling in reinforced concrete or concrete in wet cutting as well as for dry processing of sand-lime brick, masonry, clinker or brick. The core drill can be used in manual mode or with a core drill rig.

Powerful and effortless to use
The electric motor with an output of 2200 watts ensures a very high torque and is suitable for all tasks up to a maximum drilling diameter of 162 mm (in manual mode) or 202 mm (with core drill rig). Despite its high performance, the diamond core drill is light and easy to handle with a weight of just 7.5 kg.

Versatile application options
  • The diamond core drill has a 3-speed gearbox with oil bath lubrication and offers idle speeds of 650, 1300 and 2600 rpm.
  • The machine's drill spindle has a 1¼" UNC external thread and a G½" internal thread for holding a core bit and a centre point.
  • The diamond core drilling machine is mounted on a core drill rig on the clamping neck (Ø 60 mm) of the machine. The diamond core drill is compatible with our KBS-252/Light-K, KBS-252/M-PRO, KBS-280M and TBS-3000/PRO core drill rigs.
  • The machine is connected to an industrial hoover or to the water supply via a GEKA® coupling and the supplied adapter for hoover (Ø 35 mm) or water supply (Gardena).
  • This enables optimum adaptation to a wide range of tasks.
Safety and robustness
  • Protective devices: Overcurrent, overvoltage and overheating protection and a carbon brush warning system as well as a slip clutch ensure operator safety and a long service life for the appliance.
  • Intelligent warning system: LED displays inform the operator about the current operating status and make it easier to monitor the device.
  • Coredrill stand: We always recommend the use of a core drill stand for safe and precise operation of the core drill. During hand-guided drilling, the core bit may jam and the machine may twist despite the protective mechanisms. A core drill stand provides stable guidance, reliably prevents the machine from twisting and enables precise drilling. This makes handling easier and noticeably increases work safety.
  • Sturdy storage case: The plastic case included in the scope of delivery is used for practical and careful storage of the machine and accessories supplied.

Optional accessories for DKB-202/H-PRO
In order to use the diamond core drilling machine safely and efficiently, we offer a range of optional accessories that have been specially developed to meet the requirements of professional craftsmen:

Core drill stands:
Core drill stand KBS-252/Light-K (item no. 6195)
Core drill rig KBS-252/M-PRO (item no. 6217)
Core drill rig KBS-280M (item no. 1909).
Telescopic core drill rig TBS-3000/PRO (item no. 6297).

The core drill stands are the perfect complement to the DKB-202/H-PRO core drill and are specially designed for precise and stable drilling work. The core drill stands are easy to transport and yet offer high stability and precision during drilling work.

Water tank WT-60 (item no. 6270) and WT-60/S (with hose reel | item no. 6271):
The WT-60 water tank or the WT-60/S variant with hose reel offer a reliable and flexible water supply for professional use on construction sites and in workshops.

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

Industrial hoover TS-38/HEPA (item no. 6442):
The TS-38/HEPA dry vacuum cleaner is a powerful and versatile cleaning device that is suitable for picking up dry, non-flammable dust.

Experience the impressive technology of the DKB-202/H-PRO diamond core drill and optimise your core drilling work for maximum precision and efficiency.

Advantages of wet core drilling
Wet core drilling offers several significant advantages over dry core drilling:
  • Reduced dust generation: wet core drilling uses water to cool the drilling area and bind the resulting dust. This results in a healthier working environment and less cleaning effort.
  • Effective cooling: The cooling effect of the water prevents the drill bit from overheating, which increases its service life. The constant cooling enables faster and more efficient drilling, as no breaks are required for cooling. Cooling also reduces the risk of material damage caused by overheating in the material around the hole.
  • Higher drilling quality: Wet drilling produces more precise and smoother holes, which are required for applications with high accuracy requirements.
  • Longer bit life: Water cooling results in less abrasion and longer tool life, which saves costs.
  • Reduced noise: The wet process is generally quieter than the dry process. The water dampens the vibrations and reduces the noise generated during the drilling process.
  • Faster drilling progress: Due to the lower friction and constant cooling, drilling can be carried out at a higher feed pressure and higher speed with the wet method. This means that wet drilling can generally be completed faster than dry 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 solid materials more effective.
  • Versatility in application: The wet method can be used for both vertical and horizontal drilling and is suitable for various materials (concrete, stone, brick).
The wet method for core drilling offers numerous advantages, particularly in terms of work safety, tool life and drilling quality. It is particularly recommended for demanding and precise drilling in hard materials and in dust-sensitive environments.

Advantages of dry core drilling

The dry method of producing a core hole also has some specific advantages over the wet method. Although it is used less frequently in certain situations, it has important advantages in suitable areas of application:
  • No water requirement: producing a core hole using the dry process is independent of the availability of a water connection. This also results in simpler logistics, as there is no need for hoses and fittings or a water supply system.
  • Prevention of water damage: With dry drilling, there is no risk of water damage, which is particularly important in sensitive buildings (e.g. old buildings) or in the vicinity of electrical installations.
  • Clean environment without water residue : With dry drilling, the surrounding area remains free of water and mud, which reduces the effort required to clean the work site afterwards.
  • Quick deployment and fewer accessories: As dry drilling does not require a water supply system, the equipment is generally easier and quicker to set up.
  • Lower costs: Dry drilling is generally less expensive than wet drilling, as no water supply system and fewer accessories are required. Cleaning costs are also largely eliminated as no sludge is produced.
  • Flexibility and mobility: Dry drilling is often more flexible and easier to mobilise as less equipment is required. The dry method is well suited to smaller boreholes, where the disadvantages such as dust generation are less significant.
  • No sludge or waste water: While wet drilling often produces sludge that has to be disposed of, dry drilling is more environmentally friendly in this respect.
  • Reduced risk at low temperatures: Dry drilling offers advantages in cold environments or at low temperatures, as water can freeze and thus hinder work. Especially in winter conditions, dry drilling offers a safe alternative to the wet method.
Dry core drilling has clear advantages in situations where water is undesirable or difficult to handle, such as indoors, in remote locations or when working in sensitive environments. It is particularly suitable for smaller holes and offers a practical, cost-effective and flexible solution for a wide range of applications.
