SID352/PRO soft-hammer core drill for wet and dry operation

The newly developed SID352/PRO soft-hammer core drill, with its soft-hammer drilling mode for dry drilling, enables core drilling in reinforced concrete up to a diameter of 352 mm. Naturally, it also has everything required for use in conventional and wet drilling applications. Using the soft-hammer core drill in conjunction with our vibration-damping core drilling stand IDS352/V-PRO ensures safe and precise results, whether using wet or dry drilling methods.

Powerful and effortless to use
The 3,300-watt electric motor delivers very high torque and is suitable for all tasks up to a maximum drilling diameter of 352 mm. Despite its power, the SID352/PRO soft-hammer core drill, weighing just 18 kg, is light and easy to handle.

The SID352/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 SID352/PRO soft-hammer core drill features a 3-speed gearbox with oil-bath lubrication and offers idle speeds of 512, 1062 and 1576 rpm.
• The core drill can be operated either with the soft-hammer function at impact rates of 12,288, 25,488 and 37,824 1/min or in normal drilling mode. The soft hammer function is activated easily via the mode selector ring on the drill spindle.
• The machine’s drill spindle features a 1¼"-UNC external thread and a G½" internal thread for mounting a core bit and a centring tip.
• A mounting adapter is used to secure the SID352/PRO soft-hammer core drilling unit to the core drilling stand. The machine is compatible with our core drilling stands IDS352/V-PRO, KBS352/PRO, KBS352/XL-PRO and KBS-502/M-PRO.
• Connection to an industrial vacuum cleaner or the water supply is made on the machine side via a GEKA® coupling and the supplied adaptors for vacuum cleaners (Ø 35 mm) or the water supply (Gardena).
• This allows for optimal adaptation to a wide variety of tasks.

Safety and robustness

• Safety features:Overcurrent, overvoltage and overheating protection, as well as 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 tool.

Advantages of dry core drilling
The dry method of core drilling also offers a number of specific advantages over the wet method. Although it is used less frequently in certain situations, it provides significant benefits in suitable applications:

• No water required: Dry coredrilling is not dependent on the availability of a water supply. This also simplifies logistics, as there is no need for hoses, 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 the case of sensitive buildings (e.g. older buildings) or near electrical installations.
• Clean environment with no water residue: With dry drilling, the surrounding area remains free of water and mud, which reduces the effort required for the final clean-up of the work site.
• Quick set-up and fewer accessories: As dry drilling does not require a water supply system, the equipment is generally simpler and quicker to set up.
• Lower costs: Dry drilling is generally more cost-effective than wet drilling, as no water supply system is required and fewer accessories are needed. Cleaning costs are also largely eliminated, as no slurry is produced.
• Flexibility and mobility: Dry drilling is often more flexible and easier to use on the move, as less equipment is required. The dry method is well suited to smaller boreholes, where drawbacks such as dust generation are less of a concern.
• No slurry or waste water: Whilst wet drilling often produces slurry that needs to be disposed of, dry drilling is more environmentally friendly in this respect.
• Lower risk at low temperatures: Dry drilling offers advantages in cold environments or at low temperatures, as water can freeze and thus hinder the work. Particularly in wintry conditions, dry drilling provides a safe alternative to the wet method.

Dry core drilling has clear advantages in situations where water is undesirable or difficult to manage, such as indoors, in remote locations or when working in sensitive environments. It is particularly well suited to smaller boreholes and offers a practical, cost-effective and flexible solution for a wide range of applications.

Advantages of wet core drilling
Wet core drilling offers several key advantages over dry core drilling:

• Reduced dust generation: Wet coredrilling uses water to cool the drilling area and bind the dust produced. This results in a healthier working environment and less cleaning work.
• 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 holes, 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 pressure and speed. 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 solid 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.
