Diamond drill bits (wet)

Wet diamond drill bits work with water cooling and are the standard choice for professional core drilling in reinforced concrete. The water cools the diamond segments, flushes out drilling debris and extends bit life significantly. From installation firms to core drilling companies, wet drilling is the most widely used method for holes in hard construction elements.

Water cooling for maximum performance

The water flowing through the bit serves three functions simultaneously: cooling the diamond segments, evacuating drilling debris and lubricating the cutting face. This allows the bit to run at a constant speed without overheating, resulting in a longer service life and a cleaner bore edge. In thick reinforced concrete, water cooling is virtually indispensable because the steel rebar generates extreme heat.

Professional core drilling

Wet diamond drill bits are used for core drilling in concrete walls, floors and ceilings. Applications range from small pipe penetrations at 32 mm to large openings for ventilation ducts and sewer pipes up to 500 mm. For rig-mounted work you use a drill stand with a water connection; for smaller holes a handheld drill with water feed suffices. Before drilling into existing structures it is wise to scan for rebar and services with a concrete scanner to avoid surprises.

Longer life, lower consumption

Before core drilling into existing structures, scan the area with a rebar detector or concrete scanner. This avoids hitting reinforcement or buried services unexpectedly, protecting both the bit and the structure. A few minutes of scanning can save hours of rework.

Thanks to water cooling, wet diamond drill bits last significantly longer than dry variants, especially in reinforced concrete. The investment in a water supply pays back through fewer bit changes and higher drilling speed. Browse our wet diamond drill bit range and choose the right diameter for your project.
