High-Performance Diamond Core Bits for Wet, Dry & Soft-Impact Drilling

High-Performance Diamond Core Bits for Wet, Dry & Soft-Impact Drilling

In the professional construction industry, the right tool and drilling technique determine efficiency and service life. In our range you will find heavy-duty diamond core bits for all common core drilling motors and building materials – from heavily reinforced concrete to hard clinker brick and abrasive sand-lime brick.

Our drilling categories at a glance

• Wet diamond core bits: The standard for extremely hard materials such as reinforced concrete and natural stone. The cooling water reliably flushes the drilling dust out of the hole, cools the segments and ensures maximum service life for stand-guided work.
• Dry diamond core bits: The perfect solution for renovation of old buildings, interior fit-out and places where no water may be used. Ideal for masonry, brick and soft building materials.
• Soft-impact core bits with spiral / helix: Developed especially for modern core drilling motors with switchable soft impact (e.g. WEKA DKS series). The integrated outer spiral conveys the solid drilling dust backwards at lightning speed when drilling dry in concrete. This prevents the bit from jamming, protects the diamond segments and ensures extremely fast drilling progress.

Technical features & quality standards

When choosing the right core bit, pay attention to the following specifications:

• Effective dust removal: Core bits with a helical / spiral groove, combined with dust extraction, guarantee clog-free work – even in hard concrete without water.
• Standardised connections: Available with standard connections such as 1 1/4" UNC for classic core drilling rigs or M16 / 1/2" for hand-held soft-impact machines.
• Laser-welded segments: Maximum protection against segment breakage – especially important under the load of micro-impact / soft-impact.

Expert tip for soft-impact dry drilling

When dry drilling in concrete with soft impact, always use a powerful dust extractor (class M). The constant airflow cools the laser-welded segments and, together with the helical spiral, enables the full removal performance of the diamonds.
