Diamond core drill bit GEKO 72x10x450 mm 7T 1¼" for wet and dry drilling

Diamond core drill bit GEKO 72x10x450 mm with a 7T diamond cutting edge and a 1¼" connection is designed for wet and dry core drilling in masonry, concrete, brick and similar materials. The 450 mm overall length provides extended reach for deeper holes or when working from scaffolding and through thicker structural elements. The diamond segments ensure efficient material removal and longer service life when paired with appropriate drilling rigs and correct operating conditions.

Advantages

The GEKO diamond core bit combines a long shaft with a durable 7T diamond crown that delivers stable cutting performance and resistance to wear. Compatibility with a 1¼" thread allows use with many standard core drilling machines, while suitability for both wet and dry drilling increases versatility on different job sites. The design focuses on straight, clean hole production and extended durability under normal operating conditions.

Suitable for

• Creating circular holes in reinforced and non-reinforced concrete
• Drilling openings in masonry and brickwork for plumbing and electrical installations
• Installing anchors, sleeves, and pipe penetrations
• Working on renovation sites where both wet and dry drilling are required

Key specifications

• Cutting diameter: 72 mm
• Segment height: 10 mm
• Overall length: 450 mm
• Diamond segment type: 7T diamond crown
• Connection/thread: 1¼" (standard core bit thread)
• Drilling method: Suitable for wet and dry core drilling

How to use

Secure the core bit to a compatible drilling machine using the 1¼" connection and ensure the machine is mounted or handheld according to the tool’s specifications. For dry drilling, use intermittent pressure and allow cooling pauses to avoid overheating the diamond segments; for wet drilling, provide a steady water supply to the cutting edge to flush out debris and cool the bit. Start drilling at low speed to establish a guide groove, then increase speed and apply even axial pressure. Remove the core periodically to clear cuttings and inspect the segments for wear.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, dust mask or respirator for dry drilling, hearing protection and gloves. Match drilling speed and feed rate to the material being drilled and the drilling machine’s specifications. For reinforced concrete or abrasive materials, consider using wet drilling or a drill rig with proper cooling to extend tool life.
