Diamond core drill bit GEKO 182x10x450 mm 16T 1¼" for wet and dry drilling

Diamond core drill bit GEKO 182x10x450 mm 16T 1¼" for wet and dry drilling is a precision cutting tool designed for creating large-diameter holes in hard materials. The bit measures 182 mm in diameter, has a 10 mm segment height, and an overall length of 450 mm with a 1¼" connection that fits many core drilling machines. Its diamond-segment cutting edge with 16 teeth enables efficient material removal and accurate, clean cores when working with masonry, concrete, natural stone and similar substrates.

Advantages

The GEKO diamond core drill bit combines a robust segment matrix and consistent tooth layout to deliver reliable cutting performance in both wet and dry conditions. Its construction reduces vibration and improves centre stability, which helps achieve straight, true holes and better core quality. The 1¼" connection ensures secure mounting on compatible core drills, and the bit’s dimensions are chosen for common installation and sampling applications where precision and durability are required.

Suitable for

• Creating openings for plumbing and HVAC penetrations in concrete and masonry
• Cutting holes for electrical conduits and large-diameter installations
• Core sampling and material testing in construction and renovation projects
• Drilling through natural stone, reinforced concrete and blockwork

Key specifications

• Diameter: 182 mm
• Segment height: 10 mm
• Overall length: 450 mm
• Number of teeth/segments: 16
• Connection: 1¼" thread
• Suitable drilling modes: wet and dry
• Applicable materials: masonry, concrete, stone and similar hard substrates

How to use

Mount the diamond core bit securely to a compatible core drilling machine with a 1¼" connection, making sure the tool is correctly tightened and aligned. For wet drilling, provide continuous water supply to the bit during rotation to cool the diamond segments and remove slurry; for dry drilling, use intermittent pressure and allow the bit to cool periodically to avoid overheating. Start drilling at low speed to establish a pilot groove or use a guide to keep the bit centered, then increase speed and steady feed pressure appropriate to the machine and material. Withdraw periodically to clear debris and inspect the core and segment wear.

Usage recommendations

Use water cooling whenever possible for extended life and consistent cutting; when dry drilling, monitor temperature and take regular cooling breaks. Always wear appropriate personal protective equipment, secure the workpiece, and follow the core drill machine manufacturer’s safety instructions and operating limits.
