## Summary description

Diamond core drill bit GEKO, size 42x10x450 mm with 3T teeth and 1.1/4" connection, designed for dry and wet drilling. Suitable for cutting circular holes in concrete, masonry, brick and similar hard materials. Long shaft length allows deeper penetration; diamond segments provide efficient cutting and extended life in both wet-core and dry-core applications.

## Long description

Diamond core drill bit GEKO 42x10x450 mm 3T 1.1/4" for dry and wet drilling is a cylindrical cutting tool intended for making accurate circular holes in hard materials such as concrete, masonry and brick. The tool combines a long shaft for deeper penetration with diamond cutting segments that provide effective material removal in both wet and dry working conditions. The 1.1/4" connection ensures compatibility with common core drilling machines and rotary tools that accept this thread size.
Advantages
The diamond segments offer high abrasion resistance and steady cutting performance, extending the service life of the bit compared with conventional carbide cutters. The long 450 mm overall length enables drilling deeper holes without changing extensions, and the 3T tooth arrangement helps maintain stable cutting and faster core extraction. The bit is suitable for both wet and dry use, allowing flexibility for different jobsite conditions and reducing downtime for tool changes.
Suitable for
 Drilling clean circular holes in reinforced concrete and plain concrete
 Creating openings in brickwork and masonry for plumbing, electrical and HVAC installations
 Core sampling and conduit or pipe passage preparation
 Indoor and outdoor drilling where wet or dry methods are required
Key specifications
 Cutting diameter: 42 mm
 Cutting depth / segment length: 10 mm
 Overall length / shaft length: 450 mm
 Tooth arrangement: 3T (three segments)
 Connection thread type: 1.1/4" compatible thread for core drill machines
 Suitable drilling methods: dry drilling and wet drilling
 Typical target materials: concrete, masonry, brick
How to use
Mount the diamond core drill bit securely to a compatible core drilling machine or rotary tool using the 1.1/4" connection. Align the bit with the intended center point of the hole and start drilling at low speed to establish a guide groove. Increase speed and feed gradually while keeping the tool steady; use consistent pressure without forcing the bit. For wet drilling, supply a controlled water flow to cool the segments and remove slurry. For dry drilling, follow the manufacturer’s recommendations for intermittent drilling and cooling pauses to avoid overheating.
Usage recommendations
Use appropriate personal protective equipment such as eye protection, dust mask or respirator, hearing protection and gloves. When drilling reinforced concrete, take care to avoid striking rebar; if rebar is encountered, reduce feed pressure and use pulsed drilling. Select wet drilling when maximum segment life and dust suppression are priorities; choose dry drilling only where water cannot be used and apply intermittent operation to manage heat.
