Diamond core drill bit Diam S3 152 mm x 450 mm, 1 1/4" connection

The Diam S3 diamond core drill bit with a 152 mm cutting diameter and 450 mm overall length is designed for precise core drilling in concrete, masonry and reinforced concrete. With a 1 1/4" connection it is compatible with common core drilling rigs and rotary drills that accept this thread size. The segmented diamond crown and robust steel body provide effective cutting and chip removal when used in wet drilling mode, helping to maintain cutting performance and prolong tool life.

Advantages

The segmented diamond rim delivers fast penetration and controlled cutting in abrasive materials while reducing heat build-up during wet operation. The 450 mm overall length allows for deep core extraction and installation of openings for plumbing, electrical and HVAC services. The standard 1 1/4" connection ensures broad compatibility with professional drilling equipment, and the solid steel construction improves resistance to bending and torque stresses.

Suitable for

• Drilling cores in concrete and reinforced concrete
• Creating openings for plumbing pipes and conduit
• Installing HVAC ducts and cable passages
• Wet core drilling on masonry and brick

Key specifications

• Cutting diameter: 152 mm
• Overall length: 450 mm
• Connection type: 1 1/4" threaded connection
• Intended drilling mode: wet drilling
• Material compatibility: concrete, reinforced concrete, masonry, brick
• Construction: segmented diamond crown with steel body

How to use

Attach the core bit securely to a compatible drill or core rig with a 1 1/4" thread, ensure the mounting is tightened according to the drill manufacturer’s instructions, and set up a stable drilling rig or guide. Use continuous water flow for cooling and flushing slurry when performing wet drilling. Start at low speed to establish the pilot groove, then apply steady feed pressure and appropriate rotational speed for the material. Periodically withdraw the bit to remove debris and check progress until the required core depth is reached, then extract the core using the rig’s core extraction function.

Usage recommendations

Use with adequate water supply for cooling and dust suppression; do not operate the bit dry. Select an appropriate drill rig with torque capacity matching the bit diameter and material hardness. Inspect threads and body before use and replace the bit when diamond segments are worn to avoid reduced performance and potential damage.
