Diamond core drill bit Silver SDS-Plus for concrete 120 mm (model 0559)

Diamond core drill bit Silver SDS-Plus for concrete 120 mm is a specialist cutting tool designed to create large-diameter holes in reinforced and plain concrete, masonry and similar hard materials. Equipped with an SDS-Plus shank, this core bit fits SDS-Plus hammer drills and rotary hammers to deliver efficient material removal when installing pipes, conduits, anchors or performing construction and renovation tasks.

Advantages

The diamond-segmented rim provides fast penetration and controlled cutting in dense substrates while maintaining a long service life compared with standard carbide bits. The SDS-Plus shank ensures secure retention in compatible power tools and quick bit changes on the job. Its 120 mm cutting diameter offers a balance between hole size and manageable drilling time for common utility and structural openings.

Suitable for

• Drilling circular openings for pipes and conduits in concrete walls and floors
• Creating passages for electrical and plumbing installations
• Making anchor or sleeve holes in reinforced concrete
• Renovation and construction tasks requiring clean, large-diameter holes in masonry

Key specifications

• Cutting diameter: 120 mm
• Shank type: SDS-Plus
• Cutting edge: diamond-segmented rim for hard materials
• Intended materials: reinforced concrete, plain concrete, masonry
• Typical tool compatibility: SDS-Plus hammer drills and rotary hammers

How to use

Install the core drill bit into an SDS-Plus chuck according to the power tool manufacturer’s instructions, ensuring the bit locks securely. Mark and, if needed, pilot the drilling location. For best results, operate the hammer drill at the recommended speed and apply steady axial pressure without excessive force. Use water cooling or periodic withdrawal to remove debris and reduce heat when drilling through dense concrete; follow the tool and bit manufacturer guidance regarding wet or dry drilling. After reaching the required depth, withdraw the core bit while the tool is running briefly to clear the cut surface, then stop the tool before removing the bit.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection, gloves and a dust mask or respirator. When drilling reinforced concrete, proceed with caution to avoid sudden tool binding if the bit contacts metal reinforcement; consider using lower speed and intermittent drilling. Match the drill’s power and speed range to the diameter of the core bit to maintain stable operation and prolong bit life.
