Diamond core drill bit 100 mm with SDS+ adapter Dedra DED1507-D

Diamond core drill bit 100 mm with SDS+ adapter Dedra DED1507-D is a 100 mm diameter diamond-tipped core bit designed for drilling circular holes in masonry, concrete, brick and other mineral materials. The diamond cutting edge ensures efficient cutting and longer tool life when used with rotary hammer drills that accept SDS+ shanks. The tool is intended for creating clean, precise openings for pipes, conduits, anchors and other installations during renovation and construction work.

Advantages

The diamond segment cutting edge provides effective material removal and resistance to wear, increasing drilling speed and reducing the need for frequent replacement. The SDS+ adapter enables quick, secure mounting in compatible rotary hammers and ensures reliable torque transfer. The 100 mm diameter is a common size for plumbing and electrical penetrations, offering a balance between drilled opening size and structural integrity of the workpiece.

Suitable for

• Drilling holes for plumbing pipes and fixtures in concrete and brick
• Creating openings for electrical conduits and junction boxes
• HVAC installations requiring precise circular penetrations
• Renovation and repair work in masonry and reinforced concrete

Key specifications

• Cutting diameter: 100 mm
• Cutting edge: diamond segment
• Shank type: SDS+ adapter
• Recommended material: masonry, concrete, brick and other mineral materials
• Typical use: core drilling for circular openings

How to use

Secure the SDS+ adapter into a compatible rotary hammer and verify the tool is locked in position. Mark the center of the hole and use a pilot bit or guide to stabilize the core bit at the start if necessary. Begin drilling at low speed to establish the cut, apply steady axial pressure and allow the diamond segments to cut without forcing the bit. Use water cooling where appropriate and possible to prolong segment life and reduce dust; if using water, ensure the power tool and work area are protected from moisture. Withdraw the core bit occasionally to remove debris and clear the hole for continuous efficient cutting.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask or extraction. Match the rotary hammer settings to the manufacturer’s guidance for coring bits and avoid excessive lateral force. For reinforced concrete, proceed with caution and monitor bit wear; replace the bit when cutting performance decreases markedly.
