SDS-Plus concrete drill bit GEKO Korona 100 mm G40005

The SDS-Plus concrete drill bit GEKO Korona 100 mm G40005 is designed for drilling holes in concrete, masonry and other hard mineral materials. It fits SDS-Plus rotary hammer chucks and provides a 100 mm drilling depth/length, enabling accurate hole preparation for anchors, dowels and through-holes during construction and renovation work. The bit’s shank and flute geometry are matched to impact drilling so it transfers force efficiently from the tool to the cutting tip.

Advantages

The drill bit offers consistent drilling performance in reinforced and non-reinforced concrete thanks to its optimized tip geometry and robust body. Its SDS-Plus shank ensures quick, secure mounting and reliable power transmission with reduced slippage. The 100 mm length provides sufficient depth for common fastening and fixture tasks without requiring excessive extension, while the flute design facilitates dust evacuation to maintain drilling speed and reduce heat build-up.

Suitable for

• Drilling holes in concrete and masonry for anchors and dowels
• Making through-holes for pipes and cable entries in building structures
• Preparation of fixing points for facade and interior installation work
• Renovation tasks requiring impact drilling with rotary hammers

Key specifications

• Shank type: SDS-Plus compatible
• Material compatibility: concrete, masonry and similar mineral substrates
• Overall drilling length/depth: 100 mm
• Flute: spiral design for dust removal during drilling
• Construction: impact-rated body optimized for rotary hammer use

How to use

Select an SDS-Plus rotary hammer with appropriate power and insert the bit into the chuck until it locks. Mark the drilling position, start at low speed to create a guide point, then apply steady axial pressure and allow the hammer action to perform the work. Periodically withdraw the bit to clear dust from the hole and reduce heat; for deep or long drilling runs, pause to let the bit cool. When drilling through reinforced sections, proceed with controlled pressure and slow advancement to avoid abrupt contact with rebar.

Usage recommendations

Use appropriate personal protective equipment (eye protection, hearing protection and dust mask) and clamp or support workpieces when possible. Match the drill bit length to the anchor or fixture depth required; for best results in dense concrete, use a hammer with adequate impact energy and avoid excessive lateral forces that can damage the bit or tool.
