Concrete drill bit GEKO G40007 125 mm, SDS Plus shank

Concrete drill bit GEKO G40007 125 mm with an SDS Plus shank is engineered for drilling clean, accurate holes in concrete, reinforced concrete and similar masonry materials. Designed for use with SDS Plus rotary hammers, the 125 mm working length lets you create holes for anchors, dowels and through-fixings commonly required in construction, renovation and installation tasks. The SDS Plus connection ensures secure bit retention and quick bit changes under impact drilling conditions.

Advantages

The drill bit delivers consistent drilling performance in masonry due to a carbide-tipped cutting head that sustains impact loads and maintains edge life. The 125 mm length provides a balance between reach and control for typical anchor and dowel installations. The SDS Plus shank offers fast, reliable coupling with compatible rotary hammers and reduces slippage during operation. Manufactured to standard dimensional tolerances, the bit is suitable for professional and DIY use where precise hole size and repeatable results are required.

Suitable for

• Drilling holes for concrete anchors and chemical anchors
• Installing dowels and fasteners in masonry
• Electrical, plumbing and HVAC mounting points in concrete walls and floors
• Repair and renovation work requiring clean, repeatable holes in reinforced concrete

Key specifications

• Overall length: 125 mm (working length appropriate for typical anchor installations)
• Shank type: SDS Plus for use with compatible rotary hammers
• Tip material: carbide-tipped cutting head for improved wear resistance
• Application material: concrete, reinforced concrete and masonry
• Drilling method: rotary hammer impact drilling

How to use

Fit the bit into the SDS Plus chuck of a compatible rotary hammer until it engages. Select an appropriate hammer mode—impact rotary mode for concrete—and set drill speed and impact energy according to the tool manufacturer’s guidance and the substrate hardness. Start drilling with light axial pressure to centre the bit, then apply steady pressure without forcing. Withdraw the bit periodically to clear dust and allow cooling when drilling deep holes. After drilling, clean the hole before inserting anchors or fasteners.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask when drilling concrete. Match drill diameter to the anchor or dowel size, and confirm compatibility between the SDS Plus rotary hammer and the bit shank. For reinforced concrete, use intermittent drilling and reduced feed pressure when encountering rebar to avoid damage to the carbide tip.
