Drill Bit GEKO SDS MAX 18 mm, model G41860

GEKO SDS MAX 18 mm drill bit model G41860 is a purpose-built masonry and concrete drilling tool compatible with SDS MAX rotary hammers. With an 18 mm diameter and an SDS MAX shank, the bit is designed to deliver stable engagement with the hammer’s chuck and efficient material removal when used on concrete, brick, block and similar mineral substrates. It is intended for professional and DIY applications where precision and reliable penetration in hard materials are required.

Advantages

The SDS MAX design provides secure, vibration-minimising retention in compatible rotary hammers and reduces slippage during heavy-duty drilling. The 18 mm cutting diameter balances removal rate and hole accuracy for common anchoring and fixing tasks. The bit’s geometry and flute profile are optimised for efficient dust evacuation and reduced clogging when drilling into dense mineral materials.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Installing sleeves, dowels and chemical anchors in masonry
• Making passages for plumbing and electrical conduits through block and brickwork
• General construction and renovation tasks requiring repeatable holes in hard mineral substrates

Key specifications

• Diameter: 18 mm
• Shank type: SDS MAX
• Suitable materials: concrete, reinforced concrete, brick, block and similar masonry
• Intended use: rotary hammer drilling (impact/drill mode)

How to use

Secure the drill bit into an SDS MAX compatible rotary hammer following the tool manufacturer’s instructions. Mark the drilling location, position the bit perpendicular to the surface and start drilling at low speed to establish the hole, then apply steady pressure and allow the hammer action to advance through the material. Periodically withdraw the bit to clear debris and improve dust removal. Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask, and follow safe work practices when drilling into structural elements.

Usage recommendations

For best results when drilling deep or reinforced concrete, use a rotary hammer with adequate impact energy for an 18 mm SDS MAX bit and consider using dust extraction or a vacuum attachment to reduce airborne particles. Replace the bit if cutting edges become worn or if drilling performance degrades.
