Drill bit Smart SDS MAX 22 mm for concrete, model 18-220920

The Smart SDS MAX 22 mm drill bit for concrete, model 18-220920, is a rotary-hammer masonry bit engineered for drilling clean, accurate holes in reinforced and non-reinforced concrete, brick and similar mineral substrates. Designed to fit SDS MAX chucks, this 22 mm diameter bit provides consistent drilling performance and efficient chip evacuation for professional and DIY applications requiring reliable penetration and hole quality.

Advantages

This SDS MAX masonry bit delivers steady drilling progress and reduced clogging thanks to an optimized flute geometry that promotes fast dust and debris removal. The robust tip and reinforced body are built to withstand the impacts and torsional loads typical of rotary-hammer use. Compatibility with standard SDS MAX rotary hammers ensures secure seating in the tool and minimizes play during operation, helping to preserve hole accuracy over repeated use.

Suitable for

• Drilling anchor, dowel and through-holes in reinforced concrete
• Making service and installation holes in brick and block walls
• Preparing fixing points for mechanical and electrical installations
• Construction and renovation tasks requiring SDS MAX rotary hammers

Key specifications

• Shank type: SDS MAX-compatible shank for rotary-hammer tools
• Diameter: 22 mm
• Intended material: reinforced and non-reinforced concrete, brick, masonry
• Tip design: carbide or reinforced tip suitable for percussive drilling
• Flute design: spiral/optimized for chip removal and dust evacuation

How to use

Securely insert the SDS MAX shank into the rotary hammer’s chuck until it locks according to the tool manufacturer’s instructions. Select an appropriate drilling mode (rotary hammer with percussion) and set the correct speed and impact settings for 22 mm diameter drilling in concrete. Begin drilling with steady axial pressure—avoid excessive force that can overload the bit or tool. Periodically withdraw the bit to clear accumulated dust and debris for efficient cutting and to prevent overheating. When drilling through reinforced concrete, maintain controlled feed to allow the tip to cut rebar or to change to a rebar-cutting bit if required.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask) and follow manufacturer guidance for the rotary hammer. For prolonged drilling sessions, allow the bit and tool to cool periodically and inspect the tip for wear; replace the bit when cutting performance or hole quality declines.
