Drill Bit GRAPHITE SDS+ 18 mm for Concrete, model 57H484

GRAPHITE SDS+ 18 mm drill bit for concrete (model 57H484) is a rotary hammer accessory designed for SDS+ chuck systems. With an 18 mm diameter it is intended for drilling precise holes in concrete and masonry. The bit features an SDS+ shank for quick, tool-free insertion and secure retention in compatible rotary hammers, making it suitable for installation of anchors, dowels and through-holes in construction, renovation and general fixing tasks.

Advantages

The GRAPHITE SDS+ 18 mm drill bit combines a carbide tip geometry with a robust steel body to provide reliable drilling performance in reinforced concrete and common masonry materials. The SDS+ shank ensures fast and stable coupling with rotary hammers, reducing play during impact drilling. The bit’s 18 mm diameter offers a balance between hole size and tool load for common anchor and dowel applications.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Making through-holes for pipes and cables in renovation work
• Preparatory drilling for fixing frames, rails and brackets
• General construction and repair tasks with SDS+ rotary hammers

Key specifications

• Diameter: 18 mm
• Shank type: SDS+
• Intended material: concrete and masonry
• Application: impact drilling with rotary hammers
• Length: suitable for standard anchor and through-hole depths (check tool and anchor requirements)

How to use

Fit the GRAPHITE SDS+ 18 mm drill bit into the SDS+ chuck of a compatible rotary hammer until it locks. Set the tool to hammer drilling mode and position the bit perpendicular to the work surface. Start drilling at low speed to create a centring point, then apply steady pressure while allowing the tool’s impact mechanism to do the work. Withdraw the bit periodically to clear dust and debris for efficient cutting and to prevent overheating. Select drill depth according to anchor or dowel length and follow the fixing manufacturer’s instructions for hole preparation and cleaning.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) when drilling concrete. Match drill length and diameter to anchor specifications and avoid excessive lateral force. For prolonged or heavy-duty drilling, allow cooling intervals and clear debris frequently to maintain bit life and drilling performance.
