Drill Bit GRAPHITE SDS+ 18 mm model 57H480, for hammer drills

GRAPHITE SDS+ 18 mm drill bit (model 57H480) is designed for use with hammer drills that accept SDS+ shanks. The bit features an 18 mm cutting diameter and a carbide-tipped head suitable for impact drilling into concrete, masonry and similar hard substrates. It provides a secure SDS+ connection for fast bit changes and stable drilling under hammer action, making it suitable for both professional tradesmen and DIY users who need reliable performance when creating holes for anchors, dowels and pipe penetrations.

Advantages

The drill bit combines a robust carbide tip with a fluted body optimized for efficient dust removal and reduced clogging during drilling. Its SDS+ shank ensures firm retention in compatible hammer drills and allows quick insertion and release. The 18 mm diameter gives a balance between hole size and drilling speed for common fixing and installation tasks in concrete and masonry. The design focuses on durability under repeated impact loads and consistent hole accuracy.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Installing wall plugs, anchors and fasteners in masonry
• Creating passage holes for pipes and conduits
• General-purpose impact drilling with SDS+ hammer drills

Key specifications

• Shank type: SDS+
• Cutting diameter: 18 mm
• Tip material: carbide-tipped cutting head
• Intended materials: concrete, masonry and similar hard substrates
• Application: rotary with impact / hammer drilling

How to use

Fit the SDS+ shank securely into the hammer drill chuck until it clicks into place. Select an appropriate drilling mode with percussion enabled and start drilling at low speed to establish a pilot position, then increase speed while maintaining steady pressure without forcing the bit. Periodically withdraw the bit to clear dust and debris from the hole and to allow the bit to cool. For deeper holes, withdraw more frequently to remove accumulated material and reduce wear on the carbide tip.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Match drill speed and feed pressure to the material; excessive overheating or side loading should be avoided to prolong bit life. For reinforced concrete, maintain a straight drilling line and clear rebar obstructions carefully. Store the drill bit in a protective case or holder to prevent damage to the carbide tip when not in use.
