Drill bit GRAPHITE SDS+ 18 mm for concrete (57H482)

GRAPHITE SDS+ 18 mm drill bit for concrete is designed for percussion drilling in concrete, brick and masonry. The 18 mm diameter and SDS+ shank provide secure engagement with compatible rotary hammers, while the reinforced cutting tip maintains drilling performance when creating holes for anchors, fasteners or conduits. This drill bit is intended for both professional tradespeople and DIY users who require a reliable tool for routine fixing and installation tasks in solid building materials.

Advantages

The SDS+ shank ensures fast and secure bit changes and reduces slippage during heavy-duty drilling. The cutting tip is reinforced to withstand impact loads and preserve drilling precision over repeated use. The 18 mm diameter is suitable for common anchor sizes and conduit passages, offering a balance between hole clearance and material removal. The bit is compatible with most SDS+ rotary hammers, enabling percussive energy transfer for effective penetration of concrete and masonry.

Suitable for

• Drilling holes for concrete anchors and expansion bolts
• Installing electrical conduits and plumbing passages
• Fixing structural or non-structural fasteners in masonry
• Creating service penetrations for cables and pipes

Key specifications

• Diameter: 18 mm
• Shank type: SDS+
• Intended materials: concrete, brick, masonry
• Drilling method: percussion (rotary hammer compatible)

How to use

Select a rotary hammer that accepts SDS+ bits and set it to the hammer-drill mode. Mark the drilling position and, if necessary, use a center punch to prevent bit wandering. Insert the SDS+ shank into the tool until it locks. Start drilling at low speed to create a guide point, then increase power and maintain steady pressure without forcing the bit. Withdraw periodically to clear dust and prevent overheating. After reaching the required depth, switch off the tool and remove the bit by pulling the locking sleeve, then clean the hole before inserting anchors or fasteners.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For longer service life, avoid excessive side loads and overheating; allow the bit to cool and clear debris frequently during extended drilling. Match hole diameter to anchor specifications and follow manufacturer instructions for both the rotary hammer and installed fasteners.
