Drill Bit GRAPHITE SDS+ 14 mm for concrete, model 57H454

GRAPHITE SDS+ 14 mm drill bit for concrete (model 57H454) is a masonry drill bit designed for use with SDS+ rotary hammer drills. It is intended for drilling holes in concrete, reinforced concrete and other hard masonry materials. The 14 mm diameter provides a balance between hole size and drilling speed, making this bit suitable for mounting anchors, fixing bolts and through-holes in construction and renovation tasks.

Advantages

The SDS+ shank ensures quick, secure insertion into compatible rotary hammers and reliable torque transfer during hammer drilling. The carbide tip and optimized flute geometry help maintain cutting performance and chip evacuation when working in dense concrete. The bit’s 14 mm diameter offers consistent hole dimensions for commonly used anchors and fixings while maintaining acceptable drilling speed and tool load.

Suitable for

• Drilling anchor or dowel holes in concrete and reinforced concrete
• Creating through-holes for cables and pipes in masonry walls
• Fixing fixtures, brackets and frames to concrete surfaces
• Professional construction and DIY renovation projects requiring reliable masonry drilling

Key specifications

• Drill type: masonry drill bit with SDS+ shank
• Diameter: 14 mm
• Intended material: concrete and other hard masonry
• Tip material: carbide cutting tip for improved wear resistance
• Flute design: spiraled flute for chip removal and cooling
• Compatible tool type: SDS+ rotary hammer drills

How to use

Fit the SDS+ shank into the rotary hammer’s chuck until it locks. Set the tool to hammer-drill mode and select an appropriate rotational speed for the concrete hardness—use lower speed and steady pressure for heavily reinforced or very dense concrete. Begin drilling with light, consistent pressure; allow the hammer action to do the work and avoid excessive force that can blunt the tip or damage the drill. Periodically withdraw the bit to clear dust and improve cooling, especially when drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. When drilling through reinforced concrete, monitor for steel rebar contact and consider using a specialized rebar-cutting bit if frequent rebar hits occur. For longer service life, avoid overheating the bit by using intermittent drilling and clearing chips frequently.
