Drill bit GRAPHITE SDS+ for concrete 14 mm (57H456)

GRAPHITE SDS+ drill bit for concrete, 14 mm diameter, is designed for use with SDS+ rotary hammer drills to create precise holes in concrete, masonry and natural stone. The bit features a robust design intended to deliver stable drilling performance for anchor installation, dowel fixing and other fastening tasks. Compatible with standard SDS+ chucks, this 14 mm concrete drill bit is suitable for both professional and DIY use when reliable hole quality and tool-fit are required.

Advantages

The SDS+ shank ensures fast and secure mounting in rotary hammer chucks and reduces slippage during heavy-duty percussion drilling. The optimized head geometry improves penetration into concrete and masonry while maintaining hole roundness. Solid construction and hardened working surfaces increase wear resistance and extend service life under normal drilling conditions. The 14 mm diameter provides a balance between material removal rate and control, making it effective for common anchor and dowel sizes.

Suitable for

• Drilling holes in concrete for anchors and mechanical fasteners
• Installing dowels, sleeves and fixing elements in masonry
• Preparing holes in stone and other hard mineral materials
• Professional construction work and home renovation projects

Key specifications

• Shank type: SDS+
• Tip diameter: 14 mm
• Intended materials: concrete, masonry, natural stone
• Typical application: rotary hammer percussion drilling
• Construction: hardened working tip and solid fluted body for chip removal

How to use

Mount the drill bit securely in an SDS+ rotary hammer chuck according to the drill manufacturer's instructions. Choose an appropriate drilling mode (hammer drilling) and set the drill to the recommended speed and percussion setting for concrete. Start drilling at moderate pressure, allowing the hammer action to do the work; avoid excessive axial force that may damage the bit or the drill. Withdraw the bit periodically to clear debris and prevent clogging. Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling concrete or masonry.

Usage recommendations

For best results, pre-mark and, if possible, center-punch the drilling point. When drilling deep holes, withdraw frequently to clear dust and reduce heat. Replace the bit when wear reduces cutting efficiency or when the tip is damaged to maintain hole accuracy and prevent chipping of the work surface.
