Drill bit GRAPHITE SDS+ 16 mm for concrete, model 57H470

GRAPHITE SDS+ drill bit 16 mm (model 57H470) is engineered for drilling into concrete, masonry and reinforced concrete with SDS+ rotary hammer systems. Its 16 mm diameter is suitable for creating anchor holes, through-holes and dowel sockets where a straight, clean bore is required. The bit combines a carbide tip geometry with a robust flute design to remove dust efficiently and maintain drilling progress on demanding materials.

Advantages

The SDS+ shank ensures secure connection with compatible rotary hammers for reliable power transfer and reduced slippage. A carbide-tipped cutting head increases wear resistance and maintains cutting performance over repeated use. The flute profile facilitates efficient debris evacuation, which reduces friction and heat buildup during continuous drilling. Constructed for both professional and DIY tasks, the bit provides consistent hole accuracy and service life appropriate for standard anchoring and fixture installation.

Suitable for

• Drilling anchor and dowel holes in concrete
• Through-hole drilling in masonry and reinforced concrete
• Preparing holes for fixtures, rails and cable conduits
• Use with SDS+ rotary hammer drills for medium to heavy-duty applications

Key specifications

• Nominal diameter: 16 mm
• Compatible shank type: SDS+
• Intended material: concrete, masonry, reinforced concrete
• Tip: carbide-tipped cutting head for enhanced wear resistance
• Design: spiral flutes for efficient dust removal
• Typical use: anchor, dowel and through-hole drilling

How to use

Install the drill bit into an SDS+ rotary hammer following the tool manufacturer's instructions until it locks in place. Select hammer drilling mode when working in concrete or reinforced concrete. Start drilling at low speed to create a guide point, then apply steady pressure while allowing the hammer action to perform the cutting. Maintain a perpendicular angle to the work surface for a straight hole and periodically withdraw the bit to clear accumulated dust for deeper holes.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust mask. Avoid excessive lateral force on the bit to prevent breakage; for large-diameter or very deep holes consider step drilling or using specialized core tools. Store the bit dry and clean to prevent corrosion and inspect the carbide tip before use to ensure optimal performance.
