Drill bit GRAPHITE SDS+ 16 mm for concrete, model 57H476

GRAPHITE SDS+ 16 mm drill bit model 57H476 is designed for drilling clean, precise holes in concrete and masonry. The bit is intended for use with SDS+ rotary hammer systems and is suitable for creating holes for anchors, dowels and through-fixings in both solid and reinforced concrete. Its 16 mm diameter provides a standard bore size commonly required for medium-duty fastening and installation tasks in construction and renovation.

Advantages

The SDS+ shank ensures quick, secure engagement with compatible rotary hammers and reduces slippage during high-impact drilling. The carbide-tipped cutting head maintains edge retention and wear resistance when drilling abrasive materials such as concrete and masonry. The rigid flute geometry facilitates efficient removal of dust and debris from the hole, improving drilling speed and reducing heat build-up.

Suitable for

• Drilling holes for anchor bolts and chemical anchors in concrete
• Installing dowels and through-fixings in masonry and stone
• Medium-duty construction and renovation work requiring 16 mm bore
• Professional and DIY tasks using SDS+ rotary hammer drills

Key specifications

• Drill type: SDS+ concrete drill bit
• Diameter: 16 mm
• Material tip: carbide-tipped cutting head for wear resistance
• Shank: SDS+ compatible shank for rotary hammer systems
• Intended materials: concrete, reinforced concrete, masonry, stone

How to use

Install the GRAPHITE SDS+ 16 mm drill bit into an SDS+ rotary hammer according to the tool manufacturer's instructions. Mark the drilling point and set the drill to hammer or rotary-hammer mode as required for concrete. Apply steady pressure and allow the tool to do the work; avoid excessive lateral force that can damage the bit or the work surface. Withdraw the bit periodically to clear dust and check progress. After drilling, clean the hole to ensure proper seating of anchors or dowels.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and a dust mask or extraction when drilling concrete. For deeper or larger-diameter holes, use progressive drilling with the correct drill length and allow the bit to cool periodically. Replace the bit when cutting performance declines or if the tip shows visible damage to maintain drilling quality and safety.
