## Summary description

GRAPHITE SDS+ drill bit 16 mm (57H478) designed for drilling into concrete and masonry using SDS+ rotary hammer drills. The 16 mm diameter bit fits SDS+ chucks and is intended for creating clean through-holes in construction and renovation tasks. Suitable for applications such as installing anchors, conduits, and fasteners where concrete drilling is required.

## Long description

The GRAPHITE SDS+ drill bit 16 mm (model 57H478) is designed for drilling through concrete and masonry with rotary hammer drills that accept SDS+ shanks. The 16 mm diameter and carbide tip geometry provide stable, precise penetration for creating clean through-holes in reinforced and non-reinforced concrete, brick and similar materials. The bit's shank fits SDS+ chucks for secure engagement and efficient impact transfer during hammer-drilling operations.
Advantages
This drill bit offers accurate hole sizing with a durable carbide tip that maintains cutting performance under repeated use. The SDS+ shank ensures reliable retention in compatible rotary hammers and reduces slippage during heavy-duty drilling. The design promotes chip evacuation and helps produce smooth, round holes suitable for anchors, sleeves and pipe passages. The 16 mm diameter is a common size for many fastening and installation tasks.
Suitable for
 Drilling through reinforced and non-reinforced concrete
 Creating holes for anchor bolts and chemical anchors
 Installing electrical conduits and plumbing sleeves
 General masonry drilling in brick, block and stone
Key specifications
 Type: SDS+ rotary hammer drill bit
 Diameter: 16 mm
 Tip: carbide cutting tip for concrete and masonry
 Shank: SDS+ compatible shank for secure engagement
 Intended use: through-holes in concrete and masonry
How to use
Install the bit into an SDS+ rotary hammer chuck until it locks in place. Select the rotary hammer's hammer-drill mode and choose an appropriate speed and impact setting for 16 mm diameter drilling in concrete. Start drilling with light axial pressure to establish the hole, then apply steady pressure while allowing the tool's impact action to do the work. Periodically withdraw the bit to clear dust and debris and to prevent overheating. For deep holes, drill in stages and clear the hole between passes.
Usage recommendations
Use appropriate personal protective equipment such as eye protection, hearing protection and gloves. Match the drill's power and impact energy to the bit size and the hardness of the material. For installing anchors, verify hole depth and cleanliness before inserting fasteners. Replace the bit when carbide wear reduces drilling efficiency or hole quality.
