Drill Bit GRAPHITE SDS+ 6 mm for Concrete, model 57H406

GRAPHITE SDS+ 6 mm drill bit for concrete (model 57H406) is a rotary hammer accessory intended for drilling small-diameter holes in concrete, brick and masonry. The bit features an SDS+ shank for quick, tool-free insertion and removal in compatible rotary hammers. With a 6 mm cutting diameter it is suitable for drilling anchor holes, dowel installation and cable or conduit passages where compact, precise holes are required.

Advantages

The SDS+ connection ensures stable and accurate bit retention during percussive drilling, reducing slippage and wear at the tool-holder interface. The 6 mm diameter provides controlled, precise holes for anchors and fixings while minimising material damage. This drill bit is designed for use with rotary hammers, offering efficient impact energy transfer to the carbide tip for faster penetration into concrete and masonry. The construction balances durability and affordability for both professional and DIY tasks.

Suitable for

• Drilling 6 mm anchor and dowel holes in concrete and brick
• Creating small cable or conduit entries through masonry
• Light to medium-duty fastening and installation tasks

Key specifications

• Shank type: SDS+
• Cutting diameter: 6 mm
• Primary material compatibility: concrete, brick, masonry
• Tip type: carbide-tipped for improved wear resistance
• Intended tool: rotary hammer with SDS+ chuck

How to use

Insert the SDS+ shank into the rotary hammer’s chuck until it locks, ensuring the tool is disconnected from power during bit changes. Mark the drilling point and, where possible, start at low speed to position the bit accurately. Apply steady pressure, allowing the hammer action to provide most of the drilling force. Periodically withdraw the bit to clear dust and reduce heat build-up. After finishing, remove the bit by pulling it out of the chuck with the tool powered off.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and gloves. Match drilling speed and pressure to the material to avoid bit breakage: moderate pressure and full hammer action for concrete; reduce force on brittle masonry. For repetitive or deep holes, clear debris frequently and allow the bit to cool. Verify compatibility with your rotary hammer’s SDS+ system before use.
