## Long description

GRAPHITE SDS+ drill bit 8 mm (model 57H420) is designed for drilling into concrete and masonry with rotary hammer drills featuring an SDS+ chuck. The 8 mm diameter delivers a practical compromise between drilling speed and hole size, making it suitable for common fastening tasks such as installing wall plugs, anchors and through-holes for services and fixtures. The SDS+ shank ensures consistent engagement with compatible hammer drills for reliable transfer of impact energy.
Advantages
The drill bit is engineered for use in concrete and similar materials, offering a hardened tip and flute geometry that evacuates dust efficiently to maintain drilling progress. Its SDS+ shank provides secure retention in the tool chuck and quick bit changes without additional accessories. The 8 mm working diameter allows for precise pilot holes and standard anchor fittings while keeping drilling time and effort moderate.
Suitable for
Drilling holes in concrete and masonry for wall plugs and anchors
Creating through-holes for pipes, conduits and fastening elements
Installation and renovation tasks requiring repeatable, consistent hole sizes
Professional and DIY applications with SDS+ rotary hammer drills
Key specifications
Shank type: SDS+
Working diameter: 8 mm
Intended material: concrete and masonry
Typical applications: fastening, installation, renovation
How to use
Fit the SDS+ shank securely into the compatible rotary hammer drill chuck and select the hammer drilling mode if available. Mark the drilling point and start at low speed to establish the position, then apply steady pressure while operating at appropriate speed and hammer action for the material. Withdraw the bit periodically to clear dust from the hole and prevent overheating. Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask.
Usage recommendations
For best results, use the drill bit with a rotary hammer that supports SDS+ bits and choose drill mode settings suited to concrete. Match the hole diameter to the anchor or plug specification and ensure steady, moderate pressure during drilling. Replace the bit when cutting performance declines or when the tip shows visible wear.
