Drill Bit GRAPHITE SDS+ 8 mm for concrete, model 57H416

GRAPHITE SDS+ drill bit 8 mm (model 57H416) is a straight-shank masonry drill designed for efficient drilling in concrete. Made for use with SDS+ rotary hammer chucks, the bit produces a single 8 mm diameter hole suitable for anchors, dowels and pass-through fixings. The design emphasizes durability and consistent hole size for professional and DIY concrete installation tasks.

Advantages

The drill bit features a hardened tip and spiral fluting that evacuates dust effectively, improving drilling speed and reducing bit clogging. Compatibility with SDS+ chucks ensures quick, secure mounting and stable operation in rotary hammer tools. The uniform 8 mm diameter provides predictable fitting for standard concrete anchors and fixings, while the robust construction increases resistance to wear during repeated use.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Creating pass-through holes for cables or pipes in masonry
• Professional construction and renovation work
• Home improvement and DIY fixing tasks

Key specifications

• Drill type: SDS+ masonry bit
• Material compatibility: concrete and general masonry
• Shank type: SDS+ straight shank for rotary hammers
• Drill diameter: 8 mm
• Tip design: hardened/ground tip for concrete drilling
• Flute type: spiral flutes for efficient dust removal

How to use

Insert the SDS+ shank firmly into the rotary hammer chuck until it locks. Select the hammer drilling mode on the tool if available, and position the bit perpendicularly to the concrete surface. Start drilling at low speed to establish the position, then apply steady pressure and allow the tool's hammer action to advance the bit. Withdraw periodically to clear dust from the hole if drilling deep openings. For through-holes, maintain alignment and monitor bit heating; pause if the bit becomes very hot.

Usage recommendations

Use appropriate personal protective equipment including eye protection and a dust mask. Match drill diameter to the anchor or dowel specifications and use a vacuum attachment or intermittent withdrawal to manage dust. For extended life, avoid excessive axial force beyond what the tool provides and keep the bit clean of debris between uses.
