Drill Bit Set GRAPHITE SDS+ for Concrete 8 mm, 10 pcs (57H578)

Set of GRAPHITE SDS+ drill bits with ten 8 mm diameter bits intended for drilling concrete and masonry. These bits are made for SDS+ chucks and are suitable for use with rotary hammers. The set is designed for repetitive drilling of anchor holes, dowels and general concrete fixing tasks in construction and renovation projects.

Advantages

The SDS+ design enables quick, secure bit mounting and efficient power transfer from the rotary hammer to the cutting head. Uniform 8 mm diameter across all ten pieces simplifies job planning and reduces the need to change tools during repetitive anchoring work. The bits are optimized for concrete and masonry materials, providing consistent hole quality and stable drilling performance over multiple cycles.

Suitable for

• Drilling anchor holes for dowels and fixings in concrete
• Preparing holes for mechanical anchors in masonry and blockwork
• Renovation and installation tasks requiring multiple identical holes
• Work with SDS+ rotary hammers on construction sites and in workshops

Key specifications

• Tip diameter: 8 mm
• Shank type: SDS+ compatible shank
• Quantity: 10 pieces per set
• Intended material: concrete and masonry
• Application: rotary hammer drilling for anchors and fixings

How to use

Fit an 8 mm SDS+ bit into the rotary hammer’s chuck until it locks. Set the drill to hammer mode and position the bit perpendicular to the work surface. Apply steady pressure and allow the hammer action to advance the bit; avoid excessive force that could cause wear or bit breakage. After drilling each hole, withdraw the bit to clear debris, and check the hole depth and cleanliness before inserting fixings or anchors. Replace worn bits from the set to maintain drilling efficiency.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Match drill speed and hammer setting to the rotary hammer’s manual and to the hardness of the concrete. For prolonged repetitive drilling, allow bits to cool periodically and clear debris frequently to extend bit life and maintain consistent hole quality.
