Drill bit GRAPHITE SDS+ 8 mm for concrete (T 57H418)

GRAPHITE SDS+ 8 mm drill bit for concrete (model T 57H418) is a masonry drill bit engineered for use with SDS+ rotary hammer drills. With an 8 mm diameter and a design intended for concrete and brick, this bit provides precise holemaking for construction, installation and repair jobs. The bit’s flute geometry and tip shape are optimized for chip removal and controlled penetration in masonry materials.

Advantages

The SDS+ shank ensures secure tool-bit connection and quick bit changes without additional adapters, while the hardened tip improves wear resistance during repetitive drilling in concrete and brick. Its 8 mm diameter offers a balance between compact hole size and structural suitability for anchors and fasteners. The flute profile facilitates efficient dust evacuation, reducing binding and heat buildup for more consistent drilling performance.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Installing fixtures in brick and masonry walls
• Electrical and plumbing outlet preparations in masonry
• General construction and renovation tasks requiring precise masonry holes

Key specifications

• Shank type: SDS+ compatible
• Point diameter: 8 mm
• Material compatibility: concrete, brick and common masonry
• Design: fluted body for chip removal and controlled drilling

How to use

Insert the SDS+ shank into the rotary hammer drill’s chuck until it locks. Select the rotary hammer mode appropriate for drilling in masonry. Start drilling at low speed to position the tip, then increase speed and apply steady pressure without forcing the bit. Periodically retract the bit to clear dust from the hole and maintain efficient cutting. Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling masonry.

Usage recommendations

For best results in reinforced concrete, use a dedicated carbide-tipped masonry bit and avoid excessive side load. Match hole diameter to the anchor or fastener specifications and keep the drill perpendicular to the surface for accurate, clean holes.
