Drill bit GRAPHITE 6 mm solid carbide for concrete, cylindrical shank (57H330)

GRAPHITE drill bit 6 mm solid carbide for concrete with a cylindrical shank is designed for producing precise holes in masonry and concrete. The solid carbide tip and reinforced body provide improved wear resistance and maintain cutting geometry during repeated drilling in abrasive materials. The straight (cylindrical) shank fits standard hand drills and rotary hammers that accept straight shanks, making it suitable for a wide range of drilling tools used in construction and renovation tasks.

Advantages

The solid carbide construction delivers high hardness and thermal stability to resist wear when drilling concrete and masonry. A precisely ground tip ensures accurate centring and clean hole edges with reduced chipping. The cylindrical shank offers compatibility with drills that require straight shanks and provides secure seating in standard chucks. The robust design supports consistent drilling performance and prolonged tool life under typical jobsite conditions.

Suitable for

• Drilling anchor and fastening holes in concrete and masonry
• Preparing openings for electrical boxes and conduit in walls
• Renovation and repair work involving drilling into brick, block, and reinforced concrete

Key specifications

• Material of cutting tip: solid carbide for improved wear resistance
• Drill diameter: 6 mm for standard anchor and fastener sizes
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Intended use: drilling into concrete and masonry
• Typical applications: anchors, fasteners, installations, and preparatory wall work

How to use

Mark the drilling position and secure the workpiece if possible. Use an appropriate drill or rotary hammer that accepts cylindrical shanks; select a steady drilling speed and apply consistent pressure. Start drilling at a low speed to establish the hole and then increase speed as the bit bites into the material. Periodically withdraw the bit to clear dust and debris to maintain cutting efficiency and prevent overheating. For deep holes, remove accumulated debris frequently to preserve bit performance.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection, and gloves. For reinforced concrete, ensure the bit is suitable for contact with rebar; reduce feed pressure and use intermittent drilling to avoid damage. Replace the bit when wear or chipping affects drilling accuracy or increases effort.
