Graphite cylindrical concrete drill bit 5 mm for masonry, model 57H313

Graphite cylindrical concrete drill bit 5 mm (model 57H313) is designed for drilling masonry and concrete. The bit features a cylindrical shank that ensures secure clamping in standard chucks and rotary drills, enabling precise small-diameter holes for anchors, dowels and wiring conduits. It is intended for renovation, installation and light-to-medium construction tasks where accurate, clean holes are required in mineral materials.

Advantages

The solid cylindrical shank provides stable mounting and reduces wobble during drilling, improving hole accuracy. A carbide tip and optimized flute geometry support effective removal of dust and debris, helping maintain drilling speed and prevent overheating. The 5 mm diameter is suitable for typical anchor and dowel sizes, while the compact length enables controlled, shallow drilling in confined spaces.

Suitable for

• Drilling holes in concrete for small anchors and dowels
• Creating passages for electrical conduits and wiring
• Renovation and repair works in masonry
• Light-to-medium installation tasks with rotary drills

Key specifications

• Material: carbide tip on high-strength steel body
• Shank type: cylindrical (smooth) for standard chucks
• Diameter: 5 mm
• Intended material: concrete, masonry and other mineral substrates
• Flute design: spiral for dust extraction

How to use

Secure the drill bit in the chuck of a rotary drill, ensuring the cylindrical shank is fully inserted and clamped. Mark the drilling point, start at low speed to establish the position, then increase speed and apply steady, moderate pressure. Periodically withdraw the bit to clear dust and prevent clogging; for deeper holes, use incremental drilling with frequent cleaning. Avoid excessive lateral force to prevent bit breakage and ensure a straight hole.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and dust mask. For reinforced concrete or very hard substrates, consider pre-drilling pilot holes with a suitable carbide masonry bit and use a hammer drill mode only if the bit and drill support percussion. Keep the bit cool by allowing short pauses during prolonged drilling and clear debris frequently to maintain cutting efficiency.
