Concrete drill bit DeWalt DT6505 Ø5 mm x 85 mm

DeWalt DT6505 Ø5 mm x 85 mm concrete drill bit is designed for drilling into concrete and masonry. The 5 mm diameter and 85 mm overall length make this bit suitable for creating holes for small anchors, dowels and through-holes for cable conduits. A carbide-tipped cutting head combined with a hardened steel shank ensures wear resistance and maintains straight drilling in demanding construction and renovation tasks.

Advantages

The carbide tip provides high hardness at the cutting edge for improved penetration into reinforced concrete and brick. The hardened steel body resists bending and wear, ensuring longer tool life under impact loads. Precision ground flute geometry promotes efficient dust removal and stable drilling performance. The bit is compatible with hammer drills and rotary hammers that accept standard round shanks, enabling versatile use on job sites and during repairs.

Suitable for

• Drilling holes for small expansion anchors and wall plugs
• Making passages for cable conduits and electrical installations
• Preparation of masonry and concrete surfaces for light fixtures or fittings

Key specifications

• Diameter: 5 mm
• Overall length: 85 mm
• Tip material: carbide-tipped cutting head
• Shank material: hardened steel
• Application: concrete and masonry

How to use

Secure the appropriate drill chuck and insert the bit until it is firmly seated. Use a hammer drill or rotary hammer in hammer mode for best results on concrete and masonry; on softer materials, rotary mode without impact can be used. Mark the drilling point, start at low speed to establish the pilot, then increase speed and apply steady pressure without forcing the bit. Periodically withdraw the bit to clear dust and prevent overheating, and ensure the drilled hole depth matches the anchor or dowel length.

Usage recommendations

Use personal protective equipment such as safety glasses, ear protection and dust mask. Match the drill speed and hammer setting to the material: high-impact settings for reinforced concrete, lower impact for softer masonry. Replace the bit when cutting performance declines or if the carbide tip is chipped to maintain clean, accurate holes.
