Drill bit Dedra WP1680 — 1 pc, diameter 1.6 cm, working length 74 cm, for concrete/brick/stone/aerated concrete

Dedra WP1680 drill bit — single-piece masonry bit with a diameter of 1.6 cm and a working length of 74 cm, designed for drilling deep holes in concrete, brick, natural stone and aerated concrete. The bit is intended for rotary and hammer drilling tools that accept this shank size and is suited to tasks requiring extended reach and stable penetration through dense masonry materials.

Advantages

The Dedra WP1680 offers a long working length that enables deep drilling without the need for extensions, reducing setup time on-site. Its 1.6 cm diameter is optimized for medium-to-large anchor and through-hole applications in masonry. The geometry and material of the cutting tip provide consistent drilling performance in concrete and natural stone while maintaining durability during repeated use. Compatibility with rotary and hammer drilling modes increases its versatility across renovation and construction tasks.

Suitable for

• Drilling deep anchor and through-holes in reinforced and unreinforced concrete
• Creating openings in brick walls for services and fastenings
• Boring holes in natural stone for fixtures or anchors
• Working in aerated concrete where long reach is required

Key specifications

• Diameter: 1.6 cm
• Working length: 74 cm
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Quantity: 1 piece
• Suitable drill modes: rotary and hammer drilling (where tool accepts shank)

How to use

Secure the Dedra WP1680 into the chuck of a drill or hammer drill that supports the bit's shank size and select the appropriate drilling mode for the material. Mark the drilling position and start at low speed to establish the pilot groove, then increase speed and apply steady pressure to maintain forward progress. For deep holes, periodically withdraw the bit to clear dust and debris, which helps maintain cutting efficiency and prevents overheating. Follow the drill manufacturer’s guidance for optimal RPM and feed pressure for the specific material.

Usage recommendations

Use personal protective equipment such as safety glasses, hearing protection and dust mask when drilling masonry. When drilling reinforced concrete, check for reinforcing bars and adjust technique or use appropriate bits if metal is present. For long continuous drilling sessions, allow occasional cooling pauses and clean the flutes to extend the bit's service life.
