Drill bit Dedra WP1626, diameter 1.6 cm, working length 20 cm, for concrete/brick/stone/aerated concrete

Single Dedra WP1626 drill bit with a diameter of 1.6 cm and a working length of 20 cm, designed for drilling into masonry materials such as concrete, brick, natural stone and aerated concrete. The bit is intended for use with rotary and percussion drilling modes and is supplied as a single piece suitable for both professional and DIY applications where precise holes for wiring, anchors and fastenings are required.

Advantages

The Dedra WP1626 drill bit is engineered to provide consistent hole quality in hard building materials while maintaining stability during rotary and hammer drilling. Its 1.6 cm diameter and extended 20 cm working length allow drilling to depth without frequent bit changes, which is useful for installing anchors, conduits and through-holes. Supplied as a single unit, the bit is compact for storage and straightforward to replace when worn.

Suitable for

• Drilling anchor and fastening holes in concrete and brick
• Creating passages for electrical wiring and conduits in masonry
• Forming holes for plumbing or ventilation penetrations in aerated concrete
• Preparation of installation points in natural stone and blockwork

How to use

Fit the Dedra WP1626 drill bit securely into a compatible drill chuck or SDS adapter according to the drill manufacturer’s instructions. Select the appropriate drilling mode — rotary for light materials or percussion for harder masonry — and mark the drilling position. Start drilling at low speed to create a guide and then increase speed and apply steady pressure. Periodically withdraw the bit to clear dust and debris to maintain drilling efficiency and avoid overheating. Replace the bit when wear affects hole quality or drilling performance.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask, gloves) and ensure the workpiece is securely supported. For deep holes, clear debris regularly and allow the bit to cool. Match drill speed and hammer action to the material; reduce hammer action for aerated concrete and increase it for dense concrete or stone. Store the bit dry and protected from impacts to prolong service life.
