## Long description

Dedra WP1631 is a single 16 mm diameter drill bit with a 250 mm working length designed for impact drilling in concrete, brick, natural stone and aerated concrete. Designed for use with rotary hammers and SDS-plus chucks, this masonry drill bit provides the reach and rigidity required for creating deep anchor and service holes. The WP1631 is intended for applications such as fastening anchor bolts, installing pipe sleeves and through-holes where a consistent 16 mm bore is needed.
Advantages
The Dedra WP1631 offers a long 250 mm working length that enables drilling deep into masonry without the need for extensions. Its 16 mm diameter and compatible shank ensure secure seating in SDS-plus chucks for reliable power transfer during impact drilling. The bit geometry is optimised for masonry materials, allowing efficient material removal and stable drilling in concrete, brick, stone and aerated concrete.

How to use
Secure the Dedra WP1631 in an SDS-plus rotary hammer according to the tool manufacturer's instructions. Mark the drilling position and start at low speed to establish a pilot seat, then apply steady pressure while engaging the hammer mode for masonry. Maintain a straight drilling axis and periodically withdraw the bit to clear dust and debris for continuous efficient cutting. For through-holes, check alignment from both sides if accessible.
Usage recommendations
Use appropriate personal protective equipment, including safety glasses, hearing protection and a dust mask when drilling masonry. Select an SDS-plus rotary hammer with sufficient power for the material and hole depth. For reinforced concrete, avoid prolonged continuous drilling at the same spot and verify the bit condition regularly; replace the bit if wear reduces performance or if the tip is damaged.
