## Summary description

Dedra WP1441 is a single drill bit with a 1.4 cm diameter and 35 cm working length designed for drilling into concrete, brick, stone and aerated concrete. The bit suits rotary and hammer drills for deep anchoring, through-holes and installation of fasteners in masonry and similar construction tasks.

## Long description

Dedra WP1441 is a single masonry drill bit with a 1.4 cm diameter and a 35 cm working length, designed for drilling deep holes in concrete, brick, natural stone and aerated concrete. The bit is intended for use with rotary and hammer drills and provides the reach and rigidity needed for through-holes, anchoring and installation of fasteners in masonry and similar construction substrates.
Advantages
The Dedra WP1441 combines a long working length with a thick 1.4 cm diameter to enable deep anchoring and through-drilling without frequent repositioning. Its geometry and material are adapted for percussive drilling in hard masonry, offering efficient removal of drilling debris and stable guidance during drilling. Supplied as a single piece, the bit is suitable for on-site replacement and for jobs that require an extended reach compared with standard-length bits.
Suitable for
 Drilling anchor and through-holes in reinforced and non-reinforced concrete
 Creating holes for fasteners in brick and natural stone
 Drilling into aerated concrete blocks for installations
 Tasks requiring deep, straight holes with a 1.4 cm diameter
Key specifications
 Diameter: 1.4 cm
 Working length: 35 cm
 Compatible materials: concrete, brick, natural stone, aerated concrete
 Intended drill types: rotary drills and hammer drills
 Package quantity: 1 piece
How to use
Select a rotary or hammer drill with a compatible chuck or SDS adapter as required by the drill bit shank style. Mark the drilling point and, if necessary, use a punch to prevent bit walking on smooth surfaces. Begin at low speed to establish the hole, then apply percussive action or increased speed appropriate to the substrate while maintaining steady axial pressure. Periodically withdraw the bit to clear dust and debris to keep the hole clean and prevent overheating. After reaching the required depth, remove the bit and clean the hole before inserting anchors or fasteners.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling masonry. Match drilling speed and hammer action to the material to extend bit life, and avoid excessive side load or bending on the long shaft to prevent breakage. Store the bit in a dry place and inspect for wear or damage before reuse.
