## Long description

Dedra WPQ1441 is a single 1.4 cm diameter masonry drill bit engineered for rotary drilling in concrete, brick, stone and aerated concrete. The bit has a 135° point angle designed to improve penetration and reduce chipping at the entry point. Supplied as one piece, the Dedra WPQ1441 is intended for use in construction, renovation and installation tasks where reliable hole drilling in structural materials is required.
Advantages
The 135° tip geometry offers a balance of fast cutting and controlled breakthrough, helping to minimise spalling on brittle surfaces. A 1.4 cm diameter provides a common hole size for anchors and through-fixings in masonry. As a single-piece supply, the drill bit is ready for immediate use in rotary drilling tools compatible with masonry bits. The product is specified for common masonry substrates — concrete, brick, stone and aerated concrete — so users can expect consistent performance across these materials when correct drilling technique is applied.
Suitable for
Drilling anchor and fixing holes in concrete and brick
Preparing holes for through-fixings in stone and natural masonry
Installing fixtures and fittings in aerated concrete blocks
General construction and renovation drilling tasks requiring a 1.4 cm diameter
Key specifications
Diameter: 1.4 cm
Point angle: 135°
Compatible materials: concrete, brick, stone, aerated concrete
Quantity: 1 piece
Intended drilling mode: rotary drilling in masonry/structural materials
How to use
Select a drill or hammer drill suitable for masonry bits and secure the Dedra WPQ1441 in the tool chuck according to the tool manufacturer's instructions. Mark the drilling position and start drilling at low speed to establish the centre, then increase speed and apply steady axial pressure without excessive lateral force. Periodically withdraw the bit to remove dust and allow the bit to cool; when drilling deep holes, clear debris more frequently. Use appropriate personal protective equipment including eye and hearing protection and a dust mask when drilling masonry.
Usage recommendations
For best results, match drill speed and feed pressure to the material: lower speeds and moderate pressure for hard concrete, slightly higher speeds for softer brick and aerated concrete. Use a depth stop when installing anchors to ensure correct hole depth, and replace the bit when wear reduces cutting efficiency or if the tip becomes visibly damaged.
