## Summary description

Single Dedra WPQ1031 drill bit with a 1 cm diameter and 135° point angle, designed for drilling into concrete, brick, stone and aerated concrete. Compatible with rotary and hammer drilling where masonry drilling is required. Suitable for renovation, construction and installation tasks that need precise holes in hard masonry materials.

## Long description

Dedra WPQ1031 drill bit with a 1 cm diameter and a 135° point angle is designed for drilling precise holes in hard masonry materials such as concrete, brick, natural stone and aerated concrete. This single-piece masonry bit is compatible with rotary and hammer drilling modes and is intended for tasks where controlled penetration and clean hole edges are required. The tool suits renovation, construction and installation work that requires repeatable results in common building substrates.
Advantages
The 1 cm diameter and 135° point angle provide a balance between cutting speed and hole accuracy, reducing walking and improving centring on tough surfaces. The bit’s geometry is optimised for masonry drilling, enabling efficient debris evacuation and consistent drilling progress. Being a single dedicated masonry bit, it is simple to fit and use with standard drill chucks that accept this shank size, and it is suitable for both professional and DIY applications where masonry materials are encountered.
Suitable for
Drilling holes for anchors and plugs in concrete and brick
Creating openings for through-fixings in natural stone and masonry
Preparing holes in aerated concrete for light installations and fixtures
Renovation and repair tasks that require repeatable, precise masonry holes
Key specifications

Compatible drilling modes: Rotary and hammer drilling for masonry
Suitable materials: Concrete, brick, stone, aerated concrete
Quantity: 1 piece
How to use
Secure the Dedra WPQ1031 drill bit in a drill with a compatible chuck and select the appropriate drilling mode for the material (hammer mode for solid masonry like concrete and rotary mode for softer stone or aerated concrete if required). Mark the drilling position and start at low speed to ensure correct centring, then increase speed and apply steady pressure suitable for the substrate. Periodically withdraw the bit to clear dust and debris for more efficient cutting and to avoid overheating. Use appropriate personal protective equipment such as safety glasses, gloves and dust mask when drilling masonry.
Usage recommendations
Use hammer drilling in reinforced concrete sparingly and avoid excessive force; let the bit’s geometry and the tool’s impact do the work. For prolonged drilling, pause occasionally to clear debris and allow the bit to cool. Match drill diameter to the size of anchors or plugs specified for the task to ensure secure fixings.
