Drill bits set Dedra 0703, 5 pieces, steel, for concrete/brick/stone/aerated concrete

Set of 5 Dedra 0703 drill bits made of steel, designed for drilling in concrete, brick, natural stone and aerated concrete. The kit contains a range of common masonry diameters to cover small to medium anchoring and fixture tasks. These masonry bits are intended for use with compatible hammer drills and rotary hammers and are suitable for construction, renovation and mounting applications where durable steel tips and fluted bodies are required to remove debris efficiently.

Advantages

The steel construction provides strength and resistance to wear during repetitive masonry drilling. Optimised flute geometry helps evacuate dust and debris from the hole to maintain drilling speed and reduce clogging. The set format offers multiple sizes to match various anchor plugs and fasteners, reducing the need to change tools frequently. These bits are compatible with standard SDS-plus or cylindrical chucks depending on the shank type and deliver consistent hole shape for reliable fixing performance.

Suitable for

• Drilling holes for anchors and wall plugs in concrete and brick
• Installing fixtures and fittings on masonry walls
• Preparing holes in natural stone and aerated concrete
• General construction, renovation and repair tasks involving masonry

Key specifications

• Material: steel cutting section and fluted body
• Intended materials: concrete, brick, natural stone, aerated concrete
• Set composition: five masonry drill bit sizes (various diameters for common anchoring tasks)
• Shank compatibility: suitable for use with compatible hammer drill or rotary hammer chucks
• Flute design: spiral flutes for efficient dust extraction

How to use

Fit a suitable bit from the set into a hammer drill or rotary hammer according to the tool manufacturer's instructions and secure the shank in the chuck. Select the correct drill diameter for the anchor or fastener to be used. Use hammer mode when drilling into concrete, brick or stone and apply steady pressure without forcing the bit. Periodically withdraw the bit to clear dust from the hole and allow the bit to cool if performing extended drilling. After finishing, clean the bits and store them in their case to prevent damage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling masonry. Match drill diameter to the anchor manufacturer's size recommendations and avoid excessive side load on the bit to maintain drilling accuracy and extend bit life.
