Drill bit Dedra WPQ1526, diameter 15 mm, for concrete/brick/stone/aerated concrete, 135° tip

Dedra WPQ1526 is a single 15 mm masonry drill bit engineered for drilling precise holes in concrete, brick, natural stone and aerated concrete. The bit has a 135° tip angle that provides controlled penetration, reduces chipping and helps maintain hole shape when used with hammer drills or rotary hammers. Its construction is tailored to common construction and renovation tasks that require a consistent 15 mm diameter.

Advantages

The 135° tip angle delivers stable drilling behavior and minimizes splitting of brittle materials. Designed for use in masonry, the bit combines adequate tip geometry with a shaft compatible with standard drill chucks and SDS-plus style hammering actions, allowing effective transfer of percussive energy for faster progress in hard substrates. Supplied as a single unit, it is convenient for targeted jobs where a specific 15 mm hole is required.

Suitable for

• Drilling anchor or dowel holes in concrete and brick
• Creating passage holes for cables or pipes in masonry walls
• Fixing fixtures to natural stone or blockwork
• Renovation and construction tasks requiring precise 15 mm holes

Key specifications

• Diameter: 15 mm
• Point angle: 135°
• Intended materials: concrete, brick, natural stone, aerated concrete
• Unit quantity: 1 piece

How to use

Select an appropriate drill or hammer drill compatible with masonry bits and securely clamp the Dedra WPQ1526 in the chuck or SDS holder according to the tool type. Mark the drilling location and start at low speed to position the tip, then apply steady pressure and increase speed or hammer action as needed for the material. Periodically withdraw the bit to clear dust and allow cooling. For deeper holes, clear debris more frequently to maintain drilling efficiency and prevent bind-up.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and a dust mask. Match drilling mode (rotary or hammer) to the substrate and avoid excessive lateral force to prolong bit life. For reinforced concrete, verify rebar positions before drilling and consider using a bit designed specifically for reinforced material if frequent rebar contact is expected.
