## Long description

Dedra WPQ1241 drill bit, 12 mm diameter, is designed for drilling into concrete, brick, natural stone and aerated concrete. This single-piece masonry bit features a 135° point angle that improves centre-punching accuracy and reduces splitting on brittle materials. Suitable for both rotary and hammer drilling modes, the Dedra WPQ1241 is a general-purpose choice for construction and renovation tasks where a reliable masonry bit is required.
Advantages
The 135° point provides stable centring and minimises wandering at drill start, which helps achieve precise holes without extra pilot drilling. The one-piece construction offers consistent performance and resistance to bending under typical masonry loads. A 12 mm diameter is a common size for anchors, plugs and through-holes in brick and concrete, making this bit versatile for many onsite tasks. The bit is optimised for use with hammer drills and rotary hammers in masonry applications.
Suitable for
Drilling anchor and plug holes in concrete and brick
Preparing openings for through-bolts and fixings in stone
Installing fixtures in aerated concrete blocks
General masonry drilling during renovation and construction
Key specifications
Diameter: 12 mm
Point angle: 135° for improved centring
Material compatibility: concrete, brick, natural stone, aerated concrete
Design: single-piece masonry drill bit
Intended drilling modes: rotary drilling and hammer (percussion) drilling
How to use
Secure the drill bit in the appropriate chuck of a rotary drill or hammer drill according to the tool manufacturer's instructions. Select hammer mode for dense concrete or rotary mode for lighter masonry and aerated concrete if your tool allows switching. Mark the drilling point, apply steady axial pressure, and start drilling at low speed to ensure the 135° point centres correctly. Increase speed and, if needed, use short breaks to clear dust from the hole. When drilling deep holes, periodically withdraw the bit to remove debris and prevent overheating.
Usage recommendations
Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling masonry. For reinforced concrete avoid excessive side pressure and consult the anchor or fixing manufacturer's recommendations for hole diameter and depth. Match the 12 mm diameter to compatible anchors and plugs to ensure a secure fit.
