## Long description

Dedra WPQ1421 is a single 14 mm drill bit designed for drilling into concrete, brick, natural stone and aerated concrete. With a 135° point angle and a robust tip geometry, this masonry bit is intended for use with both rotary and hammer drilling modes, enabling precise hole making in construction and renovation tasks. Supplied as one piece, the bit is suitable for professional tradespeople and home users performing anchoring, fixture installation or service openings in mineral substrates.
Advantages
The 14 mm diameter delivers a standard hole size for many fasteners and anchors while the 135° point angle improves centring and reduces walking at the drill start. The carbide-tipped cutting face and reinforced shank provide wear resistance and stable drilling performance in hard mineral materials. Compatibility with hammer and rotary drilling expands the range of usable tools and speeds up work on masonry and concrete surfaces.
Suitable for
 Drilling fixing holes for anchors and sleeve plugs in concrete and brick
 Installing fittings, electrical boxes and plumbing penetrations through masonry
 Making pass-through openings for cabling and conduits in natural stone and aerated concrete
 General renovation tasks requiring accurate holes in mineral substrates
Key specifications
 Diameter: 14 mm
 Point angle: 135°
 Intended materials: concrete, brick, natural stone, aerated concrete
 Number of pieces: 1
 Usable with: rotary drilling and hammer drilling
How to use
Select a drill or rotary hammer compatible with a 14 mm masonry bit and secure the bit properly in the chuck. Mark the drilling location and, if necessary, use a centre punch or pilot mark to prevent walking. Start drilling at low speed to establish the hole, then apply steady pressure and increase speed according to the drill manufacturer's recommendations; use the hammer function for dense concrete and rotary mode for softer masonry when appropriate. Periodically withdraw the bit to clear dust and allow cooling; maintain straight alignment to achieve a clean, accurate hole.
Usage recommendations
Use appropriate personal protective equipment including safety glasses, dust mask and hearing protection. For reinforced concrete, check for rebar before drilling; reduce feed force when contacting metal and consider specialized bits for repeated reinforcement contact. Clean holes of dust before inserting anchors or fasteners to ensure proper fixation.
