## Summary description

Dedra WPQ1231 is a 12 mm masonry drill bit designed for drilling concrete, brick, stone and aerated concrete. It features a 135° point angle for controlled entry and reduced chipping. Supplied as a single piece, the bit is suited for rotary and hammer drilling tasks in construction, installation and repair work.

## Long description

Dedra WPQ1231 is a 12 mm masonry drill bit developed for drilling into concrete, brick, natural stone and aerated concrete. The bit is supplied as a single piece and is compatible with rotary drilling as well as hammer drilling modes typically found in SDS-plus and standard chuck drills that accept straight-shank bits of this diameter. The 135° point angle improves centring and reduces spalling at the entry, making it suitable for installation, construction and repair tasks that require precise, clean holes.
Advantages
The 135° tip geometry provides a controlled entry into hard materials, minimising chip formation and helping to keep the drill bit stable during startup. A 12 mm diameter offers a common, versatile hole size for anchors, dowels and through-fixings. Supplied as one robust piece, the bit is ready for immediate use and convenient to store with other masonry accessories.
Suitable for
 Drilling anchor and plug holes in concrete and brick
 Creating passage holes for cables and conduits in masonry
 Installing fixings for shelving, frames and fixtures on stone or aerated concrete
 Repair and renovation works that require accurate, clean holes
Key specifications
 Diameter: 12 mm
 Point angle: 135° for controlled entry
 Compatible materials: concrete, brick, natural stone, aerated concrete
 Quantity: 1 piece
 Intended drilling modes: rotary and hammer drilling
How to use
Secure the drill bit in a compatible drill chuck, ensuring firm seating. Select hammer mode for dense concrete and stone, or rotary mode for softer masonry where available. Mark the drilling point, start at low speed to establish the centre, then increase speed and apply steady pressure. Periodically withdraw the bit to clear dust and prevent overheating. Use appropriate personal protective equipment including eye protection, gloves and dust mask when drilling masonry.
Usage recommendations
For best results, match drill speed and hammer action to the material: use moderate to high hammer energy for reinforced concrete and lower impact for aerated concrete to avoid overbreak. Use the 12 mm size with correctly rated anchors and plugs, and pre-check substrate condition before installing fixings.
