## Long description

Dedra WPQ05511 is a 5.5 mm masonry drill bit engineered for hammer and percussion drills. Designed to bore into concrete, brick, natural stone and aerated concrete, this single-piece bit features a 135° point angle that improves centring and minimises walking when starting holes on hard surfaces. It is intended for common anchoring and fixture installation tasks such as drilling for anchors, conduits, wiring and mounting hardware.
Advantages
The 135° point reduces bit skidding and helps achieve accurate hole placement without additional centre-punching. Its geometry balances penetration rate and chip evacuation for efficient drilling in dense masonry materials. Supplied as an individual unit, the bit is compact and simple to store or carry in a small kit or tool bag. Compatibility with hammer and percussion drills allows use on a wide range of standard drilling equipment.
Suitable for
Drilling anchor holes in concrete and brick
Installing conduits and electrical boxes in masonry walls
Fixing fixtures and fittings to stone or aerated concrete
General-purpose masonry drilling with hammer/percussion drills
Key specifications

How to use
Select an appropriate hammer or percussion drill and secure the bit in the chuck according to the drill manufacturer's instructions. Mark the drilling location and, if necessary, use a low-speed pilot start to locate the tip before increasing to the recommended drilling speed. Apply steady, moderate pressure; allow the drill and bit to do the work. Withdraw periodically to clear debris and prevent clogging when drilling deeper holes. For reinforced concrete, check for rebar and adapt technique or tools as needed.
Usage recommendations
Wear eye and hearing protection and a dust mask when drilling masonry. Use correct drill speed and hammer settings for the material, avoid excessive side force, and replace the bit if signs of wear or reduced cutting performance appear to maintain safe and accurate results.
