Drill bit Dedra WPQ06511 — 6.5 mm, for concrete/brick/stone/aerated concrete, 135° tip, 1 pc

Dedra WPQ06511 — 6.5 mm drill bit designed for drilling in concrete, brick, natural stone and aerated concrete. The single-piece bit has a 135° tip angle to provide precise material entry and reduce walking at the start of drilling. It is intended for use with hammer and rotary percussion drilling in construction, renovation and masonry tasks where a compact-diameter hole is required.

Advantages

The 6.5 mm Dedra WPQ06511 drill bit combines a hardened cutting tip with a geometry optimised for impact drilling, which improves drilling stability and extends tool life compared to standard twist bits. The 135° point angle enhances centring and reduces chipping on brittle materials. Supplied as a single unit, the bit is easy to replace and suitable for both professional tradespeople and DIY users performing targeted drilling tasks.

Suitable for

• Drilling anchor and screw holes in concrete and brick
• Creating fixing points in natural stone and masonry
• Drilling light structural holes in aerated concrete
• Use with hammer or rotary-percussion drills for renovation and construction

Key specifications

• Diameter: 6.5 mm
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Tip angle: 135° for improved centring and reduced walking
• Pack quantity: 1 piece
• Intended drilling mode: hammer and rotary percussion

How to use

Secure the Dedra WPQ06511 drill bit in a compatible drill chuck or SDS adapter according to your tool’s instructions. Mark the drilling position and, if necessary, pilot with a small marker hole. Start drilling at low speed to allow the 135° tip to centre, then increase speed and apply steady pressure appropriate for the material. For concrete and stone use the hammer or rotary percussion mode; for softer brick or aerated concrete use rotary mode or reduced impact to avoid overloading the bit. Withdraw the bit periodically to clear debris and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and hearing protection. Match drill speed and impact settings to the material being drilled, and replace the bit when wear degrades cutting performance to maintain clean holes and avoid tool overload.
