Drill bit 8 mm Dedra WPQ0816 for concrete, brick and stone, 135° point, 1 pc

Dedra WPQ0816 drill bit, 8 mm diameter, is designed for drilling in concrete, brick, natural stone and aerated concrete. The bit features a 135° point angle that improves centering when starting holes and reduces walking on hard surfaces. Supplied as a single piece, this masonry drill bit is suitable for use with percussion and rotary hammer drills as well as standard rotary drills when occasional impact is required.

Advantages

The 135° point provides accurate positioning and faster hole starts while reducing chipping on tiles and fragile masonry. The 8 mm diameter offers a balance between precision and material removal for typical fastening and anchor installations. Constructed for impact and rotary drilling, the bit delivers consistent performance in a range of masonry materials and maintains cutting geometry for reliable hole quality.

Suitable for

• Drilling holes for anchors and screws in concrete and brick
• Installing fixtures in natural stone and masonry facades
• Creating through-holes or pilot holes in aerated concrete blocks
• Light renovation and construction tasks requiring percussive drilling

Key specifications

• Diameter: 8 mm
• Point angle: 135° for improved centering
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Intended drilling modes: percussive (hammer) and rotary drilling
• Quantity: 1 piece

How to use

Select a drill and mode appropriate for the material—use hammer/percussion mode for concrete and dense masonry, or rotary mode for softer stone and aerated concrete. Mark the drilling position, start at low speed to ensure the 135° point locates accurately, then increase speed and apply steady pressure. Withdraw the bit periodically to clear dust and avoid overheating; use water only if the drill and bit specification allow it. Secure fixtures after verifying hole diameter and depth match the fastener requirements.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and clamp or support workpieces where possible. For best results in reinforced concrete, check for rebar before drilling and use a dedicated rebar-cutting bit if required. Replace the bit when wear degrades centering or drilling speed.
