Drill bit Dedra WPQ1626, diameter 1.6 cm, for concrete/brick/stone/aerated concrete, 135° point, 1 pc

Single Dedra WPQ1626 drill bit with a 1.6 cm diameter designed for drilling in concrete, brick, natural stone and aerated concrete. The bit features a 135° point angle to improve penetration and control chipping when starting holes. Supplied as one piece, this masonry drill bit is intended for tasks such as anchor and dowel installation, structural repair and general masonry drilling where a robust carbide-tipped bit is required.

Advantages

The 135° point angle reduces wandering at the hole start and directs cutting forces for cleaner entry into hard materials. A 1.6 cm diameter provides a larger bore suitable for heavy anchors and fixings. The single-piece supply allows immediate replacement or use as a spare for professional and DIY toolkits. The design is compatible with standard rotary and hammer drilling machines when used with appropriate chucks and settings.

Suitable for

• Drilling anchor holes for bolts and dowels in concrete and brick
• Creating openings for through-fixings in masonry and natural stone
• Preparing holes for structural repair and retrofit fastening
• Drilling into aerated concrete blocks for plumbing or electrical fixings

Key specifications

• Diameter: 1.6 cm
• Point angle: 135° for controlled penetration
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Package quantity: 1 piece

How to use

Secure the drill bit in a compatible chuck according to the drilling machine manufacturer’s instructions. Select an appropriate drill mode (rotary hammer for hard masonry is recommended) and set the correct speed and impact setting for the material. Mark the drilling position, start at low speed to establish the hole, then apply steady pressure and increase speed as appropriate. Withdraw the bit periodically to clear dust and avoid overheating. After drilling, clean the hole before inserting anchors or dowels.

Usage recommendations

Use suitable personal protective equipment — safety glasses, dust mask and hearing protection — and follow the drill and bit manufacturer's guidance. For long life, avoid excessive lateral force and operate the bit at recommended speeds; use a hammer drill for dense concrete and reduce impact for aerated concrete to prevent overbreak.
