Drill bit Dedra WXQ2592, diameter 2.5 cm, 135° point angle, for concrete/brick/stone/aerated concrete

Dedra WXQ2592 drill bit with a 2.5 cm diameter and a 135° point angle is designed for rotary and percussion drilling in masonry materials. Built for use in concrete, brick, natural stone and aerated concrete, this single-piece drill bit provides a precise bore for construction and renovation tasks that require durable, reliable performance in hardened substrates.

Advantages

The 135° point angle improves centering and reduces walking at drill start, enabling accurate hole placement. The 2.5 cm diameter creates wide bores for anchors, through-fixings and large-diameter dowels. Engineered for rotary and hammer modes, the bit is optimized to withstand repeated impacts and abrasive contact with masonry materials while maintaining cutting efficiency.

Suitable for

• Drilling anchor and fixing holes in concrete and brick
• Preparing passages for large dowels and sleeves in masonry
• Work on natural stone and aerated concrete blocks
• Construction and renovation tasks requiring robust masonry drilling

Key specifications

• Diameter: 2.5 cm
• Point angle: 135° for improved centering
• Compatible drilling modes: rotary and percussion (hammer) drilling
• Intended materials: concrete, brick, natural stone, aerated concrete
• Pack quantity: 1 piece

How to use

Fit the drill bit securely into a compatible chuck, ensuring the shank type matches the drill. Select the appropriate speed and, if available, the hammer function for concrete or dense masonry. Start drilling at low speed to establish the position, then increase speed and apply steady pressure; avoid excessive axial force to reduce bit wear. Periodically withdraw the bit to clear dust and debris from the hole and to allow the bit to cool during prolonged drilling.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask, hearing protection) and follow drill manufacturer guidelines. For cleaner holes and longer bit life, use a vacuum extraction or blow out dust with compressed air. Match drill speed and hammer action to the material: use rotary-only for softer stone and hammer mode for dense concrete and brick.
