Drill bit Dedra WXQ3069, diameter 3 cm, for concrete/brick/stone/aerated concrete, 135° point angle, 1 pc

Single Dedra WXQ3069 drill bit with a 3 cm diameter designed for drilling in concrete, brick, natural stone and aerated concrete. The bit has a 135° point angle that supports efficient penetration and controlled chipping when creating larger-diameter holes in masonry materials. Supplied as one piece, this heavy-duty masonry drill bit is intended for situations where a wider bore is required for installations and building tasks.

Advantages

The 3 cm diameter provides a wide hole in a single pass, reducing the need for step drilling. A 135° point angle improves centring and helps prevent walking on hard surfaces. The tip geometry and robust body are suited to repeated use in abrasive materials like concrete and brick. Supplied as a single unit, the bit is easy to store and replace in drill chucks configured for masonry work.

Suitable for

• Drilling large-diameter anchor and fixing holes in concrete and brick
• Creating openings for pipes or conduits in natural stone and aerated concrete
• Preparing rough, structural penetrations for construction and renovation tasks

Key specifications

• Diameter: 3 cm
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Point angle: 135°
• Quantity in package: 1 piece

How to use

Secure the drill bit in a compatible rotary or rotary-percussion drill chuck rated for masonry bits. Mark the drilling position and start at low speed to establish the centre before increasing speed and applying steady, even pressure. For concrete and other hard materials use short, controlled drilling intervals to avoid overheating and to remove debris from the hole. Where applicable, use a hammer function for efficient penetration and periodically withdraw the bit to clear dust and chips.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection and dust mask. Match drill speed and feed pressure to the material: lower speed and higher percussion for hard concrete, moderate speed for aerated concrete. Keep the bit cool by pausing periodically and clearing debris to preserve tip geometry and prolong service life.
