Drill bit Dedra WPQ2031, diameter 2 cm, 135° point, for concrete/brick/stone/aerated concrete, 1 pc

Single Dedra WPQ2031 masonry drill bit with a 2 cm diameter and a 135° point angle, designed for drilling into concrete, brick, natural stone and aerated concrete. This drill bit is supplied as one piece and is intended for use with hammer drills to create anchor and through holes in hard mineral materials. The geometry and cutting angle are tailored to ensure stable penetration and reduced walking on the surface before drilling begins.

Advantages

The Dedra WPQ2031 offers robust construction for consistent performance in mineral substrates. The 135° point angle provides improved centring and reduced chipping in brittle materials, while the 2 cm diameter delivers a standard anchoring size for many fixing applications. Supplied as a single unit, the bit is ready for immediate use and compatible with most hammer drill chucks designed for masonry bits.

Suitable for

• Drilling anchor holes for bolts and anchors in concrete
• Creating through-holes in brick and natural stone
• Preparing openings in aerated concrete for fixtures and installations
• General masonry drilling with hammer drills

How to use

Fit the Dedra WPQ2031 drill bit securely into a compatible hammer drill chuck. Mark the drilling position and start at low speed to establish the hole centre, then increase speed and use hammer action appropriate for the substrate. Apply steady axial pressure without forcing; withdraw the bit periodically to clear debris when drilling deep holes. For anchor holes, drill to the required depth and clean the hole before inserting anchors or fasteners.

Usage recommendations

Use personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. For prolonged drilling into hard concrete or stone, allow the bit to cool and remove accumulated dust frequently to maintain cutting efficiency. Match drill speed and hammer impact settings to the material to avoid premature wear.
