Drill bit Dedra WPQ0721 — 7 mm, for concrete/brick/stone/aerated concrete, 135° point, 1 pc

Dedra WPQ0721 is a percussion drill bit with a 7 mm diameter and a 135° point angle, engineered for rotary‑percussion drilling in masonry and structural materials. Supplied as a single piece, this drill bit is intended for creating anchor holes, through‑holes and general repair openings in concrete, brick, natural stone and aerated concrete. The 135° tip geometry supports stable centring and controlled chip removal in impact drilling applications.

Advantages

The Dedra WPQ0721 drill bit offers consistent drilling performance in hard and porous masonry thanks to its diameter and point geometry. Its construction is optimized for percussion (hammer) drilling, providing improved penetration rates compared with standard twist bits when used in suitable tools. Delivered as an individual unit, the bit is convenient for targeted repair tasks or for carrying a small on‑site selection of sizes without excess packaging.

Suitable for

• Drilling anchor holes in concrete and brick
• Creating through‑holes for pipes and cables in masonry
• General repair and renovation work on stone and aerated concrete

Key specifications

• Diameter: 7 mm
• Point angle: 135°
• Intended drilling method: rotary‑percussion (hammer drilling)
• Suitable materials: concrete, brick, natural stone, aerated concrete
• Quantity in package: 1 piece

How to use

Select a compatible rotary‑percussion drill or hammer drill with the correct chuck capacity for a 7 mm bit. Mark the drilling position, secure the workpiece or ensure site safety, and start drilling at low speed to establish the hole before applying percussion mode and steady pressure. Use intermittent extraction to remove dust from the hole and avoid overheating the bit during extended drilling. After completing the hole, clean any residual dust before inserting anchors or passing through services.

Usage recommendations

For best results, use the Dedra WPQ0721 with a hammer‑drill rated for masonry and select appropriate drill speed and percussion settings for the material. Wear eye and respiratory protection to guard against dust when drilling concrete, brick or aerated concrete. Replace the bit if tip wear or chipping reduces drilling efficiency.
