Drill bit Dedra WPQ3060, diameter 30 mm, for concrete/brick/stone/aerated concrete, 135° point, 1 pc

The Dedra WPQ3060 percussion drill bit is a 30 mm-diameter masonry bit designed for creating larger holes in concrete, brick, natural stone and aerated concrete. It is intended for use with rotary hammers and SDS-compatible chucks where a robust, single-piece drill is required for drilling anchor, conduit and pipe feed holes. The 135° point geometry reduces chipping at the hole entry and helps maintain drilling alignment when beginning a large-diameter bore.

Advantages

The 135° point angle provides controlled cutting action and improved centring when starting holes in hard masonry. The solid construction and suitability for percussion drilling deliver longer service life under impact loads typical for concrete and brick work. Supplied as a single unit, the bit is ready for immediate use with compatible rotary hammers and minimizes the need for adapters or additional fittings.

Suitable for

• Drilling anchor and fixing holes in concrete and reinforced masonry
• Creating openings for pipes and electrical conduits in brick and aerated concrete
• Preparing holes for dowels and structural fastenings in natural stone

Key specifications

• Diameter: 30 mm
• Compatible materials: concrete, brick, stone, aerated concrete
• Tip angle: 135° point
• Intended use: percussion/rotary hammer drilling, SDS-style systems
• Quantity: 1 piece

How to use

Install the Dedra WPQ3060 bit into a compatible SDS-style chuck or rotary hammer spindle according to the tool manufacturer’s instructions. Secure the workpiece area and mark the drilling point. Start drilling at low speed to establish the centre, then apply steady pressure with the hammer action engaged for masonry work. Periodically withdraw the bit to clear dust and allow cooling during extended drilling. After completing the hole, retract the bit and inspect the hole for correct size and cleanliness.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust masks when drilling masonry. For reinforced concrete, ensure the bit is rated for occasional contact with reinforcement and reduce feed pressure if rebars are encountered. Match drill speed and hammer setting to material hardness; allow the bit to clear debris frequently to maintain cutting efficiency and prolong service life.
