Drill bit Dedra WPQ25T00, 25 mm diameter, for concrete/brick/stone/aerated concrete, 135° point, 1 pc

Dedra WPQ25T00 is a single 25 mm diameter drill bit designed for use with rotary hammers and heavy-duty drills. Intended for drilling in concrete, brick, natural stone and aerated concrete, this bit features a 135° point angle that improves penetration and helps clear dust from the hole during drilling. Supplied as one piece, the bit is suitable for on-site construction work, masonry repair and installation tasks where a 25 mm hole is required.

Advantages

The 135° point reduces walking at the drill start and provides stable guidance when penetrating hard materials. Designed for hammer drilling, the WPQ25T00 delivers controlled cutting action in dense substrates while maintaining hole roundness. The single-piece supply simplifies ordering and inventory for projects that need individual replacement bits.

Suitable for

• Drilling anchor and dowel holes in concrete and brick
• Installing pipe and cable passages through masonry
• Repairing and retrofitting masonry elements
• Creating holes in aerated concrete blocks for fixtures

Key specifications

How to use

Install the Dedra WPQ25T00 into a compatible rotary hammer or hammer drill according to the tool manufacturer's instructions. Use appropriate drill speed and hammer setting for the substrate: engage hammer action when drilling concrete, brick or stone; reduce feed pressure to avoid bit breakage. Periodically withdraw the bit to clear dust and debris from the hole and allow cooling. After drilling, inspect the hole for required diameter and clean before inserting anchors or pipes.

Usage recommendations

Always wear suitable personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. Use a depth stop or mark the bit to control hole depth and select the proper drill chuck or SDS adapter that fits the bit shank. For prolonged drilling in reinforced concrete, consider using a bit designed specifically for rebar contact or use a slower feed with intermittent withdrawal to extend bit life.
