Concrete SDS+ Drill Bit Dedra 25 mm WP2545

Dedra Concrete SDS+ Drill Bit 25 mm WP2545 is a purpose-built rotary hammer accessory designed for drilling clean, accurate holes in concrete, masonry and natural stone. This SDS+ shank drill bit fits SDS+ chucks and is intended for use with compatible rotary hammer systems to create holes for anchors, dowels and through-fixings in construction and renovation tasks.

Advantages

The drill bit features a 25 mm diameter optimized for standard anchor and dowel sizes and a working geometry that improves chip removal and reduces binding during drilling. Manufactured to maintain concentricity and tip durability, it delivers consistent hole dimensions and stable performance when used with appropriate SDS+ rotary hammers. Its standard SDS+ shank ensures quick, secure insertion and removal in compatible tool chucks.

Suitable for

• Drilling holes in reinforced and unreinforced concrete for anchors and dowels
• Masonry drilling for brick and block installations
• Preparing fixing points in renovation and construction projects
• Through-drilling for bolts and threaded rods in stone and concrete

Key specifications

• Diameter: 25 mm
• Shaft type: SDS+ compatible shank
• Intended materials: concrete, masonry, natural stone
• Typical application: anchor and dowel hole drilling, through-fixings

How to use

Select a rotary hammer with SDS+ chuck and set the tool to the appropriate hammer-drill mode if available. Mark the drilling point and secure the workpiece or area to prevent movement. Insert the SDS+ shank fully into the chuck and lock it according to the tool manufacturer’s instructions. Start drilling at low speed to establish a pilot position, then apply steady pressure while maintaining the drill perpendicular to the surface. Periodically withdraw the bit to clear dust and debris for improved cutting and cooling. For deep holes, use incremental drilling with intermittent clearing to maintain performance.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and gloves. Match drill diameter to the recommended anchor or dowel size and follow the anchor manufacturer’s installation instructions. Do not force the bit; allow the rotary hammer to deliver the impact energy. For reinforced concrete, use a bit and tool rated for hammer drilling through rebar when required.
