Drill bit Dedra WP1846 — 1.8 cm diameter, 40 cm working length, for concrete/brick/stone/aerated concrete

Dedra WP1846 drill bit, with a 1.8 cm diameter and 40 cm working length, is designed for drilling into concrete, brick, natural stone and aerated concrete. The single-piece bit is intended for use with hammer drills and rotary hammers in construction and renovation tasks where deep or through holes are required. Its length and cutting geometry allow reaching reinforcement positions, installing anchors and creating passages for services while maintaining stable drilling performance.

Advantages

The drill bit features a long working length for deep drilling without changing tools, and a diameter that suits common anchor and through-hole requirements. Its tip and flute design provide effective removal of dust and debris during hammer drilling, reducing binding and improving progress in masonry materials. Made as a single, sturdy piece, the bit offers consistent alignment and resistance to bending under typical on-site loads.

Suitable for

• Drilling anchor and fixing holes in concrete and brick
• Creating through-holes for rebar inspection or conduit passages
• Drilling into natural stone and aerated concrete
• General masonry drilling with hammer drills and rotary hammers

Key specifications

• Diameter: 18 mm
• Working length: 400 mm
• Material compatibility: concrete, brick, natural stone, aerated concrete
• Design: single-piece construction suitable for hammer action
• Application: deep and through drilling for anchors, reinforcements and utilities

How to use

Select a compatible hammer drill or rotary hammer with the correct chuck or SDS interface for this type of bit. Mark the drilling point, secure the workpiece if possible, and start drilling at low speed to position the tip. Apply steady pressure and allow the hammer action to perform most of the work; withdraw periodically to clear dust for deep holes. Use appropriate personal protective equipment (eye protection, gloves, dust mask) and follow machine manufacturer safety instructions.

Usage recommendations

For optimal performance, use the bit on materials within its stated compatibility and avoid excessive lateral forces. When drilling long depths, withdraw the bit regularly to clear debris and reduce heat build-up. Match bit diameter to anchor or sleeve size and use corrosion-resistant anchors in exposed environments.
