SDS+ concrete drill bit Dedra WPQ2260 22 mm

The SDS+ concrete drill bit Dedra WPQ2260 22 mm is designed for drilling holes in concrete and masonry using rotary and hammer drills with SDS+ chucks. Its 22 mm diameter and purpose-built flute geometry ensure reliable centering on the work surface and effective removal of dust and debris from the hole. The bit is intended for standard construction and installation tasks such as making through-holes, fixing anchors and dowels, and preparing openings for pipe and conduit passes.

Advantages

The drill bit combines an SDS+ shank for secure, vibration-resistant coupling with a carbide-tipped head that maintains cutting performance when working with reinforced concrete and hard masonry. Its flute profile facilitates fast chip evacuation, reducing friction and heat build-up during continuous drilling. The 22 mm size offers a balance between hole strength and material removal rate, suitable for common anchor and fastening systems used in construction.

Suitable for

• Drilling through concrete walls and floors for anchors and dowels
• Creating openings for pipes, conduits and sleeves in masonry
• Installation of anchors, bolts and mechanical fixings in structural and non-structural elements

Key specifications

• Shank type: SDS+ for hammer and rotary hammer drills
• Tip material: carbide-tipped cutting head for durability
• Diameter: 22 mm nominal drilling diameter
• Intended materials: concrete, reinforced concrete, brick and general masonry
• Flute design: spiral flute for efficient dust removal

How to use

Install the SDS+ shank into the drill’s chuck until it locks securely. Select hammer mode for concrete and masonry; use rotary-only mode for delicate or non-hammer applications. Begin drilling at low speed to establish a centered starting point, then increase to the recommended speed for your drill and bit diameter. Apply steady axial pressure without forcing the bit; allow the drill and carbide tip to cut naturally. Periodically withdraw the bit to clear dust and prevent clogging when drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection and dust mask when drilling. Match the 22 mm hole diameter to the corresponding anchor or sleeve size and verify drill speed and feed pressure according to the drill manufacturer's guidance. For reinforced concrete, drill interruptions and gradual advancement help preserve the carbide tip and extend bit life.
