Drill bit Dedra WB10020 — 10 mm diameter, 200 mm length, for concrete, brick, stone, aerated concrete

Dedra WB10020 percussion drill bit, 10 mm diameter and 200 mm working length, is designed for drilling clean, accurate holes in concrete, brick, natural stone and aerated concrete. The single-piece SDS‑plus-compatible shank fits most hammer drills and rotary hammers that accept SDS‑plus accessories, enabling efficient transfer of percussion energy for fast penetration and consistent hole quality during anchor and fastening preparation.

Advantages

The solid construction and optimized tip geometry provide reliable chip evacuation and reduced wandering at the start of drilling. Compatibility with SDS‑plus systems ensures secure retention in the tool chuck and minimizes slippage under load. The 200 mm length gives extended reach for deep anchor holes while the 10 mm diameter matches common anchor and rebar starter sizes used in masonry and construction applications.

Suitable for

• Drilling anchor and fastening holes in concrete
• Preparing openings for plugs in brick and blockwork
• Creating holes for through-fixings in natural stone
• Drilling in aerated concrete where controlled depth is required

Key specifications

• Diameter: 10 mm
• Overall/working length: 200 mm
• Shank type: SDS‑plus compatible
• Intended materials: concrete, brick, natural stone, aerated concrete
• Construction: single-piece percussion drill bit

How to use

Insert the bit into an SDS‑plus hammer drill or rotary hammer, ensuring it locks securely. Mark the drilling position, start at low speed to establish the guide, then apply steady pressure and engage the hammering mode for masonry materials. Withdraw the bit periodically to clear dust and chips for deeper holes. Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask when drilling.

Usage recommendations

For best results when installing anchors, match the 10 mm drill hole to the specified anchor diameter and observe recommended drilling depth. Select drill speeds and feed rates suitable for the base material: slower feed and continuous hammer action for hard concrete, moderate feed for brick and aerated concrete. Replace the bit when wear increases wobble or reduces cutting efficiency.
