Drill bit Dedra WB12020 — diameter 12 mm, length 200 mm, for concrete/brick/stone

Dedra WB12020 drill bit, single piece with a 12 mm diameter and 200 mm overall length, is engineered for drilling in concrete, brick, natural stone and aerated concrete. The bit is intended for use with SDS-plus or rotary hammer drills (confirm compatibility with your tool). Its length and diameter provide deep penetration required for masonry anchoring, conduit and pipe runs, and structural installations where a reliable hole profile is needed.

Advantages

The solid construction and correct geometry of the cutting head produce consistent drilling performance in masonry materials while minimising bit wander. A 200 mm length enables deeper holes without changing to extension accessories. Designed for single-piece supply, the bit offers straightforward selection and replacement. Compatibility with common SDS-plus systems ensures secure connection to the hammer mechanism and efficient energy transfer during impact drilling.

Suitable for

• Drilling anchor holes in concrete and brick
• Making conduit and pipe runs through masonry
• Installing anchors and rawl bolts for structural fixings
• Creating holes in natural stone and aerated concrete for mechanical fixings

Key specifications

• Diameter: 12 mm
• Total length: 200 mm
• Material suitability: concrete, brick, natural stone, aerated concrete
• Connection type: compatible with SDS-plus rotary hammer systems (confirm with tool before use)
• Quantity: 1 piece

How to use

Fit the Dedra WB12020 drill bit securely into the chuck or SDS-plus holder of a suitable rotary hammer or hammer drill, following the tool manufacturer's instructions. Select the hammer drilling mode for masonry. Start drilling at low speed to establish the hole, then apply steady pressure and allow the hammer action to do the work. Withdraw the bit periodically to clear dust and debris, especially when drilling deep holes. Use appropriate personal protective equipment including eye and ear protection, and take site-appropriate precautions for dust control.

Usage recommendations

For best results, verify SDS-plus compatibility with your drill, use water or dust extraction where required by material and site regulations, and select correct anchor diameter and embedment depth based on the drilled hole and fixing manufacturer's guidance.
