Drill bit Dedra SDS MAX 20 mm WXQ2057 for concrete

The Dedra SDS MAX 20 mm WXQ2057 drill bit is a masonry drilling tool designed for use with SDS MAX rotary hammers. Engineered for concrete and other common masonry materials, this 20 mm diameter bit provides a balance between hole size and drilling speed for medium-duty construction tasks such as anchor installation, through-holes and general drilling in reinforced or non-reinforced concrete.

Advantages

This SDS MAX masonry bit features a robust shank connection for secure seating in compatible rotary hammers and improved power transfer during hammer drilling. Its 20 mm diameter is a common size for mechanical anchors and through-holes, offering reliable hole geometry and stable drilling performance. The bit is intended for repeated use in construction environments and combines practical durability with straightforward compatibility with SDS MAX systems.

Suitable for

• Drilling anchor holes in concrete and masonry
• Creating through-holes for pipes and conduits
• General medium-duty holemaking in reinforced and non-reinforced concrete
• Work with SDS MAX rotary hammers on construction sites and renovation projects

Key specifications

• Drill type: SDS MAX masonry bit
• Nominal diameter: 20 mm
• Primary materials for use: concrete and common masonry
• Intended tool interface: SDS MAX shank
• Typical applications: anchor installation, through-holes, general construction drilling

How to use

Install the bit into the rotary hammer’s SDS MAX chuck until it locks in place. Select the hammer-drilling mode on the tool and position the bit at the marked drilling location. Apply steady axial pressure and allow the hammer action to perform the cutting; avoid excessive force that can overload the bit or the tool. For deeper holes, periodically withdraw the bit to remove dust and debris and to cool the cutting edges. After use, retract the bit and inspect it for wear before storage.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and follow the rotary hammer manufacturer’s instructions. Match the 20 mm diameter to suitable anchors and accessories and ensure the rotary hammer is rated for SDS MAX bits and the drilling depth required.
