Drill bit DeWalt SDS+ 20 mm MDT-9598 for concrete

DeWalt SDS+ 20 mm drill bit MDT-9598 is engineered for drilling clean anchor and through holes in concrete and masonry. Designed for use with SDS+ rotary hammers, this 20 mm diameter bit provides the rigidity and geometry needed to penetrate dense materials while maintaining hole accuracy. The bit's construction suits both professional tradespeople and informed DIY users working on construction, renovation, or installation tasks that require reliable concrete drilling performance.

Advantages

The SDS+ 20 mm drill bit offers consistent drilling progress and reduced skipping during hammer action due to its tip geometry and balanced flute design. Compatibility with SDS+ chucks ensures quick and secure bit changes. The bit's robust build gives good wear resistance under repeated use in concrete and common masonry types, helping to maintain hole size and shape over extended jobs.

Suitable for

• Drilling anchor holes for fixings in concrete and brick
• Creating through holes for pipes, conduits and cable runs
• Construction and renovation tasks requiring precise concrete holes
• Professional and advanced DIY applications with SDS+ rotary hammers

Key specifications

• Shank type: SDS+ compatible
• Diameter: 20 mm
• Intended material: concrete and masonry
• Typical use: anchor and through holes
• Compatibility: designed for SDS+ rotary hammer chucks

How to use

Mark the drilling position and secure the work area. Install the MDT-9598 bit into an SDS+ rotary hammer chuck until it locks. Use the hammer drill on the appropriate mode for concrete, apply steady forward pressure, and allow the tool's impact action to advance the bit. Withdraw periodically to clear dust from the hole and maintain drilling efficiency. For through holes, confirm alignment from both faces as needed.

Usage recommendations

Use with appropriate personal protective equipment including eye protection, hearing protection, and dust mask. Select a suitable drilling speed and hammer setting for concrete, and avoid excessive lateral force to preserve bit life. For long or deep holes, remove debris regularly and consider using water extraction or dust-collection attachments where applicable.
