Drill bit DeWalt SDS-Plus Extreme2 10 x 600/550 mm

DeWalt SDS-Plus Extreme2 10 x 600/550 mm is a rotary hammer drill bit engineered for heavy-duty drilling in concrete, masonry and natural stone. The 10 mm diameter and 550 mm working length allow access to deep anchor and through-hole applications while the SDS-Plus shank ensures secure fit and efficient power transfer in compatible rotary hammers. Reinforced tip geometry and a flute profile designed for effective dust and debris evacuation help maintain drilling speed and reduce wear during repeated hammer drilling.

Advantages

This drill bit combines a hardened tip design with an optimised flute to improve chip removal and extend bit life under percussion loads. The SDS-Plus connection enables quick bit changes and reliable retention in rotary hammers. The long overall length provides extended reach for recessed or deep holes without compromising rigidity, and the durable construction is intended to resist the stresses of demolition and professional drilling tasks.

Suitable for

• Drilling holes for anchors and through-holes in concrete and reinforced concrete
• Installing dowels, bolts and rebar connections in masonry
• Core drilling and deep-hole applications where extended reach is required
• General demolition and renovation tasks involving masonry and stone

Key specifications

• Diameter: 10 mm
• Total length: 600 mm
• Working length: 550 mm
• Shank type: SDS-Plus
• Tip geometry: reinforced for percussion drilling
• Flute design: optimised for fast debris removal
• Primary materials: hardened steel construction designed for impact drilling

How to use

Insert the SDS-Plus shank into the rotary hammer’s chuck until it locks, ensuring the tool is switched off before changing bits. Select appropriate drill speed and hammer settings for concrete or masonry and start drilling with steady axial pressure; avoid excessive lateral forces that can damage the tip. Periodically withdraw the bit while drilling deep holes to clear accumulated dust and allow the flute to evacuate debris. Use personal protective equipment including eye protection, hearing protection and a dust mask when drilling.

Usage recommendations

For best results in reinforced concrete, use a rotary hammer with sufficient impact energy and match drilling speed to material hardness. Replace the bit if the tip shows excessive wear or if drilling becomes slower despite correct technique; continuing to use a worn bit can lead to poor hole quality and increased stress on the tool. Keep flutes clean and store the bit in a dry place to prevent corrosion.
