Drill bit Smart SDS Plus Duo 8 x 600/550 mm

The Smart SDS Plus Duo 8 x 600/550 mm drill bit is designed for use with SDS Plus rotary hammer drills for drilling in masonry and concrete. With an 8 mm diameter and a 600 mm overall length (550 mm working length), this drill bit provides extended reach for through-holes, anchor installation and routing of conduits during construction and renovation tasks. The SDS Plus shank ensures compatibility with standard SDS Plus chisels and rotary hammers, while the bit geometry is optimized for efficient removal of drilling debris in deeper holes.

Advantages

This drill bit combines a long working length with a slim 8 mm diameter to enable deep drilling without changing to longer tooling. The SDS Plus connection offers secure retention and fast bit changes in compatible rotary hammers. The Duo design supports reliable performance in masonry and concrete and helps maintain hole straightness over the extended length. Material and flute design promote efficient dust evacuation to reduce friction and heat buildup during prolonged drilling.

Suitable for

• Installing anchors and fasteners in concrete and brick
• Drilling through-holes for cables, pipes and conduits
• Renovation work requiring deep penetration from one side
• Light to medium-duty construction tasks with SDS Plus rotary hammers

Key specifications

• Diameter: 8 mm
• Overall length: 600 mm
• Working length: 550 mm
• Shank type: SDS Plus
• Intended material: masonry and concrete

How to use

Fit the drill bit securely into the SDS Plus chuck of a compatible rotary hammer according to the tool manufacturer’s instructions. Select the rotary hammer’s drilling or rotary-percussion mode as appropriate for the substrate. Start drilling at low speed to seat the tip, then apply steady pressure and maintain a perpendicular angle to the surface. Periodically withdraw the bit to clear debris from the hole and allow cooling when drilling deep or for extended periods. Replace the bit if wear or damage affects drilling accuracy.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection and a dust mask when drilling masonry or concrete. When drilling long holes, consider using water suppression or a dust extraction system for cleaner work and improved bit life. Match drill speed and pressure to the material and machine capability to avoid excessive wear.
