Drill Bit Smart365 SDS Plus Duo 14 x 450/400 mm

The Smart365 SDS Plus Duo 14 x 450/400 mm drill bit is engineered for SDS Plus rotary hammers to create through-drilled and deep holes in concrete, masonry and similar mineral materials. Its duo design and extended length provide a combination of penetration efficiency and stability for jobs that require reaching greater depths or drilling fully through structural elements. The bit is compatible with standard SDS Plus chucks and is intended for construction, renovation and installation tasks where reliable drilling performance and longer reach are necessary.

Advantages

This SDS Plus duo drill bit delivers stable drilling in reinforced concrete and masonry thanks to its optimized flute geometry and robust carbide tip. The extended 450/400 mm length reduces the need for extensions or multiple operations when working on deep holes. The SDS Plus shank ensures secure retention in compatible rotary hammers, providing consistent impact transfer and reduced slippage during use.

Suitable for

• Drilling through concrete walls and floors
• Installation of anchors, through-bolts and sleeves
• Making deep service channels for pipes and conduits
• Renovation work requiring long-reach drilling

Key specifications

• Shank type: SDS Plus compatible
• Tip material: tungsten carbide tip for concrete and masonry
• Design: duo/fluted design for efficient dust evacuation and stable drilling
• Usable length: 400 mm (effective drilling depth)
• Total length: 450 mm
• Diameter: 14 mm

How to use

Fit the drill bit into a rotary hammer with an SDS Plus chuck, ensuring it clicks into place. Select the hammer or rotary mode appropriate for concrete or masonry and set speed/power according to the tool manufacturer’s guidance. Begin drilling at moderate pressure to establish the hole, then apply steady forward force while allowing the tool to do the work. Withdraw periodically to clear dust if drilling deep holes and to avoid overheating the bit. After finishing, retract the bit fully and inspect the hole for required dimensions.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For best results in reinforced concrete, use intermittent drilling and avoid excessive lateral force. Match the drill mode and power to the material hardness and consult the rotary hammer’s manual for recommended bit diameters and operating parameters.
