Rotary Hammer Drill Bit Bosch Expert SDS Clean plus-8X 14 mm x 400 mm

Bosch Expert SDS Clean plus-8X 14 mm x 400 mm is a rotary hammer drill bit designed for drilling deep, precise holes in masonry and concrete with SDS-compatible rotary hammers. The 14 mm diameter and 400 mm overall length make it suitable for applications that require extended reach or deeper anchor and dowel placement. The bit is built with the Expert line construction to ensure stable performance and compatibility with SDS chucks, offering controlled drilling and reduced bit wandering during use.

Advantages

The drill bit provides stable drilling performance and is optimized for clean material removal to reduce dust buildup inside the hole. Its geometry and construction are intended to deliver reliable centering and consistent penetration in hard materials. Compatibility with SDS-style chucks ensures quick, tool-free bit changes and secure retention during hammer drilling. The extended length allows deeper drill depths without the need for extensions.

Suitable for

• Drilling deep anchor or dowel holes in concrete and masonry
• Through-holes for rebar positioning and service lines in walls
• Installation tasks requiring extended reach into structures
• Professional trade and advanced DIY drilling where SDS rotary hammers are used

Key specifications

• Diameter: 14 mm
• Overall length: 400 mm
• Shank type: SDS-compatible
• Intended materials: concrete, masonry
• Design focus: deep-hole drilling and clean material evacuation

How to use

Select a rotary hammer with an SDS-compatible chuck and set the tool to hammer-drill mode when working in concrete or masonry. Mark the drilling point, secure the work area, and start drilling at low speed to establish a center. Apply steady, moderate pressure without forcing the bit; let the tool's hammer action advance the drill. Periodically withdraw the bit to clear debris and ensure consistent dust removal, especially when drilling deep holes. Replace the bit if wear degrades cutting performance.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, and a dust mask or extraction system when drilling. For best results in reinforced concrete, inspect holes for debris and consider using a vacuum or blow-out step between passes. Match the bit length to the required embedment depth to avoid excessive bending or stress on the bit.
