Hammer drill bit Bosch Expert SDS Clean plus-8X 16 mm diameter, working length 400 mm

The Bosch Expert SDS Clean plus-8X 16 mm diameter, 400 mm working length hammer drill bit is designed for rotary hammer drills with an SDS shank system. It is intended for drilling through concrete and masonry where extended reach is required for anchors, through-holes or deep fixing points. The bit geometry and material selection are aimed at sustaining impact load and delivering consistent drilling progress in dense building materials.

Advantages

The drill bit combines a 16 mm cutting diameter with a 400 mm effective length to enable deeper holes without the need for extension accessories. Its SDS-compatible shank allows quick and secure tool engagement and efficient transfer of percussive energy. The tip and flute design reduce dust buildup during drilling and support stable chip removal, which helps maintain drilling speed and accuracy on concrete and masonry substrates.

Suitable for

• Drilling anchor holes in reinforced and plain concrete
• Installing through-fixings and sleeves in masonry
• Renovation work requiring deep or continuous holes
• Professional construction tasks with SDS hammer drills

Key specifications

• Shank type: SDS (suitable for SDS hammer drills)
• Diameter: 16 mm cutting diameter
• Working length: 400 mm effective drilling length
• Intended material: concrete and masonry
• Function: percussive rotary drilling for anchors and through-holes

How to use

Select an SDS-compatible rotary hammer and secure the bit in the chuck according to the tool manufacturer's instructions. Mark the drilling position and start drilling at low speed to create a guide indentation, then increase speed and apply steady axial pressure appropriate to the tool and material. Withdraw the bit periodically when drilling deep holes to clear dust from the hole and maintain efficient cutting. Use personal protective equipment including safety glasses, hearing protection and dust mask when drilling concrete.

Usage recommendations

For optimal performance, use the bit in hammer drilling mode on SDS rotary hammers rated for concrete work. Avoid side loading and bending forces; when drilling through reinforced areas, proceed with controlled pressure and accept slower advance to prevent damage. For consistent hole diameter and clean anchoring, clear dust from the hole before inserting anchors or sleeves.
