Bosch SDS-max-8X drill bit for concrete and reinforced concrete, SDS-max shank, 12 mm diameter, 540 mm length

Bosch SDS-max-8X drill bit for concrete and reinforced concrete is a long SDS-max shank bit with a 12 mm cutting diameter and a total length of 540 mm, intended for use with compatible SDS-max rotary hammers. Engineered for hammer drilling in masonry, concrete and reinforced concrete, this bit enables drilling of deep holes for anchors, rebar clearance and structural fastening. The SDS-max connection provides a secure fit and efficient impact transfer from the tool to the carbide tip for sustained performance in heavy-duty applications.

Advantages

The SDS-max shank ensures fast, secure coupling and reliable torque transfer with SDS-max rotary hammers. A carbide-tipped cutting head and robust flute geometry deliver consistent drilling speed and long tool life when penetrating concrete and reinforced concrete. The extended 540 mm length allows drilling deep holes without extensions, reducing the need to change bits during anchor and through-drilling tasks. The 12 mm diameter is suitable for common anchor sizes and creates accurate, straight holes when used with stable tool handling.

Suitable for

• Drilling anchor holes in concrete and masonry
• Through-drilling for pipes and conduits
• Creating clearance holes around rebar in reinforced concrete
• Structural fastening and installation of heavy fixtures

Key specifications

• Shank type: SDS-max compatible
• Cutting diameter: 12 mm
• Total length: 540 mm
• Intended material: concrete and reinforced concrete
• Tip: carbide cutting head for hammer drilling

How to use

Mount the drill bit into an SDS-max rotary hammer according to the tool manufacturer's instructions until it locks securely. Select the hammer drilling mode for concrete. Position the bit at the desired drilling point, start the tool at low speed to establish the pilot hole, then apply steady pressure while maintaining tool alignment to avoid bit bending. Periodically withdraw the bit to remove dust and debris from the hole for optimal drilling efficiency and to prevent overheating. Use appropriate personal protective equipment including eye and ear protection and respiratory protection suitable for masonry dust.

Usage recommendations

For best results, pair the 12 mm x 540 mm SDS-max-8X drill bit with an SDS-max rotary hammer of adequate power for deep drilling tasks. Keep the bit clean of debris and avoid side loads to extend service life. When drilling through heavily reinforced concrete, drill at moderate speed and clear debris frequently to maintain cutting performance.
