Drill bit Bosch SDS-max-8X 12 mm for reinforced concrete, length 740 mm

Long SDS-max-8X drill bit by Bosch with a 12 mm diameter and 740 mm overall length, engineered for drilling reinforced concrete. This drill bit is designed for use with SDS-max rotary hammers and provides extended reach for deep holes while maintaining stability during heavy-duty drilling tasks. The geometry and material selection focus on wear resistance and efficient dust removal to support continuous operation on construction sites and renovation projects.

Advantages

The Bosch SDS-max-8X 12 mm drill bit combines an extended length with a robust tip design that improves penetration in reinforced concrete. Its construction reduces breakage risk when drilling through aggregate and steel reinforcement, and the flute profile promotes effective debris evacuation to keep the bore clear. Compatibility with SDS-max chucks ensures secure mounting and reliable transfer of hammering force for consistent performance under load.

Suitable for

• Drilling deep anchor holes in reinforced concrete
• Construction and structural installation work requiring extended reach
• Demolition and renovation tasks where long-reach drilling is needed
• Professional trade applications using SDS-max rotary hammers

Key specifications

• Shank type: SDS-max
• Diameter: 12 mm
• Overall length: 740 mm
• Material application: reinforced concrete
• Intended use: rotary hammer drilling with hammer function

How to use

Fit the SDS-max shank securely into the rotary hammer chuck according to the tool manufacturer’s instructions. Mark the drilling point and start at low speed to establish the hole, then apply steady forward pressure while using the hammering mode to progress through reinforced concrete. Withdraw the bit periodically to clear accumulated dust and debris from the hole and the flute. Use appropriate coolant or air extraction if available to reduce dust and prolong bit life.

Usage recommendations

Use personal protective equipment including eye and hearing protection and a dust mask when drilling reinforced concrete. Match the drill bit diameter to the anchor or insert specified for the installation. For best results, pair the bit with a suitable SDS-max rotary hammer rated for heavy-duty concrete work and follow manufacturer guidance for hammer force and speed settings.
