Core cutter drill bit Bosch SDS max-9 — diameter 82 mm, compatible with SDS max

The Bosch SDS max-9 Core cutter drill bit with an 82 mm cutting diameter is designed for creating circular openings in concrete, masonry and similar materials. Built for rotary hammers that accept SDS max tooling, the bit features a one-piece design and a long 2-flute U-shaped shank for efficient dust extraction and reliable power transfer. Carbide-tipped, asymmetric teeth are matched to the diameter to provide aggressive cutting progress with reduced vibration and quieter operation. The tool is suitable for professional installation tasks such as plumbing, electrical and construction openings where precise, deep core holes are required.

Advantages

The single-piece construction ensures direct transfer of impact and rotational energy from the machine to the cutting edge, improving drilling efficiency and durability. Fine-grade, highly durable carbide teeth provide improved wear resistance for prolonged service life in abrasive materials. The asymmetric tooth arrangement is optimized for the 82 mm diameter to deliver fast material removal while maintaining stable, quieter performance. The 2-flute U-shaped shank improves chip and dust evacuation during deep drilling and breakthrough operations, reducing clogging and helping maintain cutting performance.

Suitable for

• Making circular openings for switch boxes and wall-mounted fittings in concrete and masonry
• Creating holes for plumbing and electrical installations
• Drilling through limestone, brick and similar building materials
• Professional construction and renovation work requiring SDS max tooling

Key specifications

• Cutting diameter: 82 mm
• Shank type: SDS max compatible, long 2-flute U-shaped shank
• Tip material: fine-grade carbide teeth
• Design: one-piece construction for direct power transfer
• Recommended materials: concrete, masonry, limestone

How to use

Mount the core cutter securely into the SDS max chuck of a suitably rated rotary hammer. Position the bit on the marked point and apply steady axial pressure while operating the rotary hammer at the recommended speed and impact settings for the base material. Allow the carbide teeth to cut progressively and withdraw periodically if necessary to clear dust. For breakthrough drilling, reduce pressure near the end of the hole to avoid sudden jumps. After use, clean the shank and teeth from dust and debris before storage.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection and a dust mask. Choose an SDS max rotary hammer with sufficient impact energy for 82 mm holes in concrete. For prolonged life of the carbide teeth, avoid excessive side-loads and keep the bit free from packed dust; consider using dust extraction or periodic clearing while drilling.
