Core cutter Bosch SDS max-9, single piece, for drill, weight 99.8 g

Bosch SDS max-9 Core cutter, single piece, is a one-piece hole saw designed for use with SDS max-compatible drills. Weighing 99.8 g, this single core cutter is intended for creating precise round openings in concrete, masonry and limestone for tasks such as installing switch boxes. The tool features a fine-grade, highly durable carbide cutting edge and an asymmetric tooth layout sized to the cutter diameter to balance aggressive material removal with reduced vibration. A long 2-flute U-shaped shank supports efficient dust evacuation and reliable breakthrough drilling while ensuring secure power transfer from the machine to the cutter.

Advantages

The one-piece design provides optimum transfer of the drill’s power and reduces the risk of loosening during operation. Fine-grade carbide teeth offer improved wear resistance for extended service life in abrasive substrates. The asymmetric tooth arrangement and appropriate tooth count for the diameter deliver steady cutting progress and quieter operation compared with uniformly toothed cutters. The U-shaped, 2-flute shank facilitates dust removal and helps maintain drilling performance during deep cuts.

Suitable for (tasks / use cases)

• Cutting round openings for electrical switch boxes and conduit entry
• Drilling through concrete, masonry and limestone
• Light-duty core cutting where SDS max connection is required
• Situations requiring quieter operation and reduced vibration during hole cutting

How to use

Fit the Bosch SDS max-9 Core cutter into an SDS max-compatible drill according to the drill manufacturer’s instructions, ensuring the shank is fully seated and locked. Mark the center of the intended opening and start drilling at low speed to establish the pilot position, then increase speed and apply steady, even pressure. Allow the cutter to advance under its own cutting action and withdraw periodically to clear dust from the hole. For breakthrough drilling, reduce feed pressure as the cutter nears the far face to avoid chipping. After completion, remove the cutter following the drill’s removal procedure and clear any remaining material from the hole.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and a dust mask. Select recommended drilling speed and feed rate for the base material and avoid excessive side loads. For continuous work, allow the cutter to cool and clear debris frequently to prolong tool life. The tool is intended for light-duty core cutting tasks; for heavier industrial core drilling consider cutters designed for multi-piece systems or larger diameter, reinforced designs.
