Bosch Professional SDS-max-9 CoreCutter One-Piece Core Drill Bit SDS-max 68 mm x 290 mm

The Bosch Professional SDS-max-9 CoreCutter One-Piece Core Drill Bit is a one-piece core drill bit engineered for heavy-duty structural modification. It is designed to create deep openings for pipe penetrations and electrical switch box installations. The bit is rated for use on hard building materials, including solid brick, concrete, and standard masonry. Its integrated construction transfers drilling force directly from the rotary hammer to the cutting face, without the need for intermediate adapters. By eliminating multi-part assemblies, the cutter maintains high structural rigidity during demanding site work.

An SDS-max shank provides secure, tool-free compatibility with professional-grade rotary hammers. This connection standard handles the high rotational torque required for large-scale masonry drilling. The accessory uses the combined hammering and rotational action of the connected machine to break down dense surfaces steadily. Its fixed-shank profile prevents the bit from slipping or wobbling in the chuck under heavy operational load. The dedicated interface requires a matching SDS-max power source to ensure proper energy transfer and safe handling.

• 68 mm drilling diameter: sizes cavities correctly for standard electrical conduit and plumbing fixtures.
• 290 mm overall length: provides the reach needed for boring through thick external walls.
• 160 mm maximum working length: defines how deep the bit can travel into the substrate during continuous operation.
• 80 mm maximum cutting depth: limits the initial penetration into the material before the core must be cleared.
• 6 distinct cutting edges: distribute the abrasive workload to fracture hard concrete block efficiently.
