Bosch SDS max-9 Core Cutter 55 x 420 mm

The Bosch SDS max-9 Core Cutter 55 x 420 mm is a single-piece drilling accessory engineered for creating cylindrical holes in mineral building materials. It is designed for core drilling in concrete, masonry, and limestone. Its primary function is to remove large solid cores, making it practical for routing utility cables or installing conduits through structural walls. The cutter is driven by an external power source and must be paired with a compatible hammer drill. By relying on rotary hammer action, the accessory transfers impact energy directly to the working surface, maintaining controlled material removal even in dense substrates.

Connecting the cutter to a power tool requires a chuck that supports the SDS-max system. This mounting standard ensures a secure connection capable of withstanding high torsional loads during core extraction. The geometry of the cutter bit keeps the hole clean and cylindrical as it advances through tough building materials. Because it is built as a single unified accessory, no separate arbors or extension rods are required. The long profile provides substantial reach, allowing operators to bore through thick masonry walls from one side. A single core cutter is included in the package, ready to be added to an existing tool kit.

• 55 mm drill bit diameter creates consistently sized channels for conduit and pipe installations.
• 420 mm working length permits deep drilling without the need to stop and reposition the tool.
• 550 mm overall length provides extended reach for penetrating thick walls in a single setup.
• 80 mm maximum cutting depth defines the largest material core that can be extracted in one continuous pass.
• 6 integrated cutting edges maintain stability and preserve the cylindrical shape of the hole during operation.
• SDS-max shank shape ensures direct compatibility with large rotary hammer drills without requiring adapters.
