Bosch Professional Diamond Core Cutter for Wet Drilling 122 x 450 mm, 1 1/4" UNC

This 1-piece Bosch PRO Core Cutter Wet is a specialised drilling crown designed to produce 122 mm diameter cavities. The accessory is engineered for wet core applications across demanding construction sites. It is rated for continuous work in dense mineral structures, providing a reliable solution for structural penetrations. Operators use this specific size class to route plumbing, pass service lines, or prepare heavy-duty anchor points. Instead of grinding away the entire hole volume, the tool cuts only the outer perimeter, extracting a solid cylinder of material. This targeted approach reduces the overall energy required to complete wide bores. The resulting cavities have clean, accurately sized edges that need little post-drilling preparation.

Operating this attachment requires pairing it with a compatible external diamond core drilling machine. The crown functions strictly as an accessory and relies entirely on the connected rig for rotational force and fluid delivery. Introducing a constant water flow during use is essential to cool the cutting surfaces and suppress hazardous masonry dust. Proper fluid dynamics also flush grinding slurry away from the working zone, preventing the unit from binding deep inside the material. Because the core cutter handles extreme friction, the rig must supply steady torque to maintain a consistent advance rate. Active fluid management protects the structural integrity of the surrounding masonry. These operational traits keep the attachment stable when navigating through dense structural barriers.

• Diamond grit suspended in a metal matrix provides high abrasion resistance for demanding drilling tasks.
• 450 mm maximum working length allows deep, continuous penetrations through thick walls and flooring.
• 1 1/4" UNC shank configuration ensures direct mounting onto standard professional drill rigs without adapters.
• 3300 g overall weight reflects the solid-metal construction necessary to withstand high operational forces.
• Rated specifically for safe, continuous applications involving standard concrete and steel-reinforced concrete structures.
