Bosch Diamond Core Cutter for Wet Drilling 132 x 450 mm, 1 1/4" UNC

The Bosch PRO Core Cutter Wet Diamond Core Cutter is a single-piece diamond wet drilling crown intended for structural masonry applications. It is designed to produce precise openings for anchors, plumbing pipes, and similar permanent installations. The cutting profile is engineered to penetrate concrete and reinforced concrete without damaging the surrounding material. Rather than grinding away all the masonry within the target area, the crown removes an intact solid cylinder. This core-cutting method delivers a consistently controlled internal diameter across the full depth of the bore. On site, tradespeople rely on this format to maintain exact dimensional accuracy.

The cutting edge is built from industrial diamond grit bonded into a durable metal matrix. This segment design keeps the abrasive teeth firmly in place under heavy continuous loads. Consistent performance also depends on pairing the attachment with a drill rated for wet operation. The required water flow cools the bonded cutting segments throughout the boring process, and introducing fluid directly to the cut substantially reduces the volume of airborne concrete dust. Together, these factors allow the tool to maintain stable progress through dense material.

• 132 mm working diameter — defines the exact size of the resulting opening for large pipe installations.
• 450 mm working length — sets the maximum penetration depth before the concrete core must be snapped off and removed.
• 1 1/4" UNC threaded shank — provides direct compatibility with standard professional core drilling motors.
• Laser-welded segment construction — delivers high structural stability, securing the cutting teeth against extreme torsional shear forces.
• 4,660 g overall weight — reflects the heavy-duty steel barrel required to maintain full rigidity during deep cuts.
