With the Bosch pro diamond core cutter, you can drill quickly and cleanly through masonry, limestone, and brick without the need for water cooling. This allows you to make precise 52 mm wall penetrations for pipes, drains, or cables in finished indoor spaces without water mess or slurry. Four robust diamond segments with a 7 mm segment height deliver consistent drilling speed and extended service life during heavy-duty applications. Thanks to the standard g 1/2" female thread and a 150 mm working length, this core cutter mounts securely and directly to compatible diamond core drills.
