With the Carat Brilliant HTS0766040, you drill clean and precise cutouts for standard electrical back boxes in brick and abrasive masonry. Working completely dry without water cooling prevents indoor water mess during electrical renovations and new construction projects. The specialized twisted diamond segments deliver immediate grip for a smooth, controlled start, while the laser welded design ensures lasting resilience during demanding drilling tasks. Featuring an M16 internal female thread, this 76 mm core bit with a 60 mm usable depth mounts easily onto a spindle or Dustec chuck for low-dust drilling in rotary mode.
