In a nutshell
The right choise for
Drill clean and accurate recesses for flush-mount boxes in brick and abrasive masonry with the Carat HDNS102062 diamond core drill. Featuring turbo-twisted diamond segments, this bit bites immediately into the surface for smooth, precise starts without chipping or damaging surrounding brickwork. The robust laser-welded segments deliver maximum resistance against detachment during demanding dry drilling. With a 102 mm diameter and a 60 mm working depth, it creates neat round holes in a single pass. The standard 5/4" unc connection pairs with compatible core drilling machines to extract dust directly through the spindle for a cleaner, more productive workspace.
