Drilling small holes in hard materials is best done with a crown drill. With a crown drill, you can easily drill holes between Ø8 and Ø40 mm in (reinforced) concrete and stone. Ideal when you need to drill holes for installing a pipe, ventilation duct or electrical wires.

Crown drill for concrete

A crown drill is a diamond drill bit made from a thin drill tube. The segment and the diamond grains of the drill bit determine for which material the crown drill is most suitable. Because the tube of our crown drills is only 2 mm wide, you can quickly drill in (reinforced) concrete and concrete tiles. A crown drill is the ideal tool for making a water pipe duct for example.

Crown drill for stone

With Adamas crown drills you can also easily drill holes in all types of stone, including sand-lime brick, brick and natural stone (such as marble and granite). Helpful when you want to install pipes or cables.
