Diamond Core Drill Bit

The kwb diamond hollow core bit is a specialised tool for precise drilling in hard materials such as masonry, natural and artificial stone, tiles and bricks. With an external diameter of 68 / 82 mm and a total length of 89 mm and an internal depth of 60 mm, it provides deep and clean cuts. Its three laser-welded DIA segments guarantee a long service life and precise drilling results. The M16 internal thread allows universal application with all suitable receptacle shanks. The black lacquered, lightly oiled surface protects the core drill against corrosion and ensures a long service life.
