Diamant-Kernbohrer 107 mm x 150 mm + Sechskantdorn 100 mm + Pilotbohrer

Full 150mm cutting depth spans the cavity to ensure that holes in the inner and outer leaves of the cavity wall line up. In most instances this allows the complete hole to be drilled from one side. A diamond cutter will also cut a cleaner hole than tungsten tipped cutters.
