HSSCO5 CDS core drill in nACO, 14/18/22 mm, drilling depth 30 mm, 5 pieces

The tin- and nACO-coated CDS and CDL core drills are made of high-speed steel and designed for professional use. The sets include the most commonly used sizes and are available with a choice of drilling depths of 25 and 50 mm (tin coating) and 30 mm and 50 mm (nACO). An advantage of the core drill compared to twist drills is that the entire drilling surface is not machined, but only a thin ring. This way, the effort is much lower
