HSS step drill set, CBN ground, with spiral grooves The deep-ground, spiral cutting groove offers absolutely smooth running and high cutting performance. In particular, swarf which does not break off is carried away cleanly, as with a spiral drill. This reduces the formation of cutting build-up and cold welding on the cutting edges. The cone makes pulling back easier from metal sheets that have been drilled through. for metal sheet up to 2.0mm 413276 Price Each Mftrs. List No. A101038 Order Code 970-0846
