RUKO  A101038  阶梯钻套件, HSS, CBN打磨

The is a Step Drill Set made of high speed steel HSS offers CBN ground. 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.
