Product description
Step spiral drill bit adapted for drilling in various types of steel, non-ferrous metals, plastics and wood. It enables drilling precise holes. The drill bit has spiral cutting grooves, which are one of the most effective technologies used in step drill bits and which enable much quicker and more effective drilling of holes, the edges of which remain precisely deburred. It can be used in tinsmith services, car workshops or in installers and electricians work. For professional use.
