The spiral flute will make drilling smoother, and the drill bit offers a balanced ratio between multi-purpose use and diameter flexibility, which makes sense where there is no need for highly specialized drill bits for hard materials such as concrete. For exclusive use on very hard materials such as stone, the drill bit is not the optimal choice. A welcome feature is the wide diameter range, which allows for multiple solutions with one drill bit.\u003c\/p\u003e\u003cp\u003e \u003cem\u003eRecommendation source: Enaa guides and team experiences.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003e User view\u003c\/h2\u003e\u003cp\u003e The Bosch step drill bit is most often used by DIYers, craftsmen and those who need flexibility when drilling different diameters in metal, e.g. for assembly, repairs, expanding openings or making holes for electrical wiring.
