The Irwin Step Drill Bits are designed for precise drilling in thin materials and have a single flute for maximum drilling control into sheet metal. Their unique flute design ensures perfect round holes in sheet metal. A fluted shank also prevents the drill bit from slipping in the chuck, along with a self centring point that will not walk and eliminates centre punching.

Made from industrial grade M7 high-speed steel.
