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 and a self centering point that will not walk and eliminates centre punching.
Made from industrial grade M7 high-speed steel.
