The Faithfull 3 Piece HSS Step Drill Bit Set provides a versatile solution for drilling multiple hole sizes in thin sheet materials without the need to change bits. Ideal for electricians, plumbers and HVAC engineers working with metal panels, electrical enclosures and ducting, these step drills cut clean, parallel holes in material up to 4mm thick.
