IRWIN Tools 10502ZR Unibit Sheet Metal Step Drill Bit Set is a selection of the most popular Unibit step drill bits in the low diameter range (below 7/8"). Ideal for drilling true round holes with precise control in a variety of materials like sheet metal, metal plates, aluminum, fiberglass, plastics, plexiglass, and wood. The specially designed cutting edge drills true, round holes for a smooth, clean finish, and the SpeedPoint tip penetrates fast, prevents "walking," and eliminates the need for a pilot/starting hole. The hex shank provdes a secure grip in the drill chuck. Plus, the permanent laser-etched sizes inside the flute are easy to read for precise control during the hole enlarging process. Contains: Unibit #1 with 13 hole sizes (1/8" to 1/2" by 32nds), Unibit #2 with 6 hole sizes (3/16" to 1/2" by 16ths for deeper steps), and Unibit #3 with 9 hole sizes (1/4" to 3/4" by 16ths). Product made in USA.
