Step Drill Bit 4-12

This is a step drill bit (often called a pagoda bit), a versatile tool designed to drill various hole diameters in thin materials like sheet metal, plastic, and wood without changing bits. It features a conical shape with multiple graduated "steps" that allow you to enlarge a hole incrementally, while the spiral flute design ensures smoother cutting and efficient debris removal. This specific model includes a 1/4-inch hex shank for quick-change compatibility with impact drivers and is typically made from Cobalt High-Speed Steel (M35) to provide the heat resistance needed for drilling through tougher metals like stainless steel.
