A step bit, available in 3mm and 4mm sizes, is a versatile drilling tool renowned for its efficiency in enlarging holes with precision. Featuring a unique stepped design, it allows users to drill multiple hole sizes using a single bit. The gradual increase in diameter creates smooth, burr-free holes in various materials like metal, plastic, and wood. Ideal for electrical and automotive applications, these bits are prized for their ability to create clean holes without the need for frequent bit changes. Their durable construction and sharp cutting edges ensure longevity and consistent performance, making them indispensable in workshops and DIY projects.
