A step drill bit, also known as a unibit, is a versatile cutting tool used to create stepped holes in various materials such as metal, plastic, and wood. It features a conical shape with multiple cutting edges of increasing diameters, allowing for precise hole enlargement in a single operation.
Step drill bits offer numerous advantages. They eliminate the need for multiple drill bits of different sizes, saving time and effort. Their stepped design ensures clean and accurate holes, reducing the risk of material damage. Additionally, step drill bits are durable and long-lasting, making them a cost-effective solution for various applications.
