Jacobs taper is a type of taper used in the design of drill bits and other tools. It features a conical shape that allows for easy attachment to a drill chuck, ensuring a secure fit. This design helps to prevent slippage during operation, making it a popular choice in various machining applications. The taper is named after William Jacobs, who developed this standard in the early 20th century. Jacobs tapers are commonly found in lathe and drilling machines, providing versatility and efficiency in tool changes. They come in different sizes, allowing for compatibility with various equipment.
