A Morse taper is a type of conical fitting used to securely hold tools in place, primarily in machine tools like lathes and drill presses. It features a tapered design that allows for a tight fit when the tool is inserted into the spindle. The taper is named after its inventor, Stephen Morse, who developed this system in the 19th century. Morse tapers come in various sizes, designated by numbers, with larger numbers indicating smaller tapers. This system allows for easy tool changes and ensures that tools remain stable during operation. Common applications include holding drill bits and milling cutters, enhancing precision in machining tasks.
