What is drill sleeve?

A drill sleeve is a cylindrical tool used in machining to adapt drill bits or tools to fit different spindle sizes or to extend the reach of a drill. It allows for greater versatility in drilling operations by providing a means to hold smaller tools in larger machines. Drill sleeves are typically made from durable materials to withstand the stresses of drilling and can be found in various sizes to accommodate different tool shanks. They are essential in ensuring precision and stability during the drilling process.
