The mandrel assembly provides a quick-connect/quick-release connection between the tool output shaft and the accessory via a clamping action. In particular, the mandrel assembly is operable to clamp the accessory between elastic clamping jaws that protrude from one end of the mandrel and a collar which surrounds the mandrel and is spring-biased toward the mandrel end.","english":"A mandrel assembly may be used with a rotary power tool to provide a reliable and stable connection between the rotary tool and a tool accessory.
