What tool is essential for separating a drill from a drill sleeve?

Explanation:
Separating a drill from its sleeve is done with a drill drift because this tool is made to fit the gap between the drill and the sleeve and apply a controlled wedge force to break the taper’s grip. By inserting the drift and giving a light tap, you push the drill straight out without hammering the surfaces or risking distortion. This protects the mating faces and keeps alignment intact. Using a hammer alone can mar the surfaces, a pry bar can pry too hard or cause damage, and a punch isn’t shaped for prying the two tapered parts apart. The drill drift is designed for this exact task, which is why it’s the essential tool.
