When trying to separate a drill and a drill sleeve, it is important that a drill drift be used.

• A. that a drill drift be used
• B. that a hammer be used
• C. that a punch be used
• D. that a wrench be used

Answer: (A)

When separating a drill from its sleeve, you want an axial, controlled push to eject the drill without harming the parts. A drill drift is designed for this purpose: it fits into the end of the drill shank or into a groove so you can drive the drill straight out with a tap of the hammer. This direct, centered force minimizes bending, galling, or scratching of the sleeve and drill, and it helps keep the alignment correct as the drill frees from the sleeve.

Using a hammer directly on the drill or sleeve can gouge or deform surfaces, and a punch can mar the outer features or damage the sleeve. A wrench has no role in pushing the drill out. So, the drill drift is the appropriate tool because it provides the proper fit and aligned thrust needed to remove the drill safely and cleanly.
