Text A

Video transcript from a video-taped demonstration in using a lathe to drill a hole in a metal workpiece

Now I have to change to the final size drill I require, which is three-quarters of an inch diameter, and this is called a morse-taper sleeve.

A slower speed for a larger drill.

Nice even feed should give a reasonable finish to the hole.

Applying coolant periodically. This is mainly for lubrication rather than cooling.

Almost to depth now.

Right. Withdrawing the drill.

That's fine.
