For lathe work my dad always taught me to drill an undersize hole, followed by a single point boring tool, then finally the machine reamer.

If you miss out the boring tool stage, there is every chance your original drilled hole could have wandered off centre, the reamer will then just follow it with the same error. The single point boring tool will correct any hole wander prior to reaming.

That was excellent advice especially where the exact hole position needs to be maintained.

Thanks Graham, & Phil P. I can see the boring tool followed by the reamer covering all the bases, off to look see what a single point one looks like!
