Hi.. I just got a drill press and the manual shows how to use the
spindle lock, inserting a bolt into a threaded hole, but what is it
supposed to lock and when are you suppose to use this?

Also is it a common practice to use a mallet to install the chuck, I
wasn't sure how far the chuck should go into the tapered arbor, but I
was afraid the hammering might increase the runout of the drill.
Nothing is slipping so seems to be working for now.


The splindle lock holds the spindle in place after it hase been
extended by some arbitrary length. Not trying to sound smart, but when
you need it you'll know! It's a very useful feature that is often
not present on todays cheaper drill presses. Sounds as if the one
you describe works like a set screw. The more traditional (and IMHO
better) way is to have a split in the housing around the spindle and
a clamp bolt arrangement that tightens the housing up around the
spindle. I've seen set-screw style used to retrofit a drill press
that did not have a factory spindle lock and it's certainly better
than nothing.

Don'w worry about the mallet, that is the correct way to install
the chuck. Just make sure the tapered surfaces inside and outside
are clean and dry. One or 2 good whacks are usually all that is necessary
