Yes there are a lot of companys that make Right Angle Heads to mount in a VMC to do side holes. I have used Pibomulti heads. They are very good heads. I work with them in the US but they are based out of Switzerland. Here is there website.

I also know that Lyndex makes some RAH’s as well. Just google “right angle heads” you will have a bunch to choose from.
