I want to bore square holes. I would like to do so with a OF 2200. Is there an effective way to do so?
 
depends on the size of the holes, and the general application of it. more info would be helpful.

You either make a round hole by routing vertically down into the piece, and square off the edges with a chisel by hand.
Or you cut the piece in two, put the freshly cut side upward and route a dado in it, when you glue both halfs back together you have a square hole... If that makes sense, it's how i made the benchdog holes in my assembly table.
 
All of these responses are assuming that by square you mean "not round".

If you mean perpendicular to the surface of the wood, then you basically just need a router bit the size of the hole.

Just in case...

Thank you for your responses. I was wondering about using a hollow mortising chisel with the OF 2200 but I didn't want to forestall a wider conversation. However, now I seem to be at that point: would a hollow mortising chisel work on the OF 2200?

On the OF 2200 product page (http://www.festoolusa.com/products/routers/of-2200-eb-router-574277.html ) there is the heading "You might even think it is a portable shaper." I see the plunge capability and wish for it also to be a portable drill press with laser guides. I also wish for it to be a high precision driver: driving screws absolutely straight to an exact depth.
 
You could bore nearly-square holes using a simple jig and several router bits.

For example, let’s say you want a ¾” square-ish hole:
Create a jig with a ¾” square opening.
Using plunge router, with a ½” plunge/spiral bit and a 9/16” template collar, route out the majority of the material.
Change to a smaller bit and smaller collar.  Route out the majority of remaining material.  Alternative:  Use a jigsaw
Continue as needed until only a small amount remains with the final size of square.

Using a small diameter router bit (e.g. inlay bit, or very small diameter template bearing bit) you can whittle away the final mater, nearly to the corners of your square jig.

Your hole will not be square, but rather square shaped with slightly rounded corners.  Easy to square off manually via chisel or other tool.

Hmmmm....somehow I don't foresee a router that spins at 10,000-22,000rpm being a very effective screwdriver.  I think you may have issues with screws stripping out at those speeds.......
 
Curtis,

Hollow mortising chisels are not designed to operate at the speed of a router.
 
Curtis,
Peter is right, even if a hollow mortising chisel could somehow be fit on an OF2200, it is not designed to work at that speed.  Additionally, mortisers that use those chisels are very heavy and well secured to a structure to withstand torque.  I may have confused the issue with the link to the Lee Valley gadget, which uses the tip of a hollow mortise chisel, but the Lee Valley gadget is strictly a hand tool, to be used with a mallet.

Nor would the OF2200, or any router, be appropriate for driving screws, for one thing the braking time would be too long to accurately place the screw without spinning it around several hundred times at max depth, thereby ruining your thread.

Please be very careful when using a router, they can be very dangerous when pressed to do something they are not designed to do.

Wishing you happy and safe woodworking!!
 
even if you could fit a hollow chisel under it, you wouldn't be able to press it down, not even by sitting on it. Just try to press down your hollow chisel mortiser by pushing on the engine, it's impossible. Thats why they have levers and gears to multiply your force, and even then i sometimes need to hang my entire body weight on the lever to get strough tough hardwood.
