How can I use this router bit?

I recently purchased a big 2 HP router and a 15 bit set from Harbor Freight. The router is going on the finished CNC router, but I also needed it to make a few chamfers on the sides of some of the parts. The router is one speed, and says that it has a "Maximum RPM of 29000". The chamfer bit that came with the set, on the other hand, says that it has a max speed of 18000. What do I do, now?

You can buy router speed controllers at many hardware and most woodworking supply stores. But a word of caution, there is no way I would ever consider using those big a$$ bits in a hand held router. One slip and serious damage can occur, to the wood piece or flesh.
Build a small router table and use that instead, its safer and does a better job.

I am definitely going to build a router table- the thing sounds like a jet engine. Are there any other ways to slow down the router (without a store-bought speed control)?
harbor Freight sells some cheap ones for around $20. I wouldn't want to take a chance on burning up an expensive router to save 20 bucks.

...eh, you're right. I think I'll just return this router and get a trim router with the harbor freight speed control.

if you want to slow the router down, i've often used (on other projects) an old sewing machine foot control. they work well because a sewing machine is also rather heavy duty and wont burn out.
You can build your own speed control out of a wall outlet or old power strip and a dimmer switch.

From what I've heard, most dimmers will practically explode when used with something as powerful as a router.
I've had no problem with a dimmer and a dremal.

A dremel 300 draws 1.15 amps. This router of mine draws 11. If only....

For those larger bits you need a variable speed router or you risk making some fun metal shrapnel to wreck your day.

That's where the problem comes in- for now, that big 2 HP router is all I have. I'll probably buy a speed controller for it in the future, but I need a temporary fix for it right now. Is there any way to slow down the router or make the cut with a different method?
use a smaller bit that can handle the rpm's...and if its cnc - program it to do more passes.

On a seperate note: Should I just return the router and get a trim router instead? I can purchase an actual speed controller with it, but I don't know if the trim router will be powerful enough to use the bigger bits in the set. This trim router, btw : http://www.harborfreight.com/power-tools/routers/1-4-quarter-inch-trim-router-44914.html

What you need to know is what its normal running speed is. The max is just that, it's self destruct beyond this point hi speed. But that speed is probably not the speed it usually operates at. That speed is probably much lower.
