I don't have one but lots of members have. You can't use them is you already have one built in. If you get one make sure the amp rating is equal to or greater than what you intend to plug into it.
I go by the sound of the bit. I turn on the router with no load on the bit and dial it up til it sounds nice and smooth,no vibration, not screaming. The small diam. bits, will take the full speed, the larger bits will take a slower speed.As a second-round newbie (I've been substantially away from routers for several decades) I have a question about speed controls. It seems basic, but ...
I know that a fair number of router bits specify a maximum speed. So the question is, with an add-on router speed control,
How does one know what the current speed is?
I know there are several ways I could measure it in static, no-load conditions. (Build a simple optical or Hall-effect tachometer.) But what about real world in-use conditions?

I am the same never used speed control because I don't have any bit over 38mm (1 1/2"). The vast majority of my routing is done with bits less than 20mm diameter.I've had a 1/2" makita router in my table for 4 years now. No speed control. never needed one so far. I've used bits up to 1 1/2" across with no problems.
I suspect 2" wide or more would definitely need speed control.
I have the same unit and never been game to use it with my 1600 watt router, it says its up to 2000 watts, but I suspect it would get very hot with anything over 1000 watts. Does yours work alright?View attachment 362285 In line speed control for use with single speed router or for belt sander when holding small parts with sander inverted
