Ok, for starters, your RPM looks about right for the material and endmill size. You should be running at least 0.001" per tooth or 0.002" per revolution (36" per min ~ 1m/min), so you need to turn up the feedrate. This all assumes a nice, rigid setup and 6061 T6 wrought alloy. If that's not the case, you need to adjust the speed down to meet the feedrate. You need to know the alloy with which you are working and look up the standard hardness for that alloy. It may not be exact to your application, but it will give you a place to start.
As far as cutting fluid is concerned, kerosene works very well for aluminum. You can put some in a squirt (not spray) bottle and apply it that way. I apologize, but I do not know any machinery supply houses in the UK, but a water soluble synthetic lube is what I use in my mist cooler. Mix it to the instructions on the bottle. $20 a gallon here in the US.
