Size
Tungsten carbide burrs come in a variety of sizes to suit different applications. Choosing the right size will depend on the job at hand. Generally smaller burrs are used on smaller applications for producing finer, smoother work. Larger burrs are for higher, faster stock removal and are more often used on larger jobs.

Speed
The rotary tool speed you use will depend on the metal and size/type of burr used. For optimum performance and results it is always best to check the manufacturer recommendations for the correct RPM to use with each metal burr. Ideally you will start off at a lower speed and increase as you go along, however if you find your burr is chipping it is a sign you are going too slow. Here is a general rotary tool speed guide

Technique
For the best results, and to make your burr last longer, make sure you don't use too much pressure while cutting. Too much pressure will cause the cutting edges of the flutes to chip and become smooth prematurely, reducing the life of your burr .

You will also want to ensure you keep the burr moving around the cutting area as much as possible. If the metal burr is left still for too long this can cause clogging and stop it from digging and jabbing into the job, leaving a rough job with visible marks.
