Rheostat

Hi everyone. I am new to the forum. I want to install my 18 V angle grinder to my skateboard. I just need to know how I can vary the RPMs.
I would still like to use my grinder as a grinder when I need it. So I don't want to chop it up and dissect it persay . So is there some sort of potentiometer I could install in line with the battery and motor externally so that I could hold it in my hand that has a wire going down to the grinder while I am riding?
Thank you
