End mill as a slitting saw, practical smallest diameter

Manual mill BP, even using coolant: My direct experience I'd guarantee you'll give up even using 1/8" end mills due to breakage combined w the slow going (I didn't give it much a chance once I realized it'd be fruitless for me to try finesse the speed feed to magically make that sort of 1/16"-1/8" endmill "slitting" work really well, and it takes a LONG time manually).

Cutting generates a lot of heat, making oil based coolant preferable. Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low. If not using coolant, then max surface speed is 50 ft/min. Insulation
