Exactly. Without coolant, even light cuts at twice the recommended speed will quickly dull tooling.
The best surface finish is generally attained by using light, climb cuts at the proper sfpm. Coolant, even if just misted on with a spray bottle will help as well.

Would it be safe to say Carbide Tipped or inserts provide some resistance there? And the inserts are the better option of the 2 types?
Yes clear the chips, keeping the machined area, brushed and hosed down, WD power squirter
CNC machines are like Top Fuel, and my Pro stock machines will never produce the quality for many reasons . But can be tweaked to preform better if the right adjustments are made, and cutting hardware used.
I'm not kidding myself regarding the finish, just want to bring the quality up a few levels. In others words not expecting a mirror finish, but want to smooth out the tool marks more.
My thinking anyway and could be all wet also.
