Excellent for something that small.
Almost any good quality miter saw will do but I looked for the lowest blade speed available; I think it is a De Walt.
Get the 'Triple Chip' carbide blade with as many teeth as you can find. These are the blades with alternating square cornered teeth and teeth that have bevelled corners; they will be labelled suitable for nonferrous metal or aluminum. The best blades are the type that have laser cut squiggly gooves in the blade which are filled with a rubbery compound. These are to prevent blade warping if it gets warm and the rubber dampens vibration so they cut very quietly. I think the make if Freud but I am not at the business to go have a look.
Also get a mister to spray a very small amount of coolant on the blade, it helps with the surface finish.
We also made a fixture to hold the material which is a block with a hole that the stock slides thru with the blade coming down through a slot. This way it cannot get lifted and jammed in the blade and the cut off piece is retained in the hole until you advance the stock and push it out.
