Sharp 3 flute endmill comes in a plastic sleeve with a cap that holds the shank for safe storage. The 5/16 round shank measures about 1 1/4" long so there is room to get a collet on it. Total tool length is just under 2". Good for milling aluminum and similar non ferrous metals.

This little end mill exceeded my expectations. Good price aside, it performed as well as the one you are probably looking for to complete your garage build project. The other Amazon options are 1/2 inch too long and this 2” mill was a perfect replacement. The shank was exactly the right diameter to 4 decimals out (measured digital calipers). It fit the adapter like a glove.Really impressed with the durability. The cut was consistently smooth. The finishing was great for the first two aluminum units I completed. During the third unit, the tips of the flutes started to show the carbide instead of the coating but I suspect it was letting someone else use it and they were feeding a little too aggressively. I suspect it would have worked for at least 4 units before needing replaced.Just buy it and save the extra $30 from green colored OEM. Buy yourself a nice rubberized grip with the savings.

It works fine. It may be wearing faster than I expect but no issues.
