    Today I tested 50HRC 3 flutes end mill for aluminum. It was very very good. Cuts very good. It barely makes a sound.If you stop watching the machine, you cannot say it is cutting.

Product Description

3 Flute Carbide Aluminum End Mill With DLC Coating 10mm Aluminium Milling Bits


End mills for aluminum are often available in either 2 flute or 3 flute styles.

With higher flute counts, it would become difficult to evacuate chips effectively at the high speeds at which you can run in aluminum.

This is because aluminum alloys leave a large chip, and chip valleys become smaller with each additional flute on an end mill.
