Carbide vs. HSS End Mills for Aluminum Machining Which to Choose?

[howida]

Hello,

I am currently working on a project that involves CNC machining aluminum parts; and I'm trying to decide between carbide and high-speed steel (HSS) end mills.

I have read that carbide can provide better surface finishes and higher cutting speeds; but they are also more expensive. On the other hand; HSS end mills are more affordable and easier to re-sharpen.

Could anyone share their experience or advice on which type would be more cost-effective and efficient in the long run for aluminum machining?
Are there specific scenarios where one outperforms the other? I have referred https://www.mycncuk.com/forums/11-Tool-Tooling-Technology- guide but still need help .



Additionally; any recommendations on specific coatings ; brands that have worked well for you would be appreciated!


Thank you
