💡 Carbide vs HSS end mills, which should I buy?

It comes down to the machine, the material and the budget.

• Carbide runs faster and lasts longer, especially on CNC machines.
• HSS and cobalt end mills are tougher and cheaper for manual mills.
• Coatings like TiAlN and AlTiN add heat resistance for hard steels.
