The These carbide tools are durable and well machined, the wear resistance is quite good as tool life lasted 1h20 in Z40 stainless steel AP6mm AE4mm 0.05mm/tooth 2900tr/min with a Rough 12mm endmill. The tool geometry is more suitable for steel than aluminum. The only thing that seems useless is the "nano coating", it will disappear as soon as you start machining, it looks like blue paint and will flake away if you scratch it with a knife.
