Adding to .250 Single O flutes Cutters numbers

Hello, I was hoping several of you guys that cut hard plastics. In my case PVC sheets and aluminum sheets. I know the O flute can cut both nicely. I’m adding two different 1/4” single O flute tool to PVC category and in my aluminum tool libraries. I’ve downloaded the spec sheets.
First is Amanda Tools 45777-k 0.250” end mill and Spetool 0.250 O flute end mill WC3001 and longer version wc3003.
