Kodiak Cutting Tools KCT131558 USA Made Solid Premium Carbide End Mill, ALTiN Coated, 4 Flute, 0.6cm Diameter

Can someone double check for me that the shank width IS 1/4 inch? I bought another end mill off of amazon and it was 6mm instead of 1/4 in

can this be used on a regular hand drill?

I can't find this part number on kodiak's website. it also lacks kodiak's etched name on the tool as well. is this a real kodiak tool or a knockoff?

Is this a center cut end mill?
