Size of tool, depth of cut, chip ejection {air!}, cooling ... will all dramatically affect tool life. Burying a 1/4" tool into in
a single pass in 3/4" stock with chips obscuring the cut ... yields short life. I've had some 4 flute HSS 1/2"
shank tools .... for years. where typical DOC is 1/8".
and yes, material matters as does surface speed.
