They're ~$35 for a 1/2" end mill which may be expensive depending on what kind of tooling youve been purchasing, but they're a great deal for us, since the previous 1/2" end mills I've been purchasing were ~$45 for 2 flute TiN coated carbide. |
It’s cheaper then what we were buying last year, more expensive compared to most of what we bought this year.
Just wondering, what exactly is a 'variable helix'? On their site the end mills look to have a very consistent helix to them, I can't see such a subtle change to make any real difference.
