Old machinist at the sharpening shop told me to check my coolant concentration with a refractometer instead of guessing, and after 6 months of ruined inserts I finally bought one.
He showed me how the reading was off by 4% from what I thought it was and a box of $120 CNMG inserts later I'm wondering what else I've been doing wrong, has anyone else had a basic habit completely wreck their tool life?

Jeez, I used to just eyeball it. Guess I owe the tool guy an apology.

Did you at least manage to not mess up your project though?
