Adjust that to read without destroying anything to expensive... Your gonna destroy a few end mills and carbide inserts... There's definitely a learning curve... Long as you don't crash anything to serious it's normal... My first year I probably killed a couple hundred bucks worth of tooling... But never hurt the mill table, mill vise or any part of the head.... These days I'm much better but last week I broke two endmills... Of course when you get down to using 3/32" endmills they break really easy...
