Important Disclaimer: The Accupro speed and feed rates are suggested by the manufacturer as a general guideline. Machine type, horsepower, spindle speed limitations, toolholding & workholding devices all may impact a cutting tool's ability to perform properly. MSC is not responsible for tool failure, part damage or injury that may be caused as a result of the previous mentioned factors.
