Drilling speeds and feeds are based on jobber length drills.
For deep hole drilling reduce speeds by 10% for 3xDiameter,
20% for 4xDiameter, 30% for 5xDiameter and 40% for over
6xDiameter.
Important Disclaimer: The Accupro speed and feed rates are suggested by the manufacturer as a general
guideline. Machine type, horsepower, spindle speed limitations, tooldholding & workholding devices all may impact
a cutting tool’s ability to perform properly. MSC is not responsible for tool failure, part damage or injury thatmay be
caused as a result of the previous mentioned factors

FORMULAS
RPM = (SFM x 3.82)/tool diameter
IPM = number of flutes x RPM x chip load per tooth
The chart is a starting point based on a coated tool.
Reduce rates up to 50% using an uncoated tool.
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.
