The Cutting Speeds are approximately
Use 200 surface inches per minute (5080 surface millimeters per minute) for:
Stainless steels in general when no coolant is allowed, all heavy-wall tube
and some chrome/molybdenum steels.
Use 250 surface inches per minute (6350 surface millimeters per minute) for:
Mild steels and some thin-wall stainless steels when coolants are permitted
and applied.
Use 300 surface inches per minute (7620 surface millimeters per minute) for:
Aluminum and some thin-wall mild steel and tube with coolants.
Inconel and some other high-temperature alloys may require special procedures
as a function of wall thickness and type of end preparation. Contact TRI TOOL’s
Engineering Department for details.
