CUTTING SPEEDS
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 of
the 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 thin-wall mild steel and tube with coolants.
When facing over a mounting hole pattern in a flange, machine speed should be
reduced to lessen the impact on the cutting edge of the Tool Bit and to prevent ripping
the edge of the holes.
Tool Bit feed rate is dependent on the flange material and the type of finish required.

Smooth finish: .013” (.3 mm) feed (one tripper engaged).
