E E Conversion of selected cutting speed to rotational speed is calculated using the following formulas: INTERNAL THREAD | Roscagem interna | Roscado interno Spindle Speed (rev/min)

Dc - Cutter diameter(mm)

n - Spindle Speed (rev/min)

Vc - Cutting Speed (m/min)

Example for the following values: Vc x 1000 120 x 1000

Vc = 120 m/min n = = = 1274 RPM

This is a general purpose grade, which can be used with all materials, it should be run at medium to high cutting speeds. Recommended Feed Rate: 0.05 - 0.15 mm left hand thread right hand thread
