For Lighter Radial Depths Of Cut - Higher range of recommended surface speeds should be used.

For Greater Radial Depths Of Cut - Lower range of recommended surface speeds should be used.

For Slotting Applications - Speeds (S.F.M.) should be reduced approximately 20% of the lowest range value.

When using long & extra-long End Mills reduce feed per tooth 50%.

SAFETY REQUIREMENTS:

WARNING: When using solid carbide rotary cutting tools, tools may shatter, wear safety glasses. Use safety shields on machines as applicable. Grinding also causes hazardous dust and fumes - use proper ventilation.
