Note: These values are for HSS cutting tools. For carbide cutting tools, double the cutting speed. These
values still may need slight adjustment depending on the cutting tool rake and relief angles. Refer to the
MACHINERY'S HANDBOOK for more detailed information.

NOTICE
ALWAYS make sure the spindle is turned
OFF and is at a complete stop before
changing any gear configuration to prevent
damage to the lathe gearing and voiding the
warranty.
