Use adequate feed, .003” (.08 mm) to .006” (.15 mm) per revolution thereafter, to
establish a continuous chip cut.
If the feed is too light, only light stringer chips will be removed.
If the feed is too heavy, the drive will start to overload and the chip will start to
have a rough or torn appearance.
Stainless, which work hardens, must be worked with a heavy enough feed to
stay under the work hardened surface, .003" (.08 mm) to .006" (.15 mm) feed.
Never allow the Tool Bit to burnish the surface.
A good rule of thumb for calculation purposes is a .0025" (.064 mm) thick chip
per revolution. Actual measurements wil show a pseudo thickness of .006"
(.15 mm) unless a pin micrometer is used for measure.
One revolution of the feed handle advances the Cutting Head .100" (2.5 mm)
