Radius Offset Keypad
• Type in the offset amount. An offset amount
of.001 will produce the largest possible radius.
As your offset gets larger the radius will be-
come smaller.
NOTE: It may be more difficult to achieve a
larger radius on drills with split angles
greater than 120°.
The greater split angle, the less apparent
the radius. See view B
• Touch the “SAVE” button to store the
“New” information and transfer you back
to the previous screen.
• Selecting “CANCEL” will delete any
unsaved data, retrieving the most re-
cently saved information, transferring you
back to the previous screen.
Adjusting The C axis
• Adjust the stopping point of the C axis. The
factory default is 5°. This will stop the oppo-
site cutting edge of the drill 5° from the grind-
ing wheel. In most cases, adjustment of the C
axis will not be necessary. Adjustment is nec-
essary only if the C axis rotates too far into
the grinding wheel nicking the cutting edge of
the drill.

creates larger radius. Offset can be from 1% - 50% of web thickness dimension. Dotted lines
indicate large and small radius.
