Split the point
Press Chuck slowly and firm-
ly into the Splitting Port until
it stops. Remove the chuck,
rotate one-half turn, and
repeat.
Check the tip of the bit care-
fully to determine that both
sides of the bit are split equal-
ly. Compare it to this illustra-
tion. If it does not match,
study the information below.
Split lines are nearly straight
across.
Solution
More grinding is needed for larg-
er drill bits. If one side of the bit
is undersplit, insert the Chuck
into the Splitting Port again and
split both sides. Push the Chuck
into the Port until it stops.
Repeat until the split sides are
equal and look like the correctly
split bit shown above.
