re-grinding
button
drill
Fixed
grinding
program
usually
brings
good
work
habits
.
For
example
,
check
bits
,
and
then
again
at
the
shift
end
milling
or
after
a
certain
number
of
holes
.
Premature
grinding
is
not
necessarily
uneconomic
,
because
less
needs
worn
carbide
.
It
is
better
to
re-grind
rather
than
reduce
productivity
due
to
damage
.
Correct
grinding
greatly
increases
the
service
life
of
the
drill
bit.
But
equally
important
,
it
also
improves
the
performance
of
the
entire
drilling
operation
,
especially
straightness
of
the
hole
