I AM HAVING A PROBLEM WITH DRILLING SLOTS. THE LARGER SIZE HOLES ARE NO
PROBLEM BUT ANYTHING UNDER .055 IS GIVING ME CROOKED OR JAGGED LOOKING
SLOTS.  IN THE PAST WE ALWAYS EDITTED ARE DRILL FILES ADDING G85S', BUT
A GREAT DEAL OF OUR CUSTOMERS ARE ADDING SLOTS IN GREAT NUMBERS ALL OVER
THEIR BOARDS. AND ADDING G85S' BECOMES TIME CONSUMING AND LEAVES US OPEN
TO OPERATOR ERROR. I REALIZE THAT FEEDS AND SPEEDS ARE PART OF THE ISSUE
BUT I AM WONDERING UNDER THE SLOT DRILL CHOICE IN ROUT WHICH METHOD IS
THE BEST FOR CREATING SMALL HOLE SLOTS. IT SEEMS WHETHER WE CHOOSE
SEQUENTIAL, ALTERNATING, OR MIDPOINT WE ARE GETTING SOME DEFORMITY.  IF
YOU HAVE ANY SUGGESTIONS IT WOULD BE GREATLY APPRECIATED.

                                        THANK YOU,
