DRILL LINERS AND INSERTS are
in large demand for precise drilling
and are made to the same high standards
of excellence. They are heat treated
to RC 62-64 and have a concentricity
of .0002 T.I.R. Standards are available
from stock in number, letter and
fractional drill sizes. Specials
can be made upon request.
GUN DRILL LINERS are designed to be used with the replaceable inserts indicated in the table. All type GDL Bushings are ground concentric within .0002 .T.I.R. The heads are undercut and square with outside diameters so the liner will seat flat against the chip box. |
