  • GUN DRILL LINERS
    Type GDL

GUN 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.
