||The gun drilling process was
originally developed for producing the gun
barrel requiring a straight deep hole. With
the considerable progress in the automotive
industries, gundrill technology was more advanced.
Gundrill is a necessary tool for the straight
deep hole drilling process. It is widely used
in the various field such as the automotive,
ship, aircraft, machine & tool making,
oil and mold industries because it has lots
of good points such as high cutting performance,
high precision alignment and straightness,
and good surface machining.
Single Flute gundrill is able to machine
a straight deep hole because it is designed
to easily discharge the leftover chip with
high oil pressure. Dongsan can manufacture
a Single Flute gundrill in diameter from
2 to ~50 mm and machine a straight deep
hole up to 100 x's dia.and greater.
