aircraft extension drill
Aircraft Extension Drills are heavy duty jobber flute length drills used for drilling holes in hard to reach places. Extended overall lengths of 6", 12", and 18" are common, with longer lengths of 24" or more also available. They are manufactured to NAS 907 drill standards. ICS Aircraft Extension Drills have heavy duty 135° split points except where indicated.
Other types of Extension Drills are available here.
