Metric Size HSS Extra Length Drill Bits

* High Speed Steel Straight Shank Metric Extra Length (Long Boy) Drills with a
118 degree point are designed for drilling very deep metric size holes in ferrous
or non-ferrous metals or drilling in difficult to reach locations. Straight shank
extra length drills are preferred for drilling small to medium diameter deep metric
size holes as they do not require as much rotational power for drilling that a large
deep hole would require. They are also known as Metric Contractor's Long Boy Drills
or simply as Metric Long Boy Drills.
* Industrial grade cobalt high speed steel are available on request.
* Right hand cutting direction; standard two flute design.
* Black oxide finish or Bright finish are available on request.
