taper length drill - side and front view
Taper length drills are general purpose drills with increased cutting length. They are manufactured with straight shanks of the same diameter as that of the flute diameter. Taper length drills derive their name from having the same flute length as taper shank drills. In Europe, these drills are known as Long Series Drills or Long Jobber Drills.
