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.
TAPER LENGTH DRILLS - FRACTIONAL SIZES
For general purpose drilling where a longer than jobbers length drill is required.
For heavy duty drilling in tough alloy steels, forgings, and casting.
For deep hole drilling in hard steels, stainless steels, and other hard materials. Mfr. to NAS 907-B specs.
For deep hole drilling in a wide range of materials especially aluminum and mild steel. Parabolic flutes ease chip ejection. These drills are also known as Worm Pattern Drills.
For drilling cast iron and non-ferrous material.
For applications where a longer than jobbers length drill is required. The tanged shanks are for use with positive drive split sleeve drivers.
For deep hole drilling low tensile strength materials such as aluminum, magnesium, copper, zinc, and similar materials producing long stringy swarf. Excellent chip-clearing.
