31/64" Screw Machine Length Fractional Drill Bit, 2-3/16" Flute Length, Black Oxide Finish

Manufactured to National Aerospace Standard 907, Type C. Heavy duty construction and shorter length, performs well in stationary and portable drilling Shorter flute and overall length increases the rigidity resulting in less deflection, better hole accuracy and longer tool life 135 split point is self-centering and reduces thrust Designed for drilling in a broad range of materials in the iron and steel families.
