Taper Length

HSUMThese drills are designed with a heavy duty web and are recommended
for drilling steel forgings, tough alloy steels and other difficult to machine
materials. The shanks are tanged and may be used in A.S.A. split sleeve
drill drivers. The flute length is longer for deeper holes and more regrinds.
Drill diameters over 1/2” have reduced shanks.
