Screw Machine Length (Stub) Group Code: HSSB These 'stubs' are designed for screw machine operations in which normal drills are too long, making short, rigid drills a necessity. The shorter length reduces breakage and run out. They are especially suitable for N/C drilling applications.	Jobber Length Drills Group Code: HSSB These general purpose and production machine drills, in ferrous or nonferrous materials, feature a thicker web for extended drill life. They are relief-ground and twist-fluted for maximum strength and rigidity.
Taper Length Drills Group Code: HSSB These general purpose drills feature an increased cutting length. The straight shanks have the same diameter as the flute. Also known as ‘Longer Series Drills’ or ‘Long Jobber Drills’, taper length drills are named for having the same flute length as taper shank drills.	Aircraft Extension Drills Group code: AB These drills have the same flute length as jobber length drills and feature an extended shank. Stocked in 6" and 12".
Double Ended Drills Group Code: DED Designed for sheet metal, tubing, and thin section applications, double ended drills are considerably more durable than screw machine drills and last longer with less breakage. They will successfully drill holes in stainless steel and other work hardening alloys.	1/2" Shank (Silver & Deming) Drills Group Code: HSSB These all purpose drills are designed for use when the maximum chuck capacity is 1/2". All S & D drills are 6" overall length with 3" flute length.
