Jobber Drill Bits (FRACTIONAL)
Jobber-length drills are the most common type of drill bit. The length of the flutes is ten times the diameter of the drill, meaning they will drill a hole that is 10D deep. These high performance twist drill bits are suitable for all normal drilling in conventional materials. Available in High Speed Steel,Colbalt, and Titanium Nitride-coated (TiN-coated) High Speed Steel, the added titanium nitride coating increases the surface hardness to approximately 2300 HV and the heat resistance to 1100°F (600°C). /Asset/206US_Superba.jpg Jobber Drill Bits (METRIC)

Wire Size or Numbered Drill Bits, represent the diameter of the drill bit. The jobber drill bit is theis the most common type of drill bit. You will find that the length of the flute of the drill is a total of 10 times the full diameter of the actual drill. A dependable, general purpose drill designed to perform in a broad range of material in the iron and steel families. Ideal for production, maintenance or portable drilling jobs /Asset/D_AN_Jobber.jpg Cobalt Drill Bits
Cobalt jobber drills are the preferred option for experienced mechanics in many diverse fields such as lock-smithing, HVAC, automotive trades, machinery repair, etc. Because of their capacity to drill through tough materials, the need to change bits is minimized; and, because of the 135 degree split point, they work as well in the field as in the shop. High cobalt alloy tool steels are best known for having excellent wear and corrosion resistance over a wide variation of temperature ranges. /Asset/D_ACO135.jpg Mechanics Drill Bits (3 Flats Shank)
Stanley Supply's Mechanics' length drills have a 135º split point for self-centering and are marginally shorter than standard jobber drills, producing a more rigid drill, particularly suited to hand-held operation. Black and Gold surface for use in work-hardening stainless steel and other tough metals. 3-Flat shank, on sizes 3/16" and larger. /Asset/KFDML_Superba.jpg Stubby Drill Bit (Screw Machine)
Short length drill bits, often used in screw machines. Often called "stub drills". Shank is the same diameter as cutting diameter.High speed steel.The short-stub length has more rigidity for drilling straighter, shallower holes than Jobber-length bits. Screw Machine Drill bits may be bright finished or black oxide, /Asset/stub-length.jpg Doubled End Stub Drill Bits
1/8" High Speed Steel Double Ended Split Point Drill Bit. 1/8" Doubled ended M2 High Speed Steel Stub Drills. 1/4" Flute Length. Great for industrial, automotive and carpentry work. 135 split point. Fast starting bit. Like having 2 drill bits in one. /Asset/D_ADE_StubFluted.jpg Silver Demming Drill Bits ( S&D)
Silver and Deming drill bits have straight shanks smaller than the diameter of the bit. Another name is the reduced-shank drill bit. Generally, this bit is 6 inches long and consists of a ½-inch shank with a 3-inch flute. Silver & Deming apparently invented the large-size twist drill bit with a turned-down shaft so they can be used in a chuck smaller than the bit's cutting diameter. They did not patent this idea, so the idea was quickly copied by others, but these bits are still called "Silver & Deming drills". /Asset/201US.jpg Extra Long Drill Bits (Aircraft Length)
Stanley Supply carrries an extensive line of Aircraft Extension Drills Bits in 6" and 12"-lengths, as well as in High Speed and Cobalt. These drill bits have a 135° split point (in sizes 1/16" and over and down to #52 in wire gauge size For those deep, hard to reach holes /Asset/213SP.jpg
