Chicago Latrobe 110 Series High-Speed Steel Taper Shank Drill Bit Set In Metal Case, Black Oxide Finish, 118 Degree Conventional Point, Inch, 16-piece, 49/64" - 1" in 1/64" increments

This Chicago-Latrobe 110 series taper shank drill bit set contains 16 high-speed steel drill bits, including inch sizes 49/64" through 1" in 1/64" increments, with a black oxide finish and a 118-degree conventional point for use on ferrous materials. High-speed steel (HSS) provides hardness for wear resistance, and the black oxide finish reduces wear while promoting chip and coolant flow. The drill bits have a #3 Morse taper shank, except for 49/64" and 25/32" drill bits, which have a #2 Morse taper shank. The shank is made to American Morse Standard dimensions and installs directly into a tool's spindle, sleeve, or socket of the same taper for a tight, self-holding fit. The set comes in a metal case with labeled compartments for identification and organization.Drill bits are cutting tools used to make holes in a range of materials using machines such as handheld portable drills, machining centers, and lathes. Drill bits come in a variety of lengths and types, the most common of which is the twist drill bit. The round, twisted shaft of the twist drill bit typically has two cutting edges and flutes. The helical twist of the flutes brings chips up and away from the cutting edges and allows for coolant to reach the cutting edges. Jobber length twist drill bits, the most common length of twist drill bit, offer a good compromise of length and reach to work with the widest range of materials and applications. Mechanic's length twist drill bits (also called maintenance length) are a little shorter than jobber length and less prone to deflection when drilling. Short length twist drill bits (also called stub or screw-machine length) are the shortest and stiffest twist drill bits, helping to reduce the chance of deflection or breakage when drilling. Reduced shank drill bits (also called Silver and Deming drill bits) have a shank that is smaller in diameter than its shaft, permitting drilling machines with either a 1/2" or 3/4" drill chuck to create large holes. Long length twist drill bits (also called taper length) are a little longer than jobber length, allowing for deeper holes and longer reach. Extra long twist drill bits (also called extension) are longer than long length twist drill bits for greater reach or for drilling deeper holes.Chicago-Latrobe manufactures drill bits and accessories, reamers, countersinks, and blanks. The company, founded in 1890 and headquartered in Clemson, SC, meets International Organization for Standardization (ISO) standard 9001.What’s in the Box?16 drill bits, inch sizes 49/64" through 1" in 1/64" incrementsMetal case
