Product Description

This Chicago-Latrobe 159 series short length drill bit set contains 60 high-speed steel drill bits, including one each of wire gauge sizes #60 through #1, with a black oxide finish and a 135-degree split point for increased rigidity in heavy feed-rate drilling applications on ferrous materials. High-speed steel (HSS) provides hardness for wear resistance, and the black oxide finish acts as a lubricant to reduce wear while promoting chip and coolant flow. Compared to standard drill bits, these tools have a thicker web for increased strength and rigidity. The self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118-degree point. These short length drill bits provide the strength and rigidity that is necessary for heavy-feed rate applications. The round shank accommodates most drill chucks.

The set comes in a gray epoxy-coated index case with labeled compartments for identification and organization. Case measures 4-3/4 x 3-1/2 x 1-1/4 inches (H x W x D). (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.)

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.
