Cleveland 1727 Solid Carbide Jobbers' Length Drill Bit - Uncoated Bright Finish, Round Shank, 118° 4-Facet Point, 7/16" (1-Pack) - Perfect for Metalworking, Woodworking & DIY Projects

The Cleveland 1727 series jobber length drill bit is made from solid carbide with an uncoated (bright) finish and has a 118-degree 4-facet point for general-purpose drilling applications on a range of hard materials. Solid carbide is harder than high-speed or cobalt steel, provides longer tool life at higher speeds, and produces close-tolerance holes in hard materials. The uncoated finish has no additional surface treatment or coating. The self-centering 118-degree 4-facet point provides durability and accuracy to prevent walking and penetrate the material more easily than a conventional point. Compared to standard drill bits, these tools have a thicker web for increased strength and rigidity. The drill bit has a slow spiral (also known as a low helix angle) with elongated flutes for improved strength and rigidity compared to standard drill bits. A jobber length drill bit has a versatile midrange drilling depth and is a common choice for general-purpose applications. The round shank accommodates most drill chucks. The drill bit conforms to American National Standards Institute (ANSI) standards. 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 for 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 twist drill bits (also called Silver and Deming drill bits) have a shank that is smaller in diameter than its shaft, permitting drilling machines with a 1/4", 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 length twist drill bits (also called extension) are longer than long length twist drill bits for greater reach or for drilling deeper holes.Cleveland manufactures tools for drilling, threading, and milling applications. The company, headquartered in Seneca, SC, meets International Organization for Standardization (ISO) standard 9001.
