Description
The Drill America DWD29J-CO-PC Qualtech jobber length drill bit set contains29 cobalt steel drill bits with gold oxide finish in inch sizes 1/16″ to 1/2″(1/64″ increments). A self-centering 135-degree split point penetrates hardmaterial without a pilot hole and produces smaller chips that reduce cloggingcompared to a 118-degree point. Cobalt steel provides extended tool lifecompared to high-speed steel drill bits, and maintains the tool’s toughnessand hardness in high drilling temperatures. A gold oxide finish acts as alubricant and provides wear resistance, and the round shank accommodates mostdrill chucks. The set comes in a plastic index case with labeled compartmentsfor identification and organization. Drill bits conform to American NationalStandards Institute (ANSI) standards. Drill bits are cutting tools used tomake holes in a range of materials using machines such as handheld portabledrills, machining centers, and lathes. Drill bits come in a variety of lengthsand types, the most common of which is the twist drill bit. The round, twistedshaft of the twist drill bit typically has two cutting edges and flutes. Thehelical twist of the flutes brings chips up and away from the cutting edgesand allows for coolant to reach the cutting edges. Jobber length twist drillbits, the most common length of twist drill bit, offer a good compromise oflength and reach to work with the widest range of materials and applications.Mechanic’s length twist drill bits (also called maintenance length) are alittle shorter than jobber length and less prone to deflection when drilling.Short length twist drill bits (also called stub or screw-machine length) arethe shortest and stiffest twist drill bits, helping to reduce the chance ofdeflection or breakage when drilling. Reduced shank drill bits (also calledSilver and Deming drill bits) have a shank that is smaller in diameter thanits shaft, permitting drilling machines with either a 1/2″ or 3/4″ drill chuckto
