Drill America DWD29J-CO-PC 29 Piece M35 Cobalt Drill Bit Set in Round Case Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Drill America - DWD29J-CO-PC 29-Piece M35 Cobalt Drill Bit Set in Round Case (1/16" - 1/2" X 64ths), DWDCO Series

The Drill America DWD29J-CO-PC Qualtech jobber length drill bit set contains 29 cobalt steel drill bits with a gold oxide finish in inch sizes ranging from 1/16" to 1/2" (1/64" increments). The set comes in a plastic index case with labeled compartments for identification and organization. Drill bits conform to American National Standards Institute (ANSI) standards.

Cobalt steel provides extended tool life compared to high-speed steel drill bits when drilling hard materials, and the gold oxide finish lubricates the drill bit and provides wear resistance. The self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips, reducing clogging compared to a 118-degree point.

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. The round, twisted shaft of the twist drill bit typically has two cutting edges and flutes, with the helical twist of the flutes bringing chips up and away from the cutting edges and allowing for coolant to reach the cutting edges.

Jobber length twist drill bits 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, while short length twist drill bits (also called stub or screw-machine length) are the shortest and stiffest, 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, and extra long twist drill bits (also called extension) are longer than long length twist drill bits for greater reach or for drilling deeper holes.

Drill America manufactures a variety of cutting tools, including drill bits, taps, dies, counterbores, countersinks, end mills, and reamers. The company, founded in 1927, is headquartered in Miami, FL.
