Drillco 1000EC220 1-5/16

Description

The bronze finish lubricates the drill bit and provides wear resistance. Drill bits come in a variety of lengths and types, the most common of which is the twist drill bit. The drill bit conforms to American National Standards Institute (ANSI) specifications.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 shank with flats ground onto three sides reduces slippage of the bit when used in drill chucks. The helical twist of the flutes brings chips up and away from the cutting edges and allows for coolant to reach the cutting edges. 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.Drillco manufactures cutting tools such as drill bits, reamers, taps, dies, annular cutters, end mills, and. Mechanic's length twist drill bits (also called maintenance length) are a little shorter than jobber length and less prone to deflection when drilling. The Drillco 1000EC series reduced-shank drill bit is made from cobalt steel with a bronze finish and has a 135-degree split point for use on tough, high-tensile strength metals. 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. The company, founded in 1978, is headquartered in Baton Rouge, LA.

Key Features

• Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures.
• The helical twist of the flutes brings chips up and away from the cutting edges and allows for coolant to reach the cutting edges.
• 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.
• The Drillco 1000EC series reduced-shank drill bit is made from cobalt steel with a bronze finish and has a 135-degree split point for use on tough, high-tensile strength metals.
• The bronze finish lubricates the drill bit and provides wear resistance.
• The reduced shank drill bit, also called a Silver and Deming drill bit, has a shank that is smaller in diameter than its shaft, permitting drilling with a 1/2" drill chuck.
