• Designed for drilling cast iron, cast steel, bronze, hard copper, aluminum, and other hard nonferrous materials
• Jobber length drill bit has a midrange drilling depth
• Carbide-tipped high-speed steel is more wear resistant than high-speed steel
• Uncoated (bright) finish has no additional surface treatment or coating
• 118-degree conventional point for general-purpose drilling applications

The Drillco 600 series jobber length drill bit is made from carbide-tipped high-speed steel and has a 118-degree conventional point for drilling cast iron, cast steel, bronze, hard copper, aluminum, and other hard nonferrous materials. The jobber length drill bit has a versatile midrange drilling depth and is a common choice for general-purpose applications. Carbide-tipped high-speed steel (HSS) is more wear resistant than high-speed steel, and the uncoated (bright) finish has no additional surface treatment or coating. The round shank accommodates most drill chucks. 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. 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.

Drillco manufactures cutting tools such as drill bits, reamers, taps, dies, annular cutters, end mills, and burs. The company, founded in 1978, is headquartered in Baton Rouge, LA.
