Product Details

  • Jobber length drill bit has a midrange drilling depth of 4 to 5 times its diameter for general-purpose applications
  • Solid carbide drills produce close-tolerance holes in hard materials, and have a longer tool life at higher speeds than cobalt and high-speed steel (HSS)
  • Diamond coating creates a low-friction surface for extended tool life when dry drilling in carbon fiber-reinforced plastics (CFRP)
  • Specially designed drill-point geometry has dual cutting angles for prolonged tool life, and penetrates composite materials while without causing delamination
  • Drill bit conforms to DIN 6537 standard, and the round shank conforms to DIN 6535 HA standard


The Sandvik Coromant CoroDrill 856 series jobber length drill bit is made from solid carbide with a diamond coating and has a 130-degree point for use in general-purpose dry drilling applications on composite materials, such as resin-rich CFRP, thermoset plastics, and materials with a glass skin. The 130-degree point has a dual cutting point that prolongs the tool life and prevents delamination of the composite being drilled. 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 diamond coating provides a low-friction surface for extended tool life. This jobber length drill bit has a versatile midrange drilling depth of 4 to 5 times its diameter and is a common choice for general-purpose applications. The round shank accommodates most drill chucks. The drill bit conforms to Deutsches Institut für Normung (DIN) 6537 standard, and the round shank conforms to DIN 6535 HA standard.

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.

Sandvik Coromant manufactures tools for turning, milling, and drilling. The company, headquartered in Sweden, makes tools used throughout the metalworking field, including the automotive and aerospace, die and mold, and general engineering industries.
