Sandvik Coromant CoroDrill Delta-C R840 Carbide Features

• 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)

• Multi-layer coating of titanium nitride (TiN) over titanium aluminum nitride (TiAlN) provides wear resistance and detection, corrosion resistance, and high hardness for extended tool life

• Round shank conforms to DIN 6535 HA standard, and accommodates most drill chucks

• Drill bit conforms to DIN 6537 standard

About Sandvik Coromant CoroDrill Delta-C R840 Carbide

The Sandvik Coromant CoroDrill Delta-C R840 series jobber length drill bit is made from solid carbide with a TiN and TiAlN multi-layer coating and has a 140-degree point for use in general-purpose drilling applications on a range of materials, including ferrous and other difficult-to-machine materials. 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 multi-layer coating of titanium nitride (TiN) over titanium aluminum nitride (TiAlN) provides wear resistance and detection, corrosion resistance, and high hardness for extended tool life when drilling. The 140-degree point has a point geometry that easily regrinds to restore the cutting edges. A 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 s
