Sandvik Coromant CoroDrill Delta-C R840 Carbide Drill Bit, Jobber Length, Multilayer Finish, Round Shank, Coolant Through, 140 Degree Point, 7.4mm Size, 53mm Cutting Length

Key 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
• Coolant-through channels internally guide coolant to the drill bit tip for high feed rates and speeds and continuous clearing of chips
• Drill bit conforms to DIN 6537 standard, and the round shank conforms to DIN 6535 HA standard

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. 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 has internal channels that guide coolant through the body to the drill bit tip for high feed rates and speeds and continuous clearing of chips from the cutting edge. To utilize the coolant-through feature, the drilling machi
