Sandvik Coromant CoroDrill Delta-C R840 Carbide Drill Bit, TiAlN Finish, Cylindrical no Flat Shank, Helical Flute, 140 Degree Split Point, 3.7mm Size, 28mm Cutting Length

Key features

• Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems
• Right-hand cut tools have a cutting action that engages when they are run in a clockwise direction
• Round shanks allow use with a wide variety of toolholding systems
• Max Hole Depth: 4 - 5 x Dc

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 porta
