R454 - Solid Carbide Jobber Drill Bit (Metric)
R454 series jobber length drill bit is made from solid carbide with a TiAlN coating and has a 140-degree split point for use in general-purpose drilling on ferrous materials, high-temperature alloys, and titanium.
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 titanium aluminum nitride (TiAlN) coating provides wear and corrosion resistance in high-speed or heavy feed-rate drilling.
A self-centering 140-degree split point penetrates hard material without a pilot hole, and produces smaller chips that reduce clogging compared to a 118-degree point.
This jobber length drill bit has a versatile midrange drilling depth of 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 L standar
