Feature

●Spotting drill bit creates a pilot hole to reduce walking and improve hole accuracy
●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)
●Uncoated (bright) finish has no additional surface treatment or coating
●90-degree conventional point chamfers and drills a pilot hole to accurately guide the second drill bit with a slightly smaller diameter
●Round shank accommodates most drill chucks
●Made in the USA


Description

The Chicago-Latrobe 790 series regular length spotting bit is made from solid carbide with an uncoated (bright) finish and has a 90-degree conventional point for drilling a pilot hole and creating chamfers into hard 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 uncoated finish has no additional surface treatment or coating. A spotting drill bit is used to drill a pilot hole, which reduces walking and improves hole accuracy for the secondary drill bit. This spotting drill bit has a 90-degree conventional point that chamfers and drills a pilot hole to accurately guide a second drill bit with a slightly smaller diameter. The round shank accommodates most drill chucks.
