37/64 inch HSS jobber drill bit

The Drill America 37/64in HSS Black Oxide Jobber Length Drill Bit is a new high-speed steel cutting tool for general-purpose metal drilling. Its fractional size suits maintenance, fabrication and automotive tasks that require a precise 0.5781 inch diameter hole.

Black oxide finish and standard jobber geometry

The black oxide surface treatment reduces friction and resists corrosion during repeated use. A flute length of 4-13/16 inches and an overall length of 6-5/8 inches provide standard reach for drill presses and handheld drivers. The straight shank fits common three-jaw chucks without adapters. Builders who need a smaller step size or a longer aircraft-length bit will need a different tool.
