Jobber Bit for General Drilling
This Chicago-Latrobe drill bit is a jobber-length tool made from high-speed steel for general-purpose drilling. It suits machinists, maintenance technicians and DIY users who need a reliable fractional-size bit for metal, wood or plastic work.
Black Oxide Finish and Conventional Point
The black oxide coating adds corrosion resistance and helps retain cutting fluid during use. A conventional 118-degree point with no coolant holes means the bit is designed for handheld or stationary drilling where through-coolant is not required.
Check Chuck Capacity and Material Suitability
Verify that your drill chuck can accommodate the .6719-inch decimal shank before ordering. Buyers who need coolant-through capability or a split-point design for self-centering on hard metals should note this bit lacks those features.

Questions about this item
What drill-point standard does the 118° angle follow?
The 118° conventional point is the standard geometry for general-purpose drilling in steel, cast iron and non-ferrous metals.
What chuck capacity is required for the 43/64" shank?
The .6719-inch decimal shank needs a 3/4-inch or larger drill chuck to seat fully.
How should the 43/64" jobber bit be started to avoid walking?
Center-punch the mark, keep the bit perpendicular, and begin at low RPM with steady axial pressure until the 118° point engages.
