Chicago-Latrobe 44220 Jobber Drill Bit
This Chicago-Latrobe 44220 drill bit is a general-purpose cutting tool designed for machinists and maintenance technicians. It features a conventional point geometry suitable for a wide range of standard drilling applications in the workshop.
5/16 Inch Capacity and High-Speed Steel Construction
The bit offers a 5/16 inch diameter with a decimal equivalent of .3125 inch, crafted from High Speed Steel for durability in ferrous and non-ferrous materials. Its bright uncoated finish performs well in general purpose drilling but lacks the wear resistance of coated alternatives for high-volume production runs.
118 Degree Point Angle and Jobber Length Constraints
The 118 degree point angle provides effective centering for general use but is less aggressive than split-point designs for hard materials or deep holes. The jobber length flute limits reach compared to taper or aircraft extension drills, and the absence of coolant holes requires external lubrication for deeper cuts.

Questions about this item
Will the 5/16 in shank fit the chuck on my older drill press?
The bit has a 5/16 in diameter shank; any chuck that opens to at least 0.3125 in will accept it.
How can I confirm the 118 degree point is cutting correctly after I start drilling?
A properly sharpened 118 degree conventional point produces clean chips and a round hole without wandering.
Does the 44220 come in a case or do I need to buy storage separately?
The bit is sold individually with no case included; a protective sleeve or index must be purchased separately.
