Chicago-Latrobe 44033 Jobber Drill
The Chicago-Latrobe 44033 is a jobber-length drill bit sized at 33/64 inch with a 118-degree point angle. It is made from high-speed steel with a black oxide finish for general-purpose drilling. Machinists and maintenance technicians reach for this fractional-inch bit when they need a standard-length tool for steel, cast iron or similar materials.
Sustained drilling behaviour
The conventional 118-degree point centres quickly and holds its geometry through repeated holes. High-speed steel resists softening when heat builds during extended runs, while the black oxide surface reduces galling and helps retain cutting fluid. The bit has no coolant-through channels, so external lubrication is required for deep or continuous cuts.
Build and daily use
The 0.5156-inch decimal equivalent fits standard three-jaw chucks without sleeves or adapters. Black oxide coating adds corrosion resistance for shop storage and simplifies chip evacuation in sticky alloys. Because the flute length follows jobber proportions, the bit clears swarf efficiently in through-holes but is not optimised for extra-deep drilling.

Questions about this item
How much heat does the 118-degree point generate when drilling 33/64-inch holes all day?
The conventional 118-degree point on high-speed steel is designed for general-purpose cutting; steady feed pressure and cutting fluid keep temperatures manageable during extended use.
What tool holder do I need for the .5156-inch shank on this bit?
The fractional 33/64-inch shank fits standard three-jaw drill chucks rated for 1/2-inch capacity or larger.
Will the black-oxide 44033 bit work in my older drill press that only takes straight-shank jobbers?
Yes, the straight jobber-length shank matches the taper-free holders found on vintage drill presses.
