Chicago-Latrobe 44193 HSS drill bit
This Chicago-Latrobe 44193 drill bit is a jobber-length cutting tool made from high-speed steel with a black oxide finish. It features a conventional 118-degree point angle and a decimal size of .3860 inch. The bit is designed for general-purpose drilling in metal, wood and plastic. It suits both professional mechanics and DIY users who need a reliable replacement bit.
Suited for general workshop drilling tasks
The bit suits machinists and maintenance technicians who need a standard high-speed steel jobber bit for handheld or press drilling. The 118-degree point works well in mild steel, aluminium and non-ferrous materials. Builders who need cobalt alloy for hardened steel, carbide-tipped bits for abrasive composites, or coolant-through capability for deep-hole production should look at something else. The letter-size .3860 diameter also limits use to that specific hole requirement.
Consistent wear resistance under sustained cutting
High-speed steel construction maintains hardness during extended drilling cycles, preventing rapid dulling when feed rates are correct. The black oxide surface reduces galling and helps retain lubricant during repeated passes. Under continuous load the conventional 118-degree point distributes cutting forces evenly, avoiding the chipping seen on aggressive split-point designs. Heat builds gradually in the flute rather than at the tip, giving predictable tool life across a full shift.

Questions about this item
What chuck capacity does my drill need to hold the .3860 inch shank on the 44193 bit?
The 44193 bit has a .3860 inch shank, so your drill chuck must open to at least 3/8 inch to grip it securely.
Will the 118 degree conventional point on the 44193 bit start cleanly in the same materials as my older split-point bits?
The 118 degree conventional point on the 44193 bit walks more on hard steel than a split-point design, so you may need a centre punch for accurate starts.
How can I confirm the 44193 bit is cutting correctly after I start drilling?
The 44193 bit should produce continuous, straw-coloured chips in steel and run without chatter; blue chips or squealing mean the 118 degree point is overheating.
