Chicago-Latrobe 44237 Jobber Drill Bit
This Chicago-Latrobe 44237 jobber drill bit is a 37/64 inch high-speed steel tool designed for general-purpose drilling in metal, wood and plastic. It suits professional mechanics, maintenance technicians and serious DIY users who need a reliable fractional-size bit for everyday workshop tasks. The conventional 118-degree point angle provides effective centring and chip evacuation across common materials.
Upgrade from worn or uncoated fractional bits
The TiN coating on this 37/64 inch bit reduces friction and heat buildup, extending cutting life compared to bright-finish high-speed steel equivalents. The jump is worth it when drilling harder steels or running higher volumes where frequent resharpening of uncoated bits slows productivity. It replaces dull or damaged jobber-length bits of the same fractional diameter without requiring a change in drill chuck capacity or drilling technique.
Fits standard 1/2 inch chucks
The 0.5781 inch decimal equivalent shank fits any drill press or hand drill with a 1/2 inch or larger chuck, needing no special adapters or coolant-through capability. The TiN surface treatment frees up operator time by delaying the dulling that forces bit changes or bench grinding. It is not for buyers who need coolant-fed drilling, metric diameters, or split-point geometry for precision starting on hardened alloys.

Questions about this item
What shank diameter does the 37/64" jobber drill bit need in a chuck?
The bit has a 37/64 inch shank, so it requires a chuck that opens to at least 0.5781 inch.
How do I install the 118° conventional point bit without it walking on hard steel?
Centre-punch the workpiece, start drilling at low RPM with steady pressure, and let the 118° point self-centre before increasing speed.
When should I replace the high-speed steel TiN bit?
Replace it when the cutting lips show visible rounding, the tip discolours from overheating, or holes become oversized and rough.
