Chicago-Latrobe 44237 37/64" HSS TiN 118° Jobber Drill Bit

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.
